## Remarks
 The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified>.

 For applications in which portability of date and time data or a limited degree of time zone awareness is important, you can use the corresponding <xref:System.DateTimeOffset> constructor.



## Examples
 The following example demonstrates one of the <xref:System.DateTime> constructors.

## Remarks
 This constructor interprets `year`, `month`, and `day` as a year, month, and day in the Gregorian calendar. To instantiate a <xref:System.DateTime> value by using the year, month, and day in another calendar, call the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%29> constructor.

 The time of day for the resulting <xref:System.DateTime> is midnight (00:00:00). The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>.



## Examples
 The following example uses the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%29> constructor to instantiate a <xref:System.DateTime> value. The example also illustrates that this overload creates a <xref:System.DateTime> value whose time component equals midnight (or 0:00).

## Remarks
 The time of day for the resulting <xref:System.DateTime> is midnight (00:00:00). The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified>.

 The allowable values for `year`, `month`, and `day` depend on `calendar`. An exception is thrown if the specified date and time cannot be expressed using `calendar`.

 The <xref:System.Globalization> namespace provides several calendars including <xref:System.Globalization.GregorianCalendar> and <xref:System.Globalization.JulianCalendar>.



## Examples
 The following example calls the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%29> constructor twice to instantiate two <xref:System.DateTime> values. The first call instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.PersianCalendar> object. Because the Persian calendar cannot be designated as the default calendar for a culture, displaying a date in the Persian calendar requires individual calls to its <xref:System.Globalization.PersianCalendar.GetMonth%2A?displayProperty=nameWithType>, <xref:System.Globalization.PersianCalendar.GetDayOfMonth%2A?displayProperty=nameWithType>, and <xref:System.Globalization.PersianCalendar.GetYear%2A?displayProperty=nameWithType> methods. The second call to the constructor instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.HijriCalendar> object. The example changes the current culture to Arabic (Syria) and changes the current culture's default calendar to the Hijri calendar. Because Hijri is the current culture's default calendar, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses it to format the date. When the previous current culture (which is English (United States) in this case) is restored, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses the current culture's default Gregorian calendar to format the date.

## Remarks
 The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified>.

 This constructor interprets`year`, `month`, and `day` as a year, month, and day in the Gregorian calendar. To instantiate a <xref:System.DateTime> value by using the year, month, and day in another calendar, call the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%29> constructor.

 For applications in which portability of date and time data or a limited degree of time zone awareness is important, you can use the corresponding <xref:System.DateTimeOffset> constructor.



## Examples
 The following example uses the <xref:System.DateTime.%23ctor%2A> constructor to instantiate a <xref:System.DateTime> value.

## Remarks
 The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified>.

 The allowable values for `year`, `month`, and `day` depend on `calendar`. An exception is thrown if the specified date and time cannot be expressed using `calendar`.

[!INCLUDE[japanese-era-note](~/includes/calendar-era.md)]

 The <xref:System.Globalization> namespace provides several calendars including <xref:System.Globalization.GregorianCalendar> and <xref:System.Globalization.JulianCalendar>.



## Examples
 The following example calls the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%29> constructor twice to instantiate two <xref:System.DateTime> values. The first call instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.PersianCalendar> object. Because the Persian calendar cannot be designated as the default calendar for a culture, displaying a date in the Persian calendar requires individual calls to its <xref:System.Globalization.PersianCalendar.GetMonth%2A?displayProperty=nameWithType>, <xref:System.Globalization.PersianCalendar.GetDayOfMonth%2A?displayProperty=nameWithType>, and <xref:System.Globalization.PersianCalendar.GetYear%2A?displayProperty=nameWithType> methods. The second call to the constructor instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.HijriCalendar> object. The example changes the current culture to Arabic (Syria) and changes the current culture's default calendar to the Hijri calendar. Because Hijri is the current culture's default calendar, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses it to format the date. When the previous current culture (which is English (United States) in this case) is restored, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses the current culture's default Gregorian calendar to format the date.

## Remarks
 This constructor interprets`year`, `month`, and `day` as a year, month, and day in the Gregorian calendar. To instantiate a <xref:System.DateTime> value by using the year, month, and day in another calendar, call the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%29> constructor.

 The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified>.

 For applications in which portability of date and time data or a limited degree of time zone awareness is important, you can use the corresponding <xref:System.DateTimeOffset> constructor.



## Examples
 The following example uses the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%29> constructor to instantiate a <xref:System.DateTime> value.

## Remarks
 This constructor interprets`year`, `month`, and `day` as a year, month, and day in the Gregorian calendar. To instantiate a <xref:System.DateTime> value by using the year, month, and day in another calendar, call the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%2CSystem.DateTimeKind%29> constructor.

 For applications in which portability of date and time data or a limited degree of time zone awareness is important, you can use the corresponding <xref:System.DateTimeOffset> constructor.



## Examples
 The following example uses the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.DateTimeKind%29> constructor to instantiate a <xref:System.DateTime> value.

## Remarks
 The <xref:System.DateTime.Kind%2A> property is initialized to <xref:System.DateTimeKind.Unspecified>.

 The allowable values for `year`, `month`, and `day` depend on `calendar`. An exception is thrown if the specified date and time cannot be expressed using `calendar`.

 For applications in which portability of date and time data or a limited degree of time zone awareness is important, you can use the corresponding <xref:System.DateTimeOffset> constructor.

[!INCLUDE[japanese-era-note](~/includes/calendar-era.md)]

 The <xref:System.Globalization> namespace provides several calendars including <xref:System.Globalization.GregorianCalendar> and <xref:System.Globalization.JulianCalendar>.



## Examples
 The following example calls the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%29> constructor twice to instantiate two <xref:System.DateTime> values. The first call instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.PersianCalendar> object. Because the Persian calendar cannot be designated as the default calendar for a culture, displaying a date in the Persian calendar requires individual calls to its <xref:System.Globalization.PersianCalendar.GetMonth%2A?displayProperty=nameWithType>, <xref:System.Globalization.PersianCalendar.GetDayOfMonth%2A?displayProperty=nameWithType>, and <xref:System.Globalization.PersianCalendar.GetYear%2A?displayProperty=nameWithType> methods. The second call to the constructor instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.HijriCalendar> object. The example changes the current culture to Arabic (Syria) and changes the current culture's default calendar to the Hijri calendar. Because Hijri is the current culture's default calendar, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses it to format the date. When the previous current culture (which is English (United States) in this case) is restored, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses the current culture's default Gregorian calendar to format the date.

## Remarks
 The allowable values for `year`, `month`, and `day` parameters depend on the `calendar` parameter. An exception is thrown if the specified date and time cannot be expressed using `calendar`.

 For applications in which portability of date and time data or a limited degree of time zone awareness is important, you can use the corresponding <xref:System.DateTimeOffset> constructor.

[!INCLUDE[japanese-era-note](~/includes/calendar-era.md)]

 The <xref:System.Globalization> namespace provides several calendars including <xref:System.Globalization.GregorianCalendar> and <xref:System.Globalization.JulianCalendar>.



## Examples
 The following example calls the <xref:System.DateTime.%23ctor%28System.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Int32%2CSystem.Globalization.Calendar%2CSystem.DateTimeKind%29> constructor twice to instantiate two <xref:System.DateTime> values. The first call instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.PersianCalendar> object. Because the Persian calendar cannot be designated as the default calendar for a culture, displaying a date in the Persian calendar requires individual calls to its <xref:System.Globalization.PersianCalendar.GetMonth%2A?displayProperty=nameWithType>, <xref:System.Globalization.PersianCalendar.GetDayOfMonth%2A?displayProperty=nameWithType>, and <xref:System.Globalization.PersianCalendar.GetYear%2A?displayProperty=nameWithType> methods. The second call to the constructor instantiates a <xref:System.DateTime> value by using a <xref:System.Globalization.HijriCalendar> object. The example changes the current culture to Arabic (Syria) and changes the current culture's default calendar to the Hijri calendar. Because Hijri is the current culture's default calendar, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses it to format the date. When the previous current culture (which is English (United States) in this case) is restored, the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method uses the current culture's default Gregorian calendar to format the date.

## Remarks

The allowable values for `year`, `month`, and `day` parameters
             depend on the `calendar` parameter. An exception is thrown if the specified date and time cannot
             be expressed using `calendar`.

For applications in which portability of date and time data or a limited degree of time zone awareness is important,
             you can use the corresponding <xref:System.DateTimeOffset> constructor.

## Remarks
 You can use the <xref:System.DateTime.Add%2A> method to add more than one kind of time interval (days, hours, minutes, seconds, or milliseconds) in a single operation. This method's behavior is identical to that of the addition operator. The <xref:System.DateTime> structure also supports specialized addition methods (such as <xref:System.DateTime.AddDays%2A>, <xref:System.DateTime.AddHours%2A>, and <xref:System.DateTime.AddMinutes%2A>) for each time interval.

 The <xref:System.DateTime.Add%2A> method takes into account leap years and the number of days in a month when performing date arithmetic.

 This method does not change the value of this <xref:System.DateTime>. Instead, it returns a new <xref:System.DateTime> whose value is the result of this operation. The <xref:System.DateTime.Kind%2A> property of the new <xref:System.DateTime> instance is the same as that of the current instance.



## Examples
 The following example demonstrates the <xref:System.DateTime.Add%2A> method. It calculates the day of the week that is 36 days (864 hours) from this moment.

## Remarks
 This method does not change the value of this <xref:System.DateTime>. Instead, it returns a new <xref:System.DateTime> whose value is the result of this operation.

 The fractional part of `value` is the fractional part of a day. For example, 4.5 is equivalent to 4 days, 12 hours, 0 minutes, 0 seconds, 0 milliseconds, and 0 ticks.

 In .NET 6 and earlier versions, the `value` parameter is rounded to the nearest millisecond. In .NET 7 and later versions, the full <xref:System.Double> precision of the `value` parameter is used. However, due to the inherent imprecision of floating point math, the resulting precision will vary.

 The <xref:System.DateTime.AddDays%2A> method takes into account leap years and the number of days in a month when performing date arithmetic.

## Examples
 The following example uses the <xref:System.DateTime.AddDays%2A> method to determine the day of the week 36 days after the current date.

## Remarks
 This method does not change the value of this <xref:System.DateTime>. Instead, it returns a new <xref:System.DateTime> whose value is the result of this operation. The <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is the same as that of `value`.

 The fractional part of `value` is the fractional part of an hour. For example, 4.5 is equivalent to 4 hours, 30 minutes, 0 seconds, 0 milliseconds, and 0 ticks.

 In .NET 6 and earlier versions, the `value` parameter is rounded to the nearest millisecond. In .NET 7 and later versions, the full <xref:System.Double> precision of the `value` parameter is used. However, due to the inherent imprecision of floating point math, the resulting precision will vary.

 Converting time intervals of less than an hour to a fraction can involve a loss of precision if the result is a non-terminating repeating decimal. (For example, one minute is 0.016667 of an hour.) If this is problematic, you can use the <xref:System.DateTime.Add%2A> method, which enables you to specify more than one kind of time interval in a single method call and eliminates the need to convert time intervals to fractional parts of an hour.

## Examples
 The following example uses the <xref:System.DateTime.AddHours%2A> method to add a number of whole and fractional values to a date and time. It also illustrates the loss of precision caused by passing the method a value that includes a fractional component.

## Remarks
 This method does not change the value of this <xref:System.DateTime>. Instead, it returns a new <xref:System.DateTime> whose value is the result of this operation.

 The fractional part of `value` is the fractional part of a millisecond. For example, 4.5 is equivalent to 4 milliseconds and 5000 ticks, where one millisecond = 10000 ticks.

 In .NET 6 and earlier versions, the `value` parameter is rounded to the nearest millisecond. In .NET 7 and later versions, the full <xref:System.Double> precision of the `value` parameter is used. However, due to the inherent imprecision of floating point math, the resulting precision will vary.

## Examples
 The following example uses the <xref:System.DateTime.AddMilliseconds%2A> method to add one millisecond and 1.5 milliseconds to a <xref:System.DateTime> value. It then displays each new value and displays the difference between it and the original value. The difference is displayed both as a time span and as a number of ticks. The example makes it clear that one millisecond equals 10,000 ticks. It also shows that fractional milliseconds are rounded before performing the addition; the <xref:System.DateTime> value that results from adding 1.5 milliseconds to the original date is 2 milliseconds greater than the original date.

## Remarks
 This method does not change the value of this <xref:System.DateTime>. Instead, it returns a new <xref:System.DateTime> whose value is the result of this operation.

 The fractional part of `value` is the fractional part of a minute. For example, 4.5 is equivalent to 4 minutes, 30 seconds, 0 milliseconds, and 0 ticks.

## Remarks
 This method does not change the value of this <xref:System.DateTime> object. Instead, it returns a new <xref:System.DateTime> object whose value is the result of this operation.

 The <xref:System.DateTime.AddMonths%2A> method calculates the resulting month and year, taking into account leap years and the number of days in a month, then adjusts the day part of the resulting <xref:System.DateTime> object. If the resulting day is not a valid day in the resulting month, the last valid day of the resulting month is used. For example, March 31st + 1 month = April 30th, and March 31st - 1 month = February 28 for a non-leap year and February 29 for a leap year.

 The time-of-day part of the resulting <xref:System.DateTime> object remains the same as this instance.



## Examples
 The following example adds between zero and fifteen months to the last day of December, 2015. In this case, the AddMonths method returns the date of the last day of each month, and successfully handles leap years.

## Remarks
 This method does not change the value of this <xref:System.DateTime> object. Instead, it returns a new <xref:System.DateTime> object whose value is the result of this operation.

 The <xref:System.DateTime.AddYears%2A> method calculates the resulting year taking into account leap years. The month and time-of-day part of the resulting <xref:System.DateTime> object remains the same as this instance.

 If the current instance represents the leap day in a leap year, the return value depends on the target date:

-   If `value` + <xref:System.DateTime.Year%2A?displayProperty=nameWithType> is also a leap year, the return value represents the leap day in that year. For example, if four years is added to February 29, 2012, the date returned is February 29, 2016.

-   If `value` + <xref:System.DateTime.Year%2A?displayProperty=nameWithType> is not a leap year, the return value represents the day before the leap day in that year. For example, if one year is added to February 29, 2012, the date returned is February 28, 2013.

 The following example illustrates using the <xref:System.DateTime.AddYears%2A> method with a <xref:System.DateTime> value that represents a leap year day. It displays the date for the fifteen years prior to and the fifteen years that follow February 29, 2000.

## Remarks
 To determine the relationship of `t1` to `t2`, the <xref:System.DateTime.Compare%2A> method compares the <xref:System.DateTime.Ticks%2A> property of `t1` and `t2` but ignores their <xref:System.DateTime.Kind%2A> property. Before comparing <xref:System.DateTime> objects, ensure that the objects represent times in the same time zone.



## Examples

 The following example demonstrates the <xref:System.DateTime.Compare%2A> method.

## Remarks
 To determine the relationship of the current instance to `value`, the <xref:System.DateTime.CompareTo%2A> method compares the <xref:System.DateTime.Ticks%2A> property of the current instance and `value` but ignores their <xref:System.DateTime.Kind%2A> property.  Before comparing <xref:System.DateTime> objects, make sure that the objects represent times in the same time zone. You can do this by comparing the values of their <xref:System.DateTime.Kind%2A> properties.

 This method implements the <xref:System.IComparable%601?displayProperty=nameWithType> interface and performs slightly better than the <xref:System.DateTime.CompareTo%28System.Object%29?displayProperty=nameWithType> method overload because it does not have to convert the `value` parameter to an object.

## Examples
 The following example instantiates three <xref:System.DateTime> objects, one that represents today's date, another that represents the date one year previously, and a third that represents the date one year in the future. It then calls the <xref:System.DateTime.CompareTo%28System.DateTime%29> method and displays the result of the comparison.

## Remarks
 To determine the relationship of the current instance to `value`, the <xref:System.DateTime.CompareTo%2A> method compares the <xref:System.DateTime.Ticks%2A> property of the current instance and `value` but ignores their <xref:System.DateTime.Kind%2A> property. Before comparing <xref:System.DateTime> objects, make sure that the objects represent times in the same time zone. You can do this by comparing the values of their <xref:System.DateTime.Kind%2A> properties.

 Any instance of <xref:System.DateTime>, regardless of its value, is considered greater than `null`.



## Examples
 The following example demonstrates the <xref:System.DateTime.CompareTo%2A> method.

## Remarks
 The value of the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is the same as that of the current instance.

 Because the <xref:System.DateTime> type represents both dates and times in a single type, it is important to avoid misinterpreting a date returned by the <xref:System.DateTime.Date%2A> property as a date and time.



## Examples
 The following example uses the <xref:System.DateTime.Date%2A> property to extract the date component of a <xref:System.DateTime> value with its time component set to zero (or 0:00:00, or midnight). It also illustrates that, depending on the format string used when displaying the <xref:System.DateTime> value, the time component can continue to appear in formatted output.

## Remarks
 The <xref:System.DateTime.Day%2A> property always returns the day of the month in the Gregorian calendar, even if the current <xref:System.DateTime> value was instantiated using some other calendar or if the current culture's default calendar is not the Gregorian calendar. To retrieve the day of the month of a particular date using some other calendar, call that calendar's <xref:System.Globalization.Calendar.GetDayOfMonth%2A?displayProperty=nameWithType> method. The following example uses both the <xref:System.DateTime.Day%2A> property and the <xref:System.Globalization.HijriCalendar.GetDayOfMonth%2A?displayProperty=nameWithType> method to retrieve the day of the month for a <xref:System.DateTime> value that is instantiated using the Hijri calendar.

 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.DateTime.Day/vb/Day1.vb" id="Snippet1":::

 Similarly, the following example uses both the <xref:System.DateTime.Day%2A> property and the <xref:System.Globalization.HijriCalendar.GetDayOfMonth%2A?displayProperty=nameWithType> method to retrieve the day of the month when the current culture is ar-SA, which uses Hijri as its default calendar.

## Remarks
 The value of the constants in the <xref:System.DayOfWeek> enumeration ranges from <xref:System.DayOfWeek.Sunday?displayProperty=nameWithType> to <xref:System.DayOfWeek.Saturday?displayProperty=nameWithType>. If cast to an integer, its value ranges from zero (which indicates <xref:System.DayOfWeek.Sunday?displayProperty=nameWithType>) to six (which indicates <xref:System.DayOfWeek.Saturday?displayProperty=nameWithType>).

 The <xref:System.DateTime.DayOfWeek%2A> property returns an enumerated constant; it does not reflect a system's regional and language settings. To retrieve a string representing a localized weekday name for a particular date, call one of the overloads of the <xref:System.DateTime.ToString%2A> method that includes a `format` parameter and pass it either the `ddd` or `dddd` custom format strings. For details, see [How to: Extract the Day of the Week from a Specific Date](/dotnet/standard/base-types/how-to-extract-the-day-of-the-week-from-a-specific-date).

## Remarks
 The <xref:System.DateTime.DayOfYear%2A> property takes leap years into account when it calculates the day of the year. The property value always reflects the day of the year in the Gregorian calendar, regardless of the current culture's current calendar. To retrieve the day of the year in a different calendar, call the <xref:System.Globalization.Calendar.GetDayOfYear%2A?displayProperty=nameWithType> method of that calendar.

## Examples
 The following example displays the day of the year of December 31 for the years 2010-2020 in the Gregorian calendar. Note that the example shows that December 31 is the 366th day of the year in leap years.

## Remarks
 The <xref:System.DateTime.DaysInMonth%2A> method always interprets `month` and `year` as the month and year of the Gregorian calendar even if the Gregorian calendar is not the current culture's current calendar. To get the number of days in a specified month of a particular calendar, call that calendar's <xref:System.Globalization.Calendar.GetDaysInMonth%2A> method.



## Examples
 The following example demonstrates how to use the <xref:System.DateTime.DaysInMonth%2A> method to determine the number of days in July 2001, February 1998 (a non-leap year), and February 1996 (a leap year).

## Remarks
 The current instance and `value` are equal if their <xref:System.DateTime.Ticks%2A> property values are equal. Their <xref:System.DateTime.Kind%2A> property values are not considered in the test for equality.

 This method implements the <xref:System.IEquatable%601?displayProperty=nameWithType> interface, and performs slightly better than the <xref:System.DateTime.Equals%2A> method because the `value` parameter does not have to be converted to an object.

## Examples
 The following example demonstrates the <xref:System.DateTime.Equals%2A> method.

## Remarks
 A Windows file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC). Windows uses a file time to record when an application creates, accesses, or writes to a file.

 The `fileTime` parameter specifies a file time expressed in 100-nanosecond ticks.

 Starting with the .NET Framework version 2.0, the return value is a <xref:System.DateTime> whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.



## Examples
 The following example demonstrates the <xref:System.DateTime.FromFileTime%2A> method.

          <para>Ordinarily, the <see cref="M:System.DateTime.FromFileTime(System.Int64)" /> method restores a <see cref="T:System.DateTime" /> value that was saved by the <see cref="M:System.DateTime.ToFileTime" /> method. However, the two values may differ under the following conditions:

-   If the serialization and deserialization of the <see cref="T:System.DateTime" /> value occur in different time zones. For example, if a <see cref="T:System.DateTime" /> value with a time of 12:30 P.M. in the U.S. Eastern Time zone is serialized, and then deserialized in the U.S. Pacific Time zone, the original value of 12:30 P.M. is adjusted to 9:30 A.M. to reflect the difference between the two time zones.

-   If the <see cref="T:System.DateTime" /> value that is serialized represents an invalid time in the local time zone. In this case, the <see cref="M:System.DateTime.ToFileTime" /> method adjusts the restored <see cref="T:System.DateTime" /> value so that it represents a valid time in the local time zone.

     For example, the transition from standard time to daylight saving time occurs in the U.S. Pacific Time zone on March 14, 2010, at 2:00 A.M., when the time advances by one hour, to 3:00 A.M. This hour interval is an invalid time, that is, a time interval that does not exist in this time zone. The following example shows that when a time that falls within this range is converted to a long integer value by the <see cref="M:System.DateTime.ToFileTime" /> method and is then restored by the <see cref="M:System.DateTime.FromFileTime(System.Int64)" /> method, the original value is adjusted to become a valid time. You can determine whether a particular date and time value may be subject to modification by passing it to the <see cref="M:System.TimeZoneInfo.IsInvalidTime(System.DateTime)" /> method, as the example illustrates.

## Remarks
 The `d` parameter is a double-precision floating-point number that represents a date as the number of days before or after the base date, midnight, 30 December 1899. The sign and integral part of `d` encode the date as a positive or negative day displacement from 30 December 1899, and the absolute value of the fractional part of `d` encodes the time of day as a fraction of a day displacement from midnight. `d` must be a value between negative 657435.0 through positive 2958465.99999999.

 Note that because of the way dates are encoded, there are two ways of representing any time of day on 30 December 1899. For example, -0.5 and 0.5 both mean noon on 30 December 1899 because a day displacement of plus or minus zero days from the base date is still the base date, and a half day displacement from midnight is noon.

 The string array returned by the <xref:System.DateTime.GetDateTimeFormats?displayProperty=nameWithType> method is equivalent to combining the string arrays returned by separate calls to the <xref:System.DateTime.GetDateTimeFormats%28System.Char%29?displayProperty=nameWithType> method with the "d", "D", "f", "F", "g", "G", "m", "o", "r", "s", "t", "T", "u", "U", and "y" standard format strings. For more information about standard format specifiers, see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings).

 Each element of the return value is formatted using information from the current culture. For more information about culture-specific formatting information for the current culture, see <xref:System.Globalization.CultureInfo.CurrentCulture%2A?displayProperty=nameWithType>.

> [!IMPORTANT]
>  Because this method uses culture-sensitive data, you should not assume that multiple calls to the method will return identical data.

## Remarks
 The `format` parameter can be any of the standard date and time format specifiers. These include d, D, f, F, g, G, M (or m), O (or o), R (or r), s, t, T, u, U, and Y (or y). For more information, see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings).

 Each element of the return value is formatted using information from the current culture. For more information about culture-specific formatting information for the current culture, see <xref:System.Globalization.CultureInfo.CurrentCulture%2A?displayProperty=nameWithType>.

> [!IMPORTANT]
>  Because this method uses culture-sensitive data, you should not assume that multiple calls to the method will return identical data.

## Examples
 The following example demonstrates the <xref:System.DateTime.GetDateTimeFormats%28System.Char%29> method. It displays the string representation of a date using the long date format specifier ("D") for the current culture.

## Remarks
 The string array returned by the <xref:System.DateTime.GetDateTimeFormats%28System.IFormatProvider%29?displayProperty=nameWithType> method is equivalent to combining the string arrays returned by separate calls to the <xref:System.DateTime.GetDateTimeFormats%28System.Char%2CSystem.IFormatProvider%29?displayProperty=nameWithType> method with the "d", "D", "f", "F", "g", "G", "m", "o", "r", "s", "t", "T", "u", "U", and "y" standard format strings. For more information about standard format specifiers, see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings).

 Each element of the return value is formatted using culture-specific information supplied by `provider`.

> [!IMPORTANT]
>  Because this method uses culture-sensitive data, you should not assume that multiple calls to the method will return identical data unless `provider` is a <xref:System.Globalization.CultureInfo> object that represents the invariant culture. The data returned by this method can change if the user overrides the individual cultural settings of `provider` or if an update occurs to the system's cultural data for `provider`.



## Examples
 The following example demonstrates the <xref:System.DateTime.GetDateTimeFormats%28System.IFormatProvider%29?displayProperty=nameWithType> method. It displays the string representation of a date using all possible standard date and time formats for the fr-FR culture.

## Remarks
 The format parameter can be any of the standard date and time format specifiers. These include d, D, f, F, g, G, M (or m), O (or o), R (or r), s, t, T, u, U, and Y (or y). For more information, see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings).

 Each element of the return value is formatted using culture-specific information supplied by `provider`.

> [!IMPORTANT]
>  Because this method uses culture-sensitive data, you should not assume that multiple calls to the method will return identical data unless `provider` is a <xref:System.Globalization.CultureInfo> object that represents the invariant culture. The data returned by this method can change if the user overrides the individual cultural settings of `provider` or if an update occurs to the system's cultural data for `provider`.



## Examples
 The following example demonstrates the <xref:System.DateTime.GetDateTimeFormats%28System.Char%2CSystem.IFormatProvider%29> method. It displays the string representations of a date using the short date format specifier ("d") for the fr-FR culture.

## Remarks
 The value of the <xref:System.DateTime.Hour%2A> property is always expressed using a 24-hour clock. To retrieve a string that represents the hour of a date and time using a 12-hour clock, call the <xref:System.DateTime.ToString%28System.String%29?displayProperty=nameWithType> or <xref:System.DateTime.ToString%28System.String%2CSystem.IFormatProvider%29?displayProperty=nameWithType> method with the "h" custom format specifier.

## Remarks
 This method determines whether the current <xref:System.DateTime> value falls within the daylight saving time range of the local time zone, which is returned by the <xref:System.TimeZoneInfo.Local%2A?displayProperty=nameWithType> property. You can determine whether a time zone supports daylight saving time by retrieving the value of its <xref:System.TimeZoneInfo.SupportsDaylightSavingTime%2A?displayProperty=nameWithType> property. For time zones that observe daylight saving time, you can determine when the transition to and from daylight saving time occurs by retrieving the <xref:System.TimeZoneInfo.AdjustmentRule?displayProperty=nameWithType> array returned by the time zone's <xref:System.TimeZoneInfo.GetAdjustmentRules%2A?displayProperty=nameWithType> property.

 If the current <xref:System.DateTime> value represents either an ambiguous or an invalid time in the local time zone, the method returns `false`.

 On Windows XP systems, the <xref:System.DateTime.IsDaylightSavingTime%2A> method recognizes only the current adjustment rule when determining whether the current instance is a daylight saving time. As a result, the method may not accurately report whether the current instance is a daylight saving time for periods before the current adjustment rule came into effect.

## Remarks
 `year` is specified as a 4-digit base 10 number; for example, 1996.

 `year` is always interpreted as a year in the Gregorian calendar. To determine whether a particular year was a leap year in some other calendar, call that calendar object's `IsLeapYear` method.



## Examples
 The following example uses the <xref:System.DateTime.IsLeapYear%2A> method to determine which years between 1994 and 2014 are leap years. The example also illustrates the result when the <xref:System.DateTime.AddYears%2A> method is used to add a year to a leap day.

## Remarks
 You can explicitly set the <xref:System.DateTime.Kind%2A> property of a new <xref:System.DateTime> value to a particular <xref:System.DateTimeKind> value by calling the <xref:System.DateTime.SpecifyKind%2A> method.

 The <xref:System.DateTime.Kind%2A> property allows a <xref:System.DateTime> value to clearly reflect either Coordinated Universal Time (UTC) or the local time. In contrast, the <xref:System.DateTimeOffset> structure can unambiguously reflect any time in any time zone as a single point in time.



## Examples
 The following example uses the <xref:System.DateTime.SpecifyKind%2A> method to demonstrate how the <xref:System.DateTime.Kind%2A> property influences the <xref:System.DateTime.ToLocalTime%2A> and <xref:System.DateTime.ToUniversalTime%2A> conversion methods.

## Remarks
 The value of this constant is equivalent to 23:59:59.9999999 UTC, December 31, 9999 in the Gregorian calendar, exactly one 100-nanosecond tick before 00:00:00 UTC, January 1, 10000.

 Some calendars, such as the <xref:System.Globalization.ThaiBuddhistCalendar>, support an upper date range that is earlier than <xref:System.DateTime.MaxValue>. In these cases, trying to access <xref:System.DateTime.MaxValue> in variable assignments or formatting and parsing operations can throw an <xref:System.ArgumentOutOfRangeException>. Rather than retrieving the value of <xref:System.DateTime.MaxValue?displayProperty=nameWithType>, you can retrieve the value of the specified culture's latest valid date value from the <xref:System.Globalization.Calendar.MaxSupportedDateTime?displayProperty=nameWithType> property.



## Examples
 The following example instantiates a <xref:System.DateTime> object by passing its constructor an <xref:System.Int64> value that represents a number of ticks. Before invoking the constructor, the example ensures that this value is greater than or equal to `DateTime.MinValue.Ticks` and less than or equal to `DateTime.MaxValue.Ticks`. If not, it throws an <xref:System.ArgumentOutOfRangeException>.

## Remarks
 You can display the string representation of the <xref:System.DateTime.Millisecond%2A> property by using the "fff" format specifier. For example, the following code displays a string that contains the number of milliseconds in a date and time to the console.

 :::code language="csharp" source="~/snippets/csharp/System/DateTime/Millisecond/Millisecond.cs" interactive="try-dotnet-method" id="Snippet1":::
 :::code language="fsharp" source="~/snippets/fsharp/VS_Snippets_CLR_System/system.DateTime.Millisecond/fs/Millisecond.fs" id="Snippet1":::
 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.DateTime.Millisecond/vb/Millisecond.vb" id="Snippet1":::

 You can also display the millisecond component together with the other components of a date and time value by using the "o" standard format specifier. For example:

 :::code language="csharp" source="~/snippets/csharp/System/DateTime/Millisecond/Millisecond.cs" interactive="try-dotnet-method" id="Snippet2":::
 :::code language="fsharp" source="~/snippets/fsharp/VS_Snippets_CLR_System/system.DateTime.Millisecond/fs/Millisecond.fs" id="Snippet2":::
 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.DateTime.Millisecond/vb/Millisecond.vb" id="Snippet2":::

 However, the "o" format specifier is intended less for displaying than for round-tripping or storing a <xref:System.DateTime> value. You can also display milliseconds together with other date and time components by using a custom format string, as the following example shows.

 :::code language="csharp" source="~/snippets/csharp/System/DateTime/Millisecond/Millisecond.cs" interactive="try-dotnet-method" id="Snippet3":::
 :::code language="fsharp" source="~/snippets/fsharp/VS_Snippets_CLR_System/system.DateTime.Millisecond/fs/Millisecond.fs" id="Snippet3":::
 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.DateTime.Millisecond/vb/Millisecond.vb" id="Snippet3":::

## Remarks
 The value of this constant is equivalent to 00:00:00.0000000 UTC, January 1, 0001, in the Gregorian calendar.

 <xref:System.DateTime.MinValue> defines the date and time that is assigned to an uninitialized <xref:System.DateTime> variable. The following example illustrates this.

 :::code language="csharp" source="~/snippets/csharp/System/DateTime/MaxValue/MinValue.cs" id="Snippet1":::
 :::code language="fsharp" source="~/snippets/fsharp/VS_Snippets_CLR_System/system.DateTime.MinValue/fs/MinValue.fs" id="Snippet1":::
 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.DateTime.MinValue/vb/MinValue.vb" id="Snippet1":::

 The <xref:System.DateTime.MinValue> and <xref:System.DateTime.MaxValue> properties can be used to ensure that a value lies within the supported range before passing it to a <xref:System.DateTime> constructor. The code in the Example section illustrates this usage.



## Examples
 The following example instantiates a <xref:System.DateTime> object by passing its constructor an <xref:System.Int64> value that represents a number of ticks. Before invoking the constructor, the example ensures that this value is greater than or equal to `DateTime.MinValue.Ticks` and less than or equal to `DateTime.MaxValue.Ticks`. If not, it throws an <xref:System.ArgumentOutOfRangeException>.

## Remarks
 The <xref:System.DateTime.Now%2A> property returns a <xref:System.DateTime> value that represents the current date and time on the local computer. Note that there is a difference between a <xref:System.DateTime> value, which represents the number of ticks that have elapsed since midnight of January 1, 0001, and the string representation of that <xref:System.DateTime> value, which expresses a date and time value in a culture-specific-specific format. For information on formatting date and time values, see the <xref:System.DateTime.ToString%2A> method. The following example displays the short date and time string in a number of culture-specific formats.

 :::code language="cpp" source="~/snippets/cpp/VS_Snippets_CLR_System/system.datetime.now/cpp/now1.cpp" id="Snippet2":::
 :::code language="csharp" source="~/snippets/csharp/System/DateTime/Now/now1.cs" id="Snippet2":::
 :::code language="fsharp" source="~/snippets/fsharp/VS_Snippets_CLR_System/system.datetime.now/fs/now1.fs" id="Snippet2":::
 :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.datetime.now/vb/now1.vb" id="Snippet2":::

 The resolution of this property depends on the system timer, which depends on the underlying operating system. It tends to be between 0.5 and 15 milliseconds. As a result, repeated calls to the <xref:System.DateTime.Now%2A> property in a short time interval, such as in a loop, may return the same value.

 The <xref:System.DateTime.Now%2A> property is frequently used to measure performance. However, because of its low resolution, it is not suitable for use as a benchmarking tool. A better alternative is to use the <xref:System.Diagnostics.Stopwatch> class.

 Starting with the .NET Framework version 2.0, the return value is a <xref:System.DateTime> whose <xref:System.DateTime.Kind%2A> property returns <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.

> [!NOTE]
>  You can also use the <xref:System.DateTimeOffset.Now%2A?displayProperty=nameWithType> property to retrieve the current local date and time. It allows a local time to be expressed unambiguously as a single point in time, which in turn makes that time value portable across computers.



## Examples
 The following example uses the <xref:System.DateTime.Now%2A> and <xref:System.DateTime.UtcNow%2A> properties to retrieve the current local date and time and the current universal coordinated (UTC) date and time. It then uses the formatting conventions of a number of cultures to display the strings, along with the values of their <xref:System.DateTime.Kind%2A> properties.

## Remarks
 The <xref:System.DateTime.op_Equality%2A> operator determines whether two <xref:System.DateTime> values are equal by comparing their number of ticks. Before comparing <xref:System.DateTime> objects, make sure that the objects represent times in the same time zone. You can do this by comparing the values of their <xref:System.DateTime.Kind%2A> property.

 The equivalent method for this operator is <xref:System.DateTime.Equals%28System.Object%29?displayProperty=nameWithType>

## Examples
 The following example demonstrates the equality operator.

 The <xref:System.DateTime.op_GreaterThan%2A> operator determines the relationship between two <xref:System.DateTime> values by comparing their number of ticks. Before comparing <xref:System.DateTime> objects, make sure that the objects represent times in the same time zone. You can do this by comparing the values of their <xref:System.DateTime.Kind%2A> property.

 The equivalent method for this operator is <xref:System.DateTime.Compare%28System.DateTime%2CSystem.DateTime%29?displayProperty=nameWithType>]]></format>

## Remarks
 The <xref:System.DateTime.op_Subtraction%28System.DateTime%2CSystem.DateTime%29> method does not consider the value of the <xref:System.DateTime.Kind%2A> property of the two <xref:System.DateTime> values when performing the subtraction. Before subtracting <xref:System.DateTime> objects, ensure that the objects represent times in the same time zone. Otherwise, the result will include the difference between time zones.

> [!NOTE]
>  The <xref:System.DateTimeOffset.op_Subtraction%28System.DateTimeOffset%2CSystem.DateTimeOffset%29?displayProperty=nameWithType> method does consider the difference between time zones when performing the subtraction.

 The equivalent method for this operator is <xref:System.DateTime.Subtract%28System.DateTime%29?displayProperty=nameWithType>

## Examples
 The following example demonstrates the <xref:System.DateTime.Subtract%2A> method and the subtraction operator.

### Which method do I call?

|To|Call|
|--------|----------|
|Parse a date and time string by using the conventions of the current culture.|<xref:System.DateTime.Parse%28System.String%29> overload|
|Parse a date and time string by using the conventions of a specific culture.|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%29> overload (see [Parsing and Cultural Conventions](#Culture))|
|Parse a date and time string with special style elements (such as white space or no white space).|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> overload|
|Parse a date and time string that must be in a particular format.|<xref:System.DateTime.ParseExact%2A?displayProperty=nameWithType> or <xref:System.DateTime.TryParseExact%2A?displayProperty=nameWithType>|
|Parse a date and time string and perform a conversion to UTC or local time.|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> overload|
|Parse a date and time string without handling exceptions.|<xref:System.DateTime.TryParse%2A?displayProperty=nameWithType> method|
|Restore (round-trip) a date and time value created by a formatting operation.|Pass the "o" or "r" standard format string to the <xref:System.DateTime.ToString%28System.String%29> method, and call the <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> overload with <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType>|
|Parse a date and time string in a fixed format across machine (and possibly cultural) boundaries.|<xref:System.DateTime.ParseExact%2A?displayProperty=nameWithType> or <xref:System.DateTime.TryParseExact%2A?displayProperty=nameWithType> method|

<a name="StringToParse"></a>
### The string to parse
 The <xref:System.DateTime.Parse%2A> method tries to convert the string representation of a date and time value to its <xref:System.DateTime> equivalent. It tries to parse the input string completely without throwing a <xref:System.FormatException> exception.

> [!IMPORTANT]
>  If the parsing operation fails because of an unrecognized string format, the <xref:System.DateTime.Parse%2A> method throws a <xref:System.FormatException>, whereas the <xref:System.DateTime.TryParse%2A> method returns `false`. Because exception handling can be expensive, you should use <xref:System.DateTime.Parse%2A> when the parsing operation is expected to succeed because the input source is trusted. <xref:System.DateTime.TryParse%2A> is preferable when parsing failures are likely, particularly because an input source is not trusted, or you have reasonable default values to substitute for strings that do not parse successfully.

 The string to be parsed can take any of the following forms:

-   A string with a date and a time component.

-   A string with a date but no time component. If the time component is absent, the method assumes 12:00 midnight. If the date component has a two-digit year, it is converted to a year based on the <xref:System.Globalization.Calendar.TwoDigitYearMax%2A?displayProperty=nameWithType> of the current culture's current calendar or the specified culture's current calendar (if you use an overload with a non-null `provider` argument).

- A string with a date component that includes only the month and the year but no day component. The method assumes the first day of the month.

- A string with a date component that includes only the month and the day but no year component. The method assumes the current year.

-   A string with a time but no date component. The method assumes the current date unless you call the <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> overload and include <xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault?displayProperty=nameWithType> in the `styles` argument, in which case the method assumes a date of January 1, 0001.

- A string with a time component that includes only the hour and an AM/PM designator, with no date component. The method assumes the current date and a time with no minutes and no seconds. You can change this behavior by calling the <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> overload and include <xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault?displayProperty=nameWithType> in the `styles` argument, in which case the method assumes a date of January 1, 0001.

-   A string that includes time zone information and conforms to ISO 8601. In the following examples, the first string designates Coordinated Universal Time (UTC), and the second designates the time in a time zone that's seven hours earlier than UTC:

    "2008-11-01T19:35:00.0000000Z"
    "2008-11-01T19:35:00.0000000-07:00"

-   A string that includes the GMT designator and conforms to the RFC 1123 time format; for example:

     "Sat, 01 Nov 2008 19:35:00 GMT"

-   A string that includes the date and time along with time zone offset information; for example:

     "03/01/2009 05:42:00 -5:00"

The following example parses strings in each of these formats by using the formatting conventions of the current culture, which in this case is the en-US culture:

:::code language="csharp" source="~/snippets/csharp/System/DateTime/Parse/Parse6.cs":::
:::code language="fsharp" source="~/snippets/fsharp/VS_Snippets_CLR_System/system.DateTime.Parse/fs/Parse6.fs":::
:::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR_System/system.DateTime.Parse/vb/Parse6.vb":::

 If the input string represents a leap day in a leap year in the calendar used by the parsing method (see [Parsing and cultural conventions](#Culture)), the <xref:System.DateTime.Parse%2A> method parses the string successfully. If the input string represents a leap day in a non-leap year, the method throws a <xref:System.FormatException>.

 Because the <xref:System.DateTime.Parse%2A> method tries to parse the string representation of a date and time by using the formatting rules of the current or a specified culture, trying to parse a string across different cultures can fail. To parse a specific date and time format across different locales, use one of the overloads of the <xref:System.DateTime.ParseExact%2A?displayProperty=nameWithType> method and provide a format specifier.

<a name="Culture"></a>
### Parsing and cultural conventions
 All overloads of the <xref:System.DateTime.Parse%2A> method are culture-sensitive unless the string to be parsed (which is represented by `s` in the following table) conforms to the ISO 8601 pattern. The parsing operation uses the formatting information in a <xref:System.Globalization.DateTimeFormatInfo> object that is derived as follows:

[!INCLUDE[japanese-era-note](~/includes/calendar-era.md)]

|If you call|And `provider` is|Formatting information is derived from|
|-----------------|-----------------------|--------------------------------------------|
|<xref:System.DateTime.Parse%28System.String%29>|-|The current culture (<xref:System.Globalization.DateTimeFormatInfo.CurrentInfo%2A?displayProperty=nameWithType> property)|
|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%29> or <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29>|a <xref:System.Globalization.DateTimeFormatInfo> object|The specified <xref:System.Globalization.DateTimeFormatInfo> object|
|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%29> or <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29>|`null`|The current culture (<xref:System.Globalization.DateTimeFormatInfo.CurrentInfo%2A?displayProperty=nameWithType> property)|
|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%29> or <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29>|a <xref:System.Globalization.CultureInfo> object|The <xref:System.Globalization.CultureInfo.DateTimeFormat%2A?displayProperty=nameWithType> property|
|<xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%29> or <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29>|Custom <xref:System.IFormatProvider> implementation|The <xref:System.IFormatProvider.GetFormat%2A?displayProperty=nameWithType> method|

 When formatting information is derived from a <xref:System.Globalization.DateTimeFormatInfo> object, the <xref:System.Globalization.DateTimeFormatInfo.Calendar%2A?displayProperty=nameWithType> property defines the calendar used in the parsing operation.

 If you parse a date and time string by using a <xref:System.Globalization.DateTimeFormatInfo> object with customized settings that are different from those of a standard culture, use the <xref:System.DateTime.ParseExact%2A> method instead of the <xref:System.DateTime.Parse%2A> method to improve the chances for a successful conversion. A non-standard date and time string can be complicated and difficult to parse. The <xref:System.DateTime.Parse%2A> method tries to parse a string with several implicit parse patterns, all of which might fail. In contrast, the <xref:System.DateTime.ParseExact%2A> method requires you to explicitly designate one or more exact parse patterns that are likely to succeed. For more information, see the "DateTimeFormatInfo and Dynamic Data" section in the <xref:System.Globalization.DateTimeFormatInfo> topic.

> [!IMPORTANT]
>  Note that the formatting conventions for a particular culture are dynamic and can be subject to change. This means that parsing operations that depend on the formatting conventions of the default (current) culture or that specify an <xref:System.IFormatProvider> object that represents a culture other than the invariant culture can unexpectedly fail if any of the following occurs:
>
> -   The culture-specific data has changed between major or minor versions of the .NET Framework or as the result of an update to the existing version of the .NET Framework.
> -   The culture-specific data reflects user preferences, which can vary from machine to machine or session to session.
> -   The culture-specific data represents a replacement culture that overrides the settings of a standard culture or a custom culture.
>
>  To prevent the difficulties in parsing data and time strings that are associated with changes in cultural data, you can parse date and time strings by using the invariant culture, or you can call the <xref:System.DateTime.ParseExact%2A> or <xref:System.DateTime.TryParseExact%2A> method and specify the exact format of the string to be parsed. If you are serializing and deserializing date and time data, you can either use the formatting conventions of the invariant culture, or you can serialize and deserialize the <xref:System.DateTime> value in a binary format.
>
>  For more information see the "Dynamic culture data" section in the <xref:System.Globalization.CultureInfo> topic and the "Persisting DateTime values" section in the <xref:System.DateTime> topic.

<a name="Styles"></a>
### Parsing and style elements
 All <xref:System.DateTime.Parse%2A> overloads ignore leading, inner, or trailing white-space characters in the input string (which is represented by `s` in the following table). The date and time can be bracketed with a pair of leading and trailing NUMBER SIGN characters ("#", U+0023), and can be trailed with one or more NULL characters (U+0000).

 In addition, the <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> overload has a `styles` parameter that consists of one or more members of the <xref:System.Globalization.DateTimeStyles> enumeration. This parameter defines how `s` should be interpreted and how the parse operation should convert `s` to a date and time. The following table describes the effect of each <xref:System.Globalization.DateTimeStyles> member on the parse operation.

|DateTimeStyles member|Effect on conversion|
|---------------------------|--------------------------|
|<xref:System.Globalization.DateTimeStyles.AdjustToUniversal>|Parses `s` and, if necessary, converts it to UTC, as follows:<br /><br /> -   If `s` includes a time zone offset, or if `s` contains no time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeLocal> flag, the method parses the string, calls <xref:System.DateTime.ToUniversalTime%2A> to convert the returned <xref:System.DateTime> value to UTC, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.<br />-   If `s` indicates that it represents UTC, or if `s` does not contain time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeUniversal> flag, the method parses the string, performs no time zone conversion on the returned <xref:System.DateTime> value, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.<br />-   In all other cases, the flag has no effect.|
|<xref:System.Globalization.DateTimeStyles.AllowInnerWhite>|This value is ignored. Inner white space is always permitted in the date and time elements of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowLeadingWhite>|This value is ignored. Leading white space is always permitted in the date and time elements of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowTrailingWhite>|This value is ignored. Trailing white space is always permitted in the date and time elements of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces>|Specifies that `s` may contain leading, inner, and trailing white spaces. This is the default behavior. It cannot be overridden by supplying a more restrictive <xref:System.Globalization.DateTimeStyles> enumeration value such as <xref:System.Globalization.DateTimeStyles.None>.|
|<xref:System.Globalization.DateTimeStyles.AssumeLocal>|Specifies that if `s` lacks any time zone information, local time is assumed. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal> flag is present, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.AssumeUniversal>|Specifies that if `s` lacks any time zone information, UTC is assumed. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal> flag is present, the method converts the returned <xref:System.DateTime> value from UTC to local time and sets its <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.None>|Although valid, this value is ignored.|
|<xref:System.Globalization.DateTimeStyles.RoundtripKind>|For strings that contain time zone information, tries to prevent the conversion of a date and time string to a <xref:System.DateTime> value that represents a local time with its <xref:System.DateTime.Kind%2A> property set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. Typically, such a string is created by calling the <xref:System.DateTime.ToString%28System.String%29?displayProperty=nameWithType> method and by using the "o", "r", or "u" standard format specifier.|

<a name="kind"></a>
### The return value and DateTime.Kind

The `DateTime.Parse` overloads return a <xref:System.DateTime> value whose <xref:System.DateTime.Kind> property includes time zone information. It can indicate that the time is:

- Coordinated Universal Time (<xref:System.DateTimeKind.Utc?displayProperty=fullName>).
- The time in the local time zone (<xref:System.DateTimeKind.Local?displayProperty=fullName>).
- The time in an unknown time zone (<xref:System.DateTimeKind.Unspecified?displayProperty=fullName>).

 Generally, the <xref:System.DateTime.Parse%2A> method returns a <xref:System.DateTime> object whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. However, the <xref:System.DateTime.Parse%2A> method may also perform time zone conversion and set the value of the <xref:System.DateTime.Kind%2A> property differently, depending on the values of the `s` and `styles` parameters:

|If|Time zone conversion|Kind property|
|--------|--------------------------|-------------------|
|`s` contains time zone information.|The date and time is converted to the time in the local time zone.|<xref:System.DateTimeKind.Local?displayProperty=nameWithType>|
|`s` contains time zone information, and `styles` includes the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal> flag.|The date and time is converted to Coordinated Universal Time (UTC).|<xref:System.DateTimeKind.Utc?displayProperty=nameWithType>|
|`s` contains the Z or GMT time zone designator, and `styles` includes the <xref:System.Globalization.DateTimeStyles.RoundtripKind> flag.|The date and time are interpreted as UTC.|<xref:System.DateTimeKind.Utc?displayProperty=nameWithType>|

 The following example converts date strings that contain time zone information to the time in the local time zone:

  You can also preserve the value of a date and time's <xref:System.DateTime.Kind%2A> property during a formatting and parsing operation by using the <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType> flag. The following example illustrates how the <xref:System.Globalization.DateTimeStyles.RoundtripKind> flag affects the parsing operation on <xref:System.DateTime> values that are converted to strings by using the "o", "r", or "u" format specifier.

## Remarks

If `s` contains time zone information, this method returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType> and converts the date and time in `s` to local time. Otherwise, it performs no time zone conversion and returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>.

This overload attempts to parse `s` by using the formatting conventions of the current culture. The current culture is indicated by the <xref:System.Globalization.CultureInfo.CurrentCulture> property. To parse a string using the formatting conventions of a specific culture, call the <xref:System.DateTime.Parse(System.String,System.IFormatProvider)> or the <xref:System.DateTime.Parse(System.String,System.IFormatProvider,System.Globalization.DateTimeStyles)> overloads.

This overload attempts to parse `s` by using <xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces?displayProperty=nameWithType> style.

## Examples

The following example parses the string representation of several date and time values by:

- Using the default format provider, which provides the formatting conventions of the current culture of the computer used to produce the example output. The output from this example reflects the formatting conventions of the en-US culture.

- Using the default style value, which is <xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces?displayProperty=nameWIthType>.

It handles the <xref:System.FormatException> exception that is thrown when the method tries to parse the string representation of a date and time by using some other culture's formatting conventions. It also shows how to successfully parse a date and time value that does not use the formatting conventions of the current culture.

The following example parses an array of date strings by using the conventions of the en-US, fr-FR, and de-DE cultures. It demonstrates that the string representations of a single date can be interpreted differently across different cultures.

## Remarks

This method overload converts the date and time in `s` and sets the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value as follows:

| If | Time zone conversion | Kind property |
|----|----------------------|---------------|
| `s` contains no time zone information. | None. | <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType> |
| `s` contains time zone information. | To the time in the local time zone | <xref:System.DateTimeKind.Local?displayProperty=nameWithType> |
| `s` contains time zone information, and `styles` includes the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag. | To Coordinated Universal Time (UTC) | <xref:System.DateTimeKind.Utc?displayProperty=nameWithType> |
| `s` contains the Z or GMT time zone designator, and `styles` includes the <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType>. | None. | <xref:System.DateTimeKind.Utc?displayProperty=nameWithType> |

## Examples

The following example demonstrates the <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> method and displays the value of the <xref:System.DateTime.Kind%2A> property of the resulting <xref:System.DateTime> values.

## Remarks
 The <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%29?displayProperty=nameWithType> method parses the string representation of a date, which must be in the format defined by the `format` parameter. It also requires that the \<Date> and \<Time> elements of the string representation of a date and time appear in the order specified by `format`, and that `s` have no white space other than that permitted by `format`. If `format` defines a date with no time element and the parse operation succeeds, the resulting <xref:System.DateTime> value has a time of midnight (00:00:00). If `format` defines a time with no date element and the parse operation succeeds, the resulting <xref:System.DateTime> value has a date of `DateTime.Now.Date`.

 If `s` does not represent a time in a particular time zone and the parse operation succeeds, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. If `s` does represent the time in a particular time zone and `format` allows time zone information to be present (for example, if `format` is equal to the "o", "r", or "u" standard format specifiers, or if it contains the "z", "zz", or "zzz" custom format specifiers), the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.

 The `format` parameter is a string that contains either a single standard format specifier, or one or more custom format specifiers that define the required format of `s`. For details about valid formatting codes, see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings) or [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings).

> [!NOTE]
>  If `format` is a custom format pattern that does not include date or time separators (such as "yyyyMMddHHmm"), use the invariant culture for the `provider` parameter and the widest form of each custom format specifier. For example, if you want to specify hours in the format pattern, specify the wider form, "HH", instead of the narrower form, "H".

 The particular date and time symbols and strings (such as names of the days of the week in a particular language) used in `s` are defined by the `provider` parameter, as is the precise format of `s` if `format` is a standard format specifier string. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture used to interpret `s`. The <xref:System.Globalization.DateTimeFormatInfo> object returned by its <xref:System.Globalization.CultureInfo.DateTimeFormat%2A> property defines the symbols and formatting in `s`.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom <xref:System.IFormatProvider> implementation whose <xref:System.IFormatProvider.GetFormat%2A> method returns either the <xref:System.Globalization.CultureInfo> object or the <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.CultureInfo> object that corresponds to the current culture is used.



## Examples
 The following example demonstrates the <xref:System.DateTime.ParseExact%2A> method.

## Remarks
 The <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method parses the string representation of a date, which must be in a format defined by the `format` parameter. It also requires that the date and time elements in `s` appear in the order specified by `format`. If `s` does not match the pattern of the `format` parameter, with any variations defined by the `style` parameter, the method throws a <xref:System.FormatException>. In contrast, the <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method parses the string representation of a date in any one of the formats recognized by the format provider's <xref:System.Globalization.DateTimeFormatInfo> object. The <xref:System.DateTime.Parse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method also allows the date and time elements in `s` to appear in any order.

 If the `s` parameter contains only a time and no date, the current date is used unless the `style` parameter includes the <xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault?displayProperty=nameWithType> flag, in which case the default date (`DateTime.Date.MinValue`) is used. If the `s` parameter contains only a date and no time, midnight (00:00:00) is used. The `style` parameter also determines whether the `s` parameter can contain leading, inner, or trailing white space characters.

 If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType>, or by using the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> and <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flags, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If `s` contains time zone information, the time is converted to local time, if necessary, and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType> flag to not convert Coordinated Universal Time (UTC) to a local time and to set the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.

 The `format` parameter defines the required pattern of the `s` parameter. It can consist of either one or more custom format specifiers from the [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings) table, or a single standard format specifier, which identifies a predefined pattern, from the [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings) table.

 If you do not use date or time separators in a custom format pattern, use the invariant culture for the `provider` parameter and the widest form of each custom format specifier. For example, if you want to specify hours in the pattern, specify the wider form, "HH", instead of the narrower form, "H".

> [!NOTE]
>  Rather than requiring that `s` conform to a single format for the parse operation to succeed, you can call the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method and specify multiple permitted formats. This makes the parse operation more likely to succeed.

 The `styles` parameter includes one or more members of the <xref:System.Globalization.DateTimeStyles> enumeration that determine whether and where white space not defined by `format` can appear in `s` and that control the precise behavior of the parse operation. The following table describes how each member of the <xref:System.Globalization.DateTimeStyles> enumeration affects the operation of the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> method.

|DateTimeStyles member|Description|
|---------------------------|-----------------|
|<xref:System.Globalization.DateTimeStyles.AdjustToUniversal>|Parses `s` and, if necessary, converts it to UTC. If `s` includes a time zone offset, or if `s` contains no time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, the method parses the string, calls <xref:System.DateTime.ToUniversalTime%2A> to convert the returned <xref:System.DateTime> value to UTC, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If `s` indicates that it represents UTC, or if `s` does not contain time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> flag, the method parses the string, performs no time zone conversion on the returned <xref:System.DateTime> value, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. In all other cases, the flag has no effect.|
|<xref:System.Globalization.DateTimeStyles.AllowInnerWhite>|Specifies that white space not defined by `format` can appear between any individual date or time element.|
|<xref:System.Globalization.DateTimeStyles.AllowLeadingWhite>|Specifies that white space not defined by `format` can appear at the beginning of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowTrailingWhite>|Specifies that white space not defined by `format` can appear at the end of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces>|Specifies that `s` may contain leading, inner, and trailing white spaces not defined by `format`.|
|<xref:System.Globalization.DateTimeStyles.AssumeLocal>|Specifies that if `s` lacks any time zone information, it is assumed to represent a local time. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.AssumeUniversal>|Specifies that if `s` lacks any time zone information, it is assumed to represent UTC. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the method converts the returned <xref:System.DateTime> value from UTC to local time and sets its <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault>|If `s` contains time without date information, the date of the return value is set to `DateTime.MinValue.Date`.|
|<xref:System.Globalization.DateTimeStyles.None>|The `s` parameter is parsed using default values. No white space other than that present in `format` is allowed. If `s` lacks a date component, the date of the returned <xref:System.DateTime> value is set to 1/1/0001. If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. If time zone information is present in `s`, the time is converted to local time and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.RoundtripKind>|For strings that contain time zone information, tries to prevent the conversion to a <xref:System.DateTime> value date and time with its <xref:System.DateTime.Kind%2A> property set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This flag primarily prevents the conversion of UTC times to local times.|

 The particular date and time symbols and strings (such as the names of the days of the week in a particular language) used in `s` are defined by the `provider` parameter, as is the precise format of `s` if `format` is a standard format specifier string. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture used to interpret `s`. The <xref:System.Globalization.DateTimeFormatInfo> object returned by its <xref:System.Globalization.CultureInfo.DateTimeFormat%2A> property defines the symbols and formatting in `s`.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom <xref:System.IFormatProvider> implementation whose <xref:System.IFormatProvider.GetFormat%2A> method returns either the <xref:System.Globalization.CultureInfo> object or the <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.CultureInfo> object that corresponds to the current culture is used.



## Examples
 The following example demonstrates the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%29> method. Note that the string " 5/01/2009 8:30 AM" cannot be parsed successfully when the `styles` parameter equals <xref:System.Globalization.DateTimeStyles.None?displayProperty=nameWithType> because leading spaces are not allowed by `format`. Additionally, the string "5/01/2009 09:00" cannot be parsed successfully with a `format` of "MM/dd/yyyyhh:mm" because the date string does not precede the month number with a leading zero, as `format` requires.

## Remarks
 The <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method parses the string representation of a date that matches any one of the patterns assigned to the `formats` parameter. If the string `s` does not match any one of these patterns with any of the variations defined by the `styles` parameter, the method throws a <xref:System.FormatException>. Aside from comparing `s` to multiple formatting patterns, rather than to a single formatting pattern, this overload behaves identically to the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method.

 The `s` parameter contains the date and time to parse. If the `s` parameter contains only a time and no date, the current date is used unless the `style` parameter includes the <xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault?displayProperty=nameWithType> flag, in which case the default date (`DateTime.Date.MinValue`) is used. If the `s` parameter contains only a date and no time, midnight (00:00:00) is used. The `style` parameter also determines whether the `s` parameter can contain leading, inner, or trailing white space characters other than those permitted by one of the format strings in `formats`.

 If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType>, or by using the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> and <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flags, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If `s` contains time zone information, the time is converted to local time, if necessary, and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType> flag to not convert Coordinated Universal Time (UTC) to a local time and set the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.

 The `formats` parameter contains an array of patterns, one of which `s` must match exactly if the parse operation is to succeed. The patterns in the `formats` parameter consists of one or more custom format specifiers from the [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings) table, or a single standard format specifier, which identifies a predefined pattern, from the [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings) table.

 If you do not use date or time separators in a custom format pattern, use the invariant culture for the `provider` parameter and the widest form of each custom format specifier. For example, if you want to specify hours in the pattern, specify the wider form, "HH", instead of the narrower form, "H".

 The `styles` parameter includes one or more members of the <xref:System.Globalization.DateTimeStyles> enumeration that determine whether and where white space not defined by `format` can appear in `s` and that control the precise behavior of the parse operation. The following table describes how each member of the <xref:System.Globalization.DateTimeStyles> enumeration affects the operation of the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29> method.

|DateTimeStyles member|Description|
|---------------------------|-----------------|
|<xref:System.Globalization.DateTimeStyles.AdjustToUniversal>|Parses `s` and, if necessary, converts it to UTC. If `s` includes a time zone offset, or if `s` contains no time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, the method parses the string, calls <xref:System.DateTime.ToUniversalTime%2A> to convert the returned <xref:System.DateTime> value to UTC, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If `s` indicates that it represents UTC, or if `s` does not contain time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> flag, the method parses the string, performs no time zone conversion on the returned <xref:System.DateTime> value, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. In all other cases, the flag has no effect.|
|<xref:System.Globalization.DateTimeStyles.AllowInnerWhite>|Specifies that white space not defined by `format` can appear between any individual date or time element.|
|<xref:System.Globalization.DateTimeStyles.AllowLeadingWhite>|Specifies that white space not defined by `format` can appear at the beginning of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowTrailingWhite>|Specifies that white space not defined by `format` can appear at the end of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces>|Specifies that `s` may contain leading, inner, and trailing white spaces not defined by `format`.|
|<xref:System.Globalization.DateTimeStyles.AssumeLocal>|Specifies that if `s` lacks any time zone information, it is assumed to represent a local time. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.AssumeUniversal>|Specifies that if `s` lacks any time zone information, it is assumed to represent UTC. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the method converts the returned <xref:System.DateTime> value from UTC to local time and sets its <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault>|If `s` contains time without date information, the date of the return value is set to `DateTime.MinValue.Date`.|
|<xref:System.Globalization.DateTimeStyles.None>|The `s` parameter is parsed using default values. No white space other than that present in `format` is allowed. If `s` lacks a date component, the date of the returned <xref:System.DateTime> value is set to 1/1/0001. If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. If time zone information is present in `s`, the time is converted to local time and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.RoundtripKind>|For strings that contain time zone information, tries to prevent the conversion to a date and time with its <xref:System.DateTime.Kind%2A> property set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This flag primarily prevents the conversion of UTC times to local times.|

 The particular date and time symbols and strings (such as the names of the days of the week in a particular language) used in `s` are defined by the `provider` parameter, as is the precise format of `s` if `format` is a standard format specifier string. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture used to interpret `s`. The <xref:System.Globalization.DateTimeFormatInfo> object returned by its <xref:System.Globalization.CultureInfo.DateTimeFormat%2A> property defines the symbols and formatting in `s`.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom <xref:System.IFormatProvider> implementation whose <xref:System.IFormatProvider.GetFormat%2A> method returns either the <xref:System.Globalization.CultureInfo> object or the <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.CultureInfo> object that corresponds to the current culture is used.



## Examples
 The following example uses the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method to ensure that a string in a number of possible formats can be successfully parsed .

## Remarks
 A <xref:System.DateTime> object consists of a Kind field that indicates whether the time value is based on local time, Coordinated Universal Time (UTC), or neither, and a Ticks field that contains a time value measured in 100-nanosecond ticks. The <xref:System.DateTime.SpecifyKind%2A> method creates a new <xref:System.DateTime> object using the specified `kind` parameter and the original time value.

> [!IMPORTANT]
>  The returned <xref:System.DateTime> value does not represent the same instant in time as the `value` parameter, and <xref:System.DateTime.SpecifyKind%2A> is not a time zone conversion method. Instead, it leaves the time specified by the `value` parameter unchanged, and sets the <xref:System.DateTime.Kind%2A> property to `kind`. For information about time zone conversions, see [Converting Times Between Time Zones](/dotnet/standard/datetime/converting-between-time-zones).

 The <xref:System.DateTime.SpecifyKind%2A> method is useful in interoperability scenarios where you receive a <xref:System.DateTime> object with an unspecified Kind field, but you can determine by independent means that the Ticks field represents local time or UTC.

## Examples
 The following example uses the <xref:System.DateTime.SpecifyKind%2A> method to demonstrate how the <xref:System.DateTime.Kind%2A> property influences the <xref:System.DateTime.ToLocalTime%2A> and <xref:System.DateTime.ToUniversalTime%2A> conversion methods.

## Remarks
 The <xref:System.DateTime.Subtract%28System.DateTime%29> method determines the difference between two dates. To subtract a time interval from the current instance, call the <xref:System.DateTime.Subtract%28System.TimeSpan%29> method. To subtract a particular time interval from the current instance, call the method that adds that time interval to the current date, and supply a negative value as the method argument. For example, to subtract two months from the current date, call the <xref:System.DateTime.AddMonths%28System.Int32%29> method with a value of -2.

 If the date and time of the current instance is earlier than `value`, the method returns a <xref:System.TimeSpan> object that represents a negative time span. That is, the value of all of its non-zero properties (such as <xref:System.TimeSpan.Days%2A> or <xref:System.TimeSpan.Ticks%2A>) is negative.

 The <xref:System.DateTime.Subtract%28System.DateTime%29> method does not consider the value of the <xref:System.DateTime.Kind%2A> property of the two <xref:System.DateTime> values when performing the subtraction. Before subtracting <xref:System.DateTime> objects, ensure that the objects represent times in the same time zone. Otherwise, the result will include the difference between time zones.

> [!NOTE]
>  The <xref:System.DateTimeOffset.Subtract%28System.DateTimeOffset%29?displayProperty=nameWithType> method does consider the difference between time zones when performing the subtraction.



## Examples
 The following example demonstrates the <xref:System.DateTime.Subtract%2A> method and the subtraction operator.

## Remarks
 The <xref:System.DateTime.Subtract%28System.TimeSpan%29> method returns the date that is a specified time interval difference from the current instance. To determine the time interval between two dates, call the <xref:System.DateTime.Subtract%28System.DateTime%29> method. To subtract a particular time interval from the current instance, call the method that adds that time interval to the current date, and supply a negative value as the method argument. For example, to subtract two months from the current date, call the <xref:System.DateTime.AddMonths%28System.Int32%29> method with a value of -2.

 This method does not change the value of this <xref:System.DateTime>. Instead, it returns a new <xref:System.DateTime> whose value is the result of this operation.

 Ordinarily, the <xref:System.DateTime.Subtract%28System.TimeSpan%29?displayProperty=nameWithType> method subtracts a <xref:System.TimeSpan> object that represents a positive time span and returns a <xref:System.DateTime> value that is earlier than the date and time of the current instance. However, if the <xref:System.TimeSpan> object represents a negative time span, the <xref:System.DateTime.Subtract%28System.TimeSpan%29?displayProperty=nameWithType> method returns a <xref:System.DateTime> value that is later than the date and time of the current instance.

 The <xref:System.DateTime.Subtract%28System.TimeSpan%29?displayProperty=nameWithType> method allows you to subtract a time interval that consists of more than one unit of time (such as a given number of hours and a given number of minutes). To subtract a single unit of time (such as years, months, or days) from the <xref:System.DateTime> instance, you can pass a negative numeric value as a parameter to any of the following methods:

-   <xref:System.DateTime.AddYears%2A>, to subtract a specific number of years from the current date and time instance.

-   <xref:System.DateTime.AddMonths%2A>, to subtract a specific number of months from the current date and time instance.

-   <xref:System.DateTime.AddDays%2A>, to subtract a specific number of days from the current date and time instance.

-   <xref:System.DateTime.AddHours%2A>, to subtract a specific number of hours from the current date and time instance.

-   <xref:System.DateTime.AddMinutes%2A>, to subtract a specific number of minutes from the current date and time instance.

-   <xref:System.DateTime.AddSeconds%2A>, to subtract a specific number of seconds from the current date and time instance.

-   <xref:System.DateTime.AddMilliseconds%2A>, to subtract a specific number of milliseconds from the current date and time instance.

-   <xref:System.DateTime.AddTicks%2A>, to subtract a specific number of ticks from the current date and time instance.



## Examples
 The following example demonstrates the <xref:System.DateTime.Subtract%2A> method and the subtraction operator.

## Remarks
 A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond (see <xref:System.TimeSpan.TicksPerMillisecond>) and 10 million ticks in a second.

The value of this property represents the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight, January 1, 0001 in the Gregorian calendar, which represents <xref:System.DateTime.MinValue>. It does not include the number of ticks that are attributable to leap seconds.
If the DateTime object has its `Kind` property set to `Local`, its ticks represent the time elapsed time since 12:00:00 midnight, January 1, 0001 in the local time as specified by the current time zone setting.
If the `DateTime` object has its `Kind` property set to `Utc`, its ticks represent the time elapsed time since 12:00:00 midnight, January 1, 0001 in the Coordinated Universal Time.
If the `DateTime` object has its `Kind` property set to `Unspecified`, its ticks represent the time elapsed time since 12:00:00 midnight, January 1, 0001 in the unknown time zone.

In general, the ticks represent the time according to the time zone specified by the `Kind` property.


## Examples

 The following example uses the <xref:System.DateTime.Ticks%2A> property to display the number of ticks that have elapsed since the beginning of the twenty-first century and to instantiate a <xref:System.TimeSpan> object. The <xref:System.TimeSpan> object is then used to display the elapsed time using several other time intervals.

## Remarks
 Unlike the <xref:System.DateTime.Date%2A> property. which returns a <xref:System.DateTime> value that represents a date without its time component, the <xref:System.DateTime.TimeOfDay%2A> property returns a <xref:System.TimeSpan> value that represents a  <xref:System.DateTime> value's time component.

 If you want to display the time of day or retrieve the string representation of the time of day of a <xref:System.DateTime> value, you can instead call an overload of the <xref:System.DateTime.ToString%2A> method that has a `format` parameter or use the [composite formatting](/dotnet/standard/base-types/composite-formatting) feature with the "t" or "T" standard format string.



## Examples
 The following example displays the value of the <xref:System.DateTime.TimeOfDay%2A> property for an array of <xref:System.DateTime> values. It also contrasts the return value with the string returned by the "t" standard format string in a composite formatting operation.

## Remarks
 Starting with the .NET Framework version 2.0, the return value is a <xref:System.DateTime> whose <xref:System.DateTime.Kind%2A> property returns <xref:System.DateTimeKind.Local>.

 Because it returns the current date without the current time, the <xref:System.DateTime.Today%2A> property is suitable for use in applications that work with dates only. For details, see [Choosing Between DateTime, DateTimeOffset, TimeSpan, and TimeZoneInfo](/dotnet/standard/datetime/choosing-between-datetime). In contrast, the <xref:System.DateTime.TimeOfDay%2A> property returns the current time without the current date, and the <xref:System.DateTime.Now%2A> property returns both the current date and the current time.



## Examples
 The following example uses the <xref:System.DateTime.Date%2A> property to retrieve the current date. It also illustrates how a <xref:System.DateTime> value can be formatted using some of the standard date and time format strings. Note that the output produced by the third call to the <xref:System.DateTime.ToString%28System.String%29> method uses the g format specifier to include the time component, which is zero.

## Remarks
 A Windows file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC). Windows uses a file time to record when an application creates, accesses, or writes to a file.

 The <xref:System.DateTime.ToFileTime%2A> method uses the <xref:System.DateTime.Kind%2A> property to determine whether the current <xref:System.DateTime> object is a local time, a UTC time, or an unspecified kind of time which is treated as a local time.



## Examples
 The following example demonstrates the <xref:System.DateTime.ToFileTime%2A> method.

          <para>Ordinarily, the <see cref="M:System.DateTime.FromFileTime(System.Int64)" /> method restores a <see cref="T:System.DateTime" /> value that was saved by the <see cref="M:System.DateTime.ToFileTime" /> method. However, the two values may differ under the following conditions:

-   If the serialization and deserialization of the <see cref="T:System.DateTime" /> value occur in different time zones. For example, if a <see cref="T:System.DateTime" /> value with a time of 12:30 P.M. in the U.S. Eastern Time zone is serialized, and then deserialized in the U.S. Pacific Time zone, the original value of 12:30 P.M. is adjusted to 9:30 A.M. to reflect the difference between the two time zones.

-   If the <see cref="T:System.DateTime" /> value that is serialized represents an invalid time in the local time zone. In this case, the <see cref="M:System.DateTime.ToFileTime" /> method adjusts the restored <see cref="T:System.DateTime" /> value so that it represents a valid time in the local time zone.

     For example, the transition from standard time to daylight saving time occurs in the U.S. Pacific Time zone on March 14, 2010, at 2:00 A.M., when the time advances by one hour, to 3:00 A.M. This hour interval is an invalid time, that is, a time interval that does not exist in this time zone. The following example shows that when a time that falls within this range is converted to a long integer value by the <see cref="M:System.DateTime.ToFileTime" /> method and is then restored by the <see cref="M:System.DateTime.FromFileTime(System.Int64)" /> method, the original value is adjusted to become a valid time. You can determine whether a particular date and time value may be subject to modification by passing it to the <see cref="M:System.TimeZoneInfo.IsInvalidTime(System.DateTime)" /> method, as the example illustrates.

## Remarks
 A Windows file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC). Windows uses a file time to record when an application creates, accesses, or writes to a file.

 The <xref:System.DateTime.ToFileTimeUtc%2A> method uses the <xref:System.DateTime.Kind%2A> property to determine whether the current <xref:System.DateTime> object is a local time, a UTC time, or an unspecified kind of time which is treated as a UTC time. If it is a local time, it converts the time to UTC before performing the conversion to a Windows file time.

## Remarks
 The local time is equal to the Coordinated Universal Time (UTC) time plus the UTC offset. For more information about the UTC offset, see <xref:System.TimeZoneInfo.GetUtcOffset%2A?displayProperty=nameWithType>. The conversion also takes into account the daylight saving time rule that applies to the time represented by the current <xref:System.DateTime> object.

> [!IMPORTANT]
>  On Windows XP systems, the <xref:System.DateTime.ToLocalTime%2A> method recognizes only the current adjustment rule when converting from UTC to local time. As a result, conversions for periods before the current adjustment rule came into effect may not accurately reflect the difference between UTC and local time.

 Starting with the .NET Framework version 2.0, the value returned by the <xref:System.DateTime.ToLocalTime%2A> method is determined by the <xref:System.DateTime.Kind%2A> property of the current <xref:System.DateTime> object. The following table describes the possible results.

|Kind|Results|
|----------|-------------|
|<xref:System.DateTimeKind.Utc>|This instance of <xref:System.DateTime> is converted to local time.|
|<xref:System.DateTimeKind.Local>|No conversion is performed.|
|<xref:System.DateTimeKind.Unspecified>|This instance of <xref:System.DateTime> is assumed to be a UTC time, and the conversion is performed as if <xref:System.DateTime.Kind%2A> were <xref:System.DateTimeKind.Utc>.|

> [!NOTE]
>  The <xref:System.DateTime.ToLocalTime%2A> method converts a <xref:System.DateTime> value from UTC to local time. To convert the time in any designated time zone to local time, use the <xref:System.TimeZoneInfo.ConvertTime%2A?displayProperty=nameWithType> method.

 The value returned by the conversion is a <xref:System.DateTime> whose <xref:System.DateTime.Kind%2A> property always returns <xref:System.DateTimeKind.Local>. Consequently, a valid result is returned even if <xref:System.DateTime.ToLocalTime%2A> is applied repeatedly to the same <xref:System.DateTime>.



## Examples
 The following example demonstrates the <xref:System.DateTime.ToLocalTime%2A> method. Note that the exact output depends on the current culture and the local time zone of the system on which it is run.

 The following example uses the <xref:System.DateTime.SpecifyKind%2A> method to demonstrate how the <xref:System.DateTime.Kind%2A> property influences the <xref:System.DateTime.ToLocalTime%2A> and <xref:System.DateTime.ToUniversalTime%2A> conversion methods.

        </remarks>
        <block subset="none" type="usage">
          <para>You can use the <see cref="M:System.DateTime.ToLocalTime" /> method to restore a local date and time value that was converted to UTC by the <see cref="M:System.DateTime.ToUniversalTime" /> or <see cref="M:System.DateTime.FromFileTimeUtc(System.Int64)" /> method. However, if the original time represents an invalid time in the local time zone, it will not match the restored value. When the <see cref="M:System.DateTime.ToLocalTime" /> method converts a time from UTC to the local time zone, it also adjusts the time so that is valid in the local time zone.

 For example, the transition from standard time to daylight saving time occurs in the U.S. Pacific Time zone on March 14, 2010, at 2:00 A.M., when the time advances by one hour, to 3:00 A.M. This hour interval is an invalid time, that is, a time interval that does not exist in this time zone. The following example shows that when a time that falls within this range is converted to UTC by the <see cref="M:System.DateTime.ToUniversalTime" /> method and is then restored by the <see cref="M:System.DateTime.ToLocalTime" /> method, the original value is adjusted to become a valid time. You can determine whether a particular date and time value may be subject to modification by passing it to the <see cref="M:System.TimeZoneInfo.IsInvalidTime(System.DateTime)" /> method, as the example illustrates.

The return value is identical to the value returned by specifying the "T" [standard date and time format string](/dotnet/standard/base-types/standard-date-and-time-format-strings) with the <xref:System.DateTime.ToString%28System.String%29> method.

> [!NOTE]

It reflects the pattern defined by the current culture's <xref:System.Globalization.DateTimeFormatInfo.LongTimePattern%2A?displayProperty=nameWithType> property. For example, for the en-US culture, the standard long time pattern is "h:mm:ss tt"; for the de-DE culture, it is "HH:mm:ss"; for the ja-JP culture, it is "H:mm:ss". Note that its value can vary depending on the .NET implementation and its version, the operating system and its version, and user customization.

        <remarks>
          <format type="text/markdown"><![CDATA[

## Remarks
 An OLE Automation date is implemented as a floating-point number whose integral component is the number of days before or after midnight, 30 December 1899, and whose fractional component represents the time on that day divided by 24. For example, midnight, 31 December 1899 is represented by 1.0; 6 A.M., 1 January 1900 is represented by 2.25; midnight, 29 December 1899 is represented by -1.0; and 6 A.M., 29 December 1899 is represented by -1.25.

 The base OLE Automation Date is midnight, 30 December 1899. The minimum OLE Automation date is midnight, 1 January 0100. The maximum OLE Automation Date is the same as <xref:System.DateTime.MaxValue?displayProperty=nameWithType>, the last moment of 31 December 9999.

 The <xref:System.DateTime.ToOADate%2A> method throws an <xref:System.OverflowException> if the current instance represents a date that is later than <xref:System.DateTime.MaxValue> and earlier than midnight on January1, 0100. However, if the value of the current instance is <xref:System.DateTime.MinValue>, the method returns 0.

## Remarks
 The value of the current <xref:System.DateTime> object is formatted using the pattern defined by the <xref:System.Globalization.DateTimeFormatInfo.ShortDatePattern%2A?displayProperty=nameWithType> property associated with the current culture. The return value is identical to the value returned by specifying the "d" [standard DateTime format string](/dotnet/standard/base-types/standard-date-and-time-format-strings) with the <xref:System.DateTime.ToString%28System.String%29> method.

> [!NOTE]
>  The string returned by the <xref:System.DateTime.ToShortDateString%2A> method is culture-sensitive. It reflects the pattern defined by the current culture's <xref:System.Globalization.DateTimeFormatInfo.ShortDatePattern?displayProperty=nameWithType> property. For example, for the en-US culture, the standard short date pattern is "M/d/yyyy"; for the de-DE culture, it is "dd.MM.yyyy"; for the ja-JP culture, it is "yyyy/MM/dd". Note that its value can vary depending on the .NET implementation and its version, the operating system and its version, and user customization.

## Examples
 The following example demonstrates the <xref:System.DateTime.ToShortDateString%2A> method. It also shows that the result of calling the <xref:System.DateTime.ToShortDateString%2A> method is identical to calling the <xref:System.DateTime.ToString%28System.String%29?displayProperty=nameWithType> method with "d" as the format parameter.

## Remarks
 The value of the current <xref:System.DateTime> object is formatted using the general date and time format specifier ('G'). To format it using a specific date and time format specifier, call the <xref:System.DateTime.ToString%28System.String%29> method. To format it using the general date and time format specifier ('G') for a specific culture, call the <xref:System.DateTime.ToString%28System.IFormatProvider%29> method. To format it using a specific date and time format specifier and the conventions of a specific culture, call the <xref:System.DateTime.ToString%28System.String%2CSystem.IFormatProvider%29> method.

 This method uses formatting information derived from the current culture. In particular, it combines the custom format strings returned by the <xref:System.Globalization.DateTimeFormatInfo.ShortDatePattern%2A> and <xref:System.Globalization.DateTimeFormatInfo.LongTimePattern%2A> properties of the <xref:System.Globalization.DateTimeFormatInfo> object returned by the `Thread.CurrentThread.CurrentCulture.DateTimeFormat` property. For more information, see <xref:System.Globalization.CultureInfo.CurrentCulture%2A?displayProperty=nameWithType>. Other overloads of the <xref:System.DateTime.ToString%2A> method enable you to specify the culture whose formatting to use and to define the output pattern of the <xref:System.DateTime> value.

## Examples

The following example illustrates how the string representation of a <xref:System.DateTime> value returned by the <xref:System.DateTime.ToString> method depends on the thread current culture. It changes the current culture to en-US, fr-FR, and ja-JP, and in each case calls the <xref:System.DateTime.ToString> method to return the string representation of a date and time value using that culture.

## Remarks
 The value of the current <xref:System.DateTime> object is formatted using the general date and time format specifier ('G'), which formats output using the short date pattern and the long time pattern.

 The format of the short date and long time pattern is defined by the `provider` parameter. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture whose formatting conventions are to be reflected in the returned string. The <xref:System.Globalization.DateTimeFormatInfo> object returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat%2A?displayProperty=nameWithType> property defines the formatting of the returned string.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom object that implements the <xref:System.IFormatProvider> interface. Its <xref:System.IFormatProvider.GetFormat%2A> method returns a <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.DateTimeFormatInfo> object associated with the current culture is used. For more information, see <xref:System.Globalization.CultureInfo.CurrentCulture%2A?displayProperty=nameWithType>.



## Examples
 The following example displays the string representation of a date and time using <xref:System.Globalization.CultureInfo> objects that represent five different cultures.

## Remarks
 The <xref:System.DateTime.ToString%28System.String%29> method returns the string representation of a date and time value in a specific format that uses the formatting conventions of the current culture; for more information, see <xref:System.Globalization.CultureInfo.CurrentCulture%2A?displayProperty=nameWithType>.

 The `format` parameter should contain either a single format specifier character (see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings)) or a custom format pattern (see [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings)) that defines the format of the returned string. If `format` is `null` or an empty string, the general format specifier, 'G', is used.

 Some uses of this method include:

-   Getting a string that displays the date and time in the current culture's short date and time format. To do this, you use the "G" format specifier.

-   Getting a string that contains only the month and year. To do this, you use the "MM/yyyy" format string. The format string uses the current culture's date separator.

-   Getting a string that contains the date and time in a specific format. For example, the "MM/dd/yyyyHH:mm" format string displays the date and time string in a fixed format such as "19//03//2013 18:06". The format string uses "/" as a fixed date separator regardless of culture-specific settings.

-   Getting a date in a condensed format that could be used for serializing a date string. For example, the "yyyyMMdd" format string displays a four-digit year followed by a two-digit month and a two-digit day with no date separator.

 The following example uses these three format strings to display a date and time value by using the conventions of the en-US and fr-FR cultures.

## Remarks
 The `format` parameter can contain either a single format specifier character (see [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings)) or a custom format pattern (see [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings)). If `format` is `null` or an empty string (""), the standard format specifier, "G", is used.

 The `provider` parameter defines the pattern that corresponds to the standard format specifiers, as well as the symbols and names of date and time components. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture whose formatting conventions are to be reflected in the returned string. The <xref:System.Globalization.DateTimeFormatInfo> object returned by the <xref:System.Globalization.CultureInfo.DateTimeFormat%2A?displayProperty=nameWithType> property defines the formatting of the returned string.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom object that implements the <xref:System.IFormatProvider> interface. Its <xref:System.IFormatProvider.GetFormat%2A> method returns a <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.DateTimeFormatInfo> associated with the current culture is used. For more information, see <xref:System.Globalization.CultureInfo.CurrentCulture%2A?displayProperty=nameWithType>.



## Examples
 The following example uses each of the standard date time format strings to display the string representation of a date and time for four different cultures.

## Remarks
 The Coordinated Universal Time (UTC) is equal to the local time minus the UTC offset. For more information about the UTC offset, see <xref:System.TimeZoneInfo.GetUtcOffset%2A?displayProperty=nameWithType>. The conversion also takes into account the daylight saving time rule that applies to the time represented by the current <xref:System.DateTime> object.

> [!IMPORTANT]
>  On Windows XP systems, the <xref:System.DateTime.ToUniversalTime%2A> method recognizes only the current adjustment rule when converting from local time to UTC. As a result, conversions for periods before the current adjustment rule came into effect may not accurately reflect the difference between local time and UTC.

 Starting with the .NET Framework version 2.0, the value returned by the <xref:System.DateTime.ToUniversalTime%2A> method is determined by the <xref:System.DateTime.Kind%2A> property of the current <xref:System.DateTime> object. The following table describes the possible results.

|Kind|Results|
|----------|-------------|
|<xref:System.DateTimeKind.Utc>|No conversion is performed.|
|<xref:System.DateTimeKind.Local>|The current <xref:System.DateTime> object is converted to UTC.|
|<xref:System.DateTimeKind.Unspecified>|The current <xref:System.DateTime> object is assumed to be a local time, and the conversion is performed as if <xref:System.DateTime.Kind%2A> were <xref:System.DateTimeKind.Local>.|

> [!NOTE]
>  The <xref:System.DateTime.ToUniversalTime%2A> method converts a <xref:System.DateTime> value from local time to UTC. To convert the time in a non-local time zone to UTC, use the <xref:System.TimeZoneInfo.ConvertTimeToUtc%28System.DateTime%2CSystem.TimeZoneInfo%29?displayProperty=nameWithType> method. To convert a time whose offset from UTC is known, use the <xref:System.DateTimeOffset.ToUniversalTime%2A> method.

 If the date and time instance value is an ambiguous time, this method assumes that it is a standard time. (An ambiguous time is one that can map either to a standard time or to a daylight saving time in the local time zone) If the date and time instance value is an invalid time, this method simply subtracts the local time from the local time zone's UTC offset to return UTC. (An invalid time is one that does not exist because of the application of daylight saving time adjustment rules.)



## Examples
 The following example demonstrates the <xref:System.DateTime.ToUniversalTime%2A> method.

 The following example uses the <xref:System.DateTime.SpecifyKind%2A> method to demonstrate how the <xref:System.DateTime.Kind%2A> property influences the <xref:System.DateTime.ToLocalTime%2A> and <xref:System.DateTime.ToUniversalTime%2A> conversion methods.

        </remarks>
        <block subset="none" type="usage">
          <para>The <see cref="M:System.DateTime.ToUniversalTime" /> method is sometimes used to convert a local time to UTC. The <see cref="M:System.DateTime.ToLocalTime" /> method is then called to restore the original local time. However, if the original time represents an invalid time in the local time zone, the two local time values will not be equal. For additional information and an example, see the <see cref="M:System.DateTime.ToLocalTime" /> method.

 On Windows XP systems, the <see cref="M:System.DateTime.ToUniversalTime" /> method recognizes only the current adjustment rule for the local time zone, which it applies to all dates, including down-level dates (that is, dates that are earlier than the starting date of the current adjustment rule). Applications running on Windows XP that require historically accurate local date and time calculations must work around this behavior by using the <see cref="M:System.TimeZoneInfo.FindSystemTimeZoneById(System.String)" /> method to retrieve a <see cref="T:System.TimeZoneInfo" /> object that corresponds to the local time zone and calling its <see cref="M:System.TimeZoneInfo.ConvertTimeToUtc(System.DateTime,System.TimeZoneInfo)" /> method.

 The following example illustrates the difference between the <see cref="M:System.DateTime.ToUniversalTime" /> and <see cref="M:System.TimeZoneInfo.ConvertTimeToUtc(System.DateTime,System.TimeZoneInfo)" /> methods on a Windows XP system in the U.S. Pacific Time zone. The first two method calls apply the current time zone adjustment rule (which went into effect in 2007) to a date in 2006. The current adjustment rule provides for the transition to daylight saving time on the second Sunday of March; the previous rule, which was in effect in 2006, provided for the transition to daylight saving time to occur on the first Sunday of April. Only the third method call accurately performs this historical date and time conversion.

## Remarks
 The <xref:System.DateTime.TryParse%28System.String%2CSystem.DateTime%40%29?displayProperty=nameWithType> method is similar to the <xref:System.DateTime.Parse%28System.String%29?displayProperty=nameWithType> method, except that the <xref:System.DateTime.TryParse%28System.String%2CSystem.DateTime%40%29> method does not throw an exception if the conversion fails.

 The string `s` is parsed using formatting information in the current <xref:System.Globalization.DateTimeFormatInfo> object, which is supplied implicitly by the current culture.

 This method tries to ignore unrecognized data, if possible, and fills in missing month, day, and year information with the current date. If `s` contains only a date and no time, this method assumes the time is 12:00 midnight. If `s` includes a date component with a two-digit year, it is converted to a year in the current culture's current calendar based on the value of the <xref:System.Globalization.Calendar.TwoDigitYearMax%2A?displayProperty=nameWithType> property. Any leading, inner, or trailing white space character in `s` is ignored. The date and time can be bracketed with a pair of leading and trailing NUMBER SIGN characters ('#', U+0023), and can be trailed with one or more NULL characters (U+0000).

 Because the <xref:System.DateTime.TryParse%28System.String%2CSystem.DateTime%40%29?displayProperty=nameWithType> method tries to parse the string representation of a date and time using the formatting rules of the current culture, trying to parse a particular string across different cultures can either fail or return different results. If a specific date and time format will be parsed across different locales, use the <xref:System.DateTime.TryParse%28System.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29?displayProperty=nameWithType> method or one of the overloads of the <xref:System.DateTime.TryParseExact%2A> method and provide a format specifier.

 If `s` is the string representation of a leap day in a leap year in the current calendar, the method parses `s` successfully. If `s` is the string representation of a leap day in a non-leap year in the current culture's current calendar, the parse operation fails and the method returns `false`.

 If `s` contains no time zone information, `result` contains a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType> when the method returns. If the string to be parsed contains time zone information, `result` contains a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType> when the method returns.

## Examples
 The following example passes a number of date and time strings to the <xref:System.DateTime.TryParse%28System.String%2CSystem.DateTime%40%29?displayProperty=nameWithType> method.

## Remarks
 The <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29?displayProperty=nameWithType> method parses the string representation of a date, which must be in the format defined by the `format` parameter. It is similar to the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method, except that the <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29> method does not throw an exception if the conversion fails.

 The `s` parameter contains the date and time to parse and must be in a format defined by the `format` parameter. If date, time, and time zone elements are present in `s`, they must also appear in the order specified by `format`. If `format` defines a date with no time element and the parse operation succeeds, the resulting <xref:System.DateTime> value has a time of midnight (00:00:00). If `format` defines a time with no date element and the parse operation succeeds, the resulting <xref:System.DateTime> value by default has a date of `DateTime.Now.Date`, or it has a date of `DateTime.MinValue.Date` if `styles` includes the <xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault?displayProperty=nameWithType> flag. The `style` parameter determines whether the `s` parameter can contain leading, inner, or trailing white space characters.

 If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType>, or by using the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> and <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flags, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If s contains time zone information, the time is converted to local time, if necessary, and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType> flag to not convert Coordinated Universal Time (UTC) to a local time and set the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.

 The `format` parameter contains a pattern that corresponds to the expected format of the `s` parameter. The pattern in the `format` parameter consists of one or more custom format specifiers from the [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings) table, or a single standard format specifier, which identifies a predefined pattern, from the [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings) table.

 If you do not use date or time separators in a custom format pattern, use the invariant culture for the `provider` parameter and the widest form of each custom format specifier. For example, if you want to specify hours in the pattern, specify the wider form, "HH", instead of the narrower form, "H".

> [!NOTE]
>  Rather than requiring that `s` conform to a single format for the parse operation to succeed, you can call the <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29?displayProperty=nameWithType> method and specify multiple permitted formats. This makes the parse operation more likely to succeed.

 The particular date and time symbols and strings (such as the names of the days of the week in a particular language) used in `s` are defined by the `provider` parameter, as is the precise format of `s` if `format` is a standard format specifier string. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture used to interpret `s`. The <xref:System.Globalization.DateTimeFormatInfo> object returned by its <xref:System.Globalization.CultureInfo.DateTimeFormat%2A> property defines the symbols and formatting in `s`.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom <xref:System.IFormatProvider> implementation whose <xref:System.IFormatProvider.GetFormat%2A> method returns either the <xref:System.Globalization.CultureInfo> object or the <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.CultureInfo> object that corresponds to the current culture is used.

 The `styles` parameter includes one or more members of the <xref:System.Globalization.DateTimeStyles> enumeration that determine whether and where white space not defined by `format` can appear in `s` and that control the precise behavior of the parse operation. The following table describes how each member of the <xref:System.Globalization.DateTimeStyles> enumeration affects the operation of the <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29> method.

|DateTimeStyles member|Description|
|---------------------------|-----------------|
|<xref:System.Globalization.DateTimeStyles.AdjustToUniversal>|Parses `s` and, if necessary, converts it to UTC. If `s` includes a time zone offset, or if `s` contains no time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, the method parses the string, calls <xref:System.DateTime.ToUniversalTime%2A> to convert the returned <xref:System.DateTime> value to UTC, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If `s` indicates that it represents UTC, or if `s` does not contain time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> flag, the method parses the string, performs no time zone conversion on the returned <xref:System.DateTime> value, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. In all other cases, the flag has no effect.|
|<xref:System.Globalization.DateTimeStyles.AllowInnerWhite>|Specifies that white space not defined by `format` can appear between any individual date or time element.|

|<xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces>|Specifies that `s` may contain leading, inner, and trailing white spaces not defined by `format`.|
|<xref:System.Globalization.DateTimeStyles.AssumeLocal>|Specifies that if `s` lacks any time zone information, it is assumed to represent a local time. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.AssumeUniversal>|Specifies that if `s` lacks any time zone information, it is assumed to represent UTC. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the method converts the returned <xref:System.DateTime> value from UTC to local time and sets its <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault>|If `s` contains time without date information, the date of the return value is set to `DateTime.MinValue.Date`.|
|<xref:System.Globalization.DateTimeStyles.None>|The `s` parameter is parsed using default values. No white space other than that present in `format` is allowed. If `s` lacks a date component, the date of the returned <xref:System.DateTime> value is set to 1/1/0001. If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. If time zone information is present in `s`, the time is converted to local time and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.RoundtripKind>|For strings that contain time zone information, tries to prevent the conversion to a <xref:System.DateTime> value with its <xref:System.DateTime.Kind%2A> property set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This flag primarily prevents the conversion of UTC times to local times.|



## Examples
 The following example demonstrates the <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29?displayProperty=nameWithType> method. Note that the string " 5/01/2009 8:30 AM" cannot be parsed successfully when the `styles` parameter equals <xref:System.Globalization.DateTimeStyles.None?displayProperty=nameWithType> because leading spaces are not allowed by `format`. Additionally, the string "5/01/2009 09:00" cannot be parsed successfully with a `format` of "MM/dd/yyyyhh:mm" because the date string does not precede the month number with a leading zero, as `format` requires.

## Remarks
 The <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29?displayProperty=nameWithType> method parses the string representation of a date that matches any one of the patterns assigned to the `formats` parameter. It is like the <xref:System.DateTime.ParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%29?displayProperty=nameWithType> method, except the <xref:System.DateTime.TryParseExact%2A> method does not throw an exception if the conversion fails.

 The `s` parameter contains the date and time to parse. If the `s` parameter contains only a time and no date, the current date is used unless the `style` parameter includes the <xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault?displayProperty=nameWithType> flag, in which case the default date (`DateTime.Date.MinValue`) is used. If the `s` parameter contains only a date and no time, midnight (00:00:00) is used. The `style` parameter also determines whether the `s` parameter can contain leading, inner, or trailing white space characters other than those permitted by one of the format strings in `formats`.

 If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Local?displayProperty=nameWithType>, or by using the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> and <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flags, which returns a <xref:System.DateTime> value whose <xref:System.DateTime.Kind%2A> property is <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If s contains time zone information, the time is converted to local time, if necessary, and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This behavior can be changed by using the <xref:System.Globalization.DateTimeStyles.RoundtripKind?displayProperty=nameWithType> flag to not convert Coordinated Universal Time (UTC) to a local time and set the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.

 The `formats` parameter contains an array of patterns, one of which `s` must match exactly if the parse operation is to succeed. The patterns in the `formats` parameter consist of one or more custom format specifiers from the [Custom Date and Time Format Strings](/dotnet/standard/base-types/custom-date-and-time-format-strings) table, or a single standard format specifier, which identifies a predefined pattern, from the [Standard Date and Time Format Strings](/dotnet/standard/base-types/standard-date-and-time-format-strings) table.

 If you do not use date or time separators in a custom format pattern, use the invariant culture for the `provider` parameter and the widest form of each custom format specifier. For example, if you want to specify hours in the pattern, specify the wider form, "HH", instead of the narrower form, "H".

 The particular date and time symbols and strings (such as the names of the days of the week in a particular language) used in `s` are defined by the `provider` parameter, as is the precise format of `s` if `format` is a standard format specifier string. The `provider` parameter can be any of the following:

-   A <xref:System.Globalization.CultureInfo> object that represents the culture used to interpret `s`. The <xref:System.Globalization.DateTimeFormatInfo> object returned by its <xref:System.Globalization.CultureInfo.DateTimeFormat%2A> property defines the symbols and formatting in `s`.

-   A <xref:System.Globalization.DateTimeFormatInfo> object that defines the format of date and time data.

-   A custom <xref:System.IFormatProvider> implementation whose <xref:System.IFormatProvider.GetFormat%2A> method returns either the <xref:System.Globalization.CultureInfo> object or the <xref:System.Globalization.DateTimeFormatInfo> object that provides formatting information.

 If `provider` is `null`, the <xref:System.Globalization.CultureInfo> object that corresponds to the current culture is used.

 The `styles` parameter includes one or more members of the <xref:System.Globalization.DateTimeStyles> enumeration that determine whether and where white space not defined by `format` can appear in `s` and that control the precise behavior of the parse operation. The following table describes how each member of the <xref:System.Globalization.DateTimeStyles> enumeration affects the operation of the <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%5B%5D%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29> method.

|DateTimeStyles member|Description|
|---------------------------|-----------------|
|<xref:System.Globalization.DateTimeStyles.AdjustToUniversal>|Parses `s` and, if necessary, converts it to UTC. If `s` includes a time zone offset, or if `s` contains no time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeLocal?displayProperty=nameWithType> flag, the method parses the string, calls <xref:System.DateTime.ToUniversalTime%2A> to convert the returned <xref:System.DateTime> value to UTC, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. If `s` indicates that it represents UTC, or if `s` does not contain time zone information but `styles` includes the <xref:System.Globalization.DateTimeStyles.AssumeUniversal?displayProperty=nameWithType> flag, the method parses the string, performs no time zone conversion on the returned <xref:System.DateTime> value, and sets the <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>. In all other cases, the flag has no effect.|
|<xref:System.Globalization.DateTimeStyles.AllowInnerWhite>|Specifies that white space not defined by `format` can appear between any individual date or time element.|
|<xref:System.Globalization.DateTimeStyles.AllowLeadingWhite>|Specifies that white space not defined by `format` can appear at the beginning of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowTrailingWhite>|Specifies that white space not defined by `format` can appear at the end of `s`.|
|<xref:System.Globalization.DateTimeStyles.AllowWhiteSpaces>|Specifies that `s` may contain leading, inner, and trailing white spaces not defined by `format`.|
|<xref:System.Globalization.DateTimeStyles.AssumeLocal>|Specifies that if `s` lacks any time zone information, it is assumed to represent a local time. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> value is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.AssumeUniversal>|Specifies that if `s` lacks any time zone information, it is assumed to represent UTC. Unless the <xref:System.Globalization.DateTimeStyles.AdjustToUniversal?displayProperty=nameWithType> flag is present, the method converts the returned <xref:System.DateTime> value from UTC to local time and sets its <xref:System.DateTime.Kind%2A> property to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.NoCurrentDateDefault>|If `s` contains time without date information, the date of the return value is set to `DateTime.MinValue.Date`.|
|<xref:System.Globalization.DateTimeStyles.None>|The `s` parameter is parsed using default values. No white space other than that present in `format` is allowed. If `s` lacks a date component, the date of the returned <xref:System.DateTime> value is set to 1/1/0001. If `s` contains no time zone information, the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Unspecified?displayProperty=nameWithType>. If time zone information is present in `s`, the time is converted to local time and the <xref:System.DateTime.Kind%2A> property of the returned <xref:System.DateTime> object is set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>.|
|<xref:System.Globalization.DateTimeStyles.RoundtripKind>|For strings that contain time zone information, tries to prevent the conversion to a <xref:System.DateTime> value with its <xref:System.DateTime.Kind%2A> property set to <xref:System.DateTimeKind.Local?displayProperty=nameWithType>. This flag primarily prevents the conversion of UTC times to local times.|



## Examples
 The following example uses the <xref:System.DateTime.TryParseExact%28System.String%2CSystem.String%2CSystem.IFormatProvider%2CSystem.Globalization.DateTimeStyles%2CSystem.DateTime%40%29?displayProperty=nameWithType> method to ensure that a string in a number of possible formats can be successfully parsed .

## Remarks
 The resolution of this property depends on the system timer, which depends on the underlying operating system. It tends to be between 0.5 and 15 milliseconds.

 Starting with the .NET Framework version 2.0, the return value is a <xref:System.DateTime> whose <xref:System.DateTime.Kind%2A> property returns <xref:System.DateTimeKind.Utc?displayProperty=nameWithType>.

 An alternative to using <xref:System.DateTime.UtcNow%2A> is <xref:System.DateTimeOffset.UtcNow%2A?displayProperty=nameWithType>. While the former indicates that a date and time value is Coordinated Universal Time (UTC) by assigning <xref:System.DateTimeKind.Utc?displayProperty=nameWithType> to its <xref:System.DateTime.Kind%2A> property, the latter assigns the date and time value the UTC time's offset (equal to <xref:System.TimeSpan.Zero?displayProperty=nameWithType>).

## Examples
 The following example uses the <xref:System.DateTime.SpecifyKind%2A> method to demonstrate how the <xref:System.DateTime.Kind%2A> property influences the <xref:System.DateTime.ToLocalTime%2A> and <xref:System.DateTime.ToUniversalTime%2A> conversion methods.

## Remarks
 The <xref:System.DateTime.Year%2A> property returns the year of the current instance in the Gregorian calendar. It does not return the year using the default calendar of the current culture. To retrieve the year using a particular calendar, you can call that calendar's `GetYear` method, as the following code shows.
