Systematic errors in the Date column

[paulcdry]

Hi,

I have downloaded all the datasets for the 16 German Landesparlamente and I found some issues with the Date variable. Some speeches seem to have been consistently assigned the wrong dates. For instance, Niedersachsen's date stops at 13.04.2007. However, looking into the speeches from 2007, you find that they were actually held in 2022. I found that all the dates from Niedersachsen from at least ~1992 onwards are lagged, and the difference increases with time.

I found similar issues in the data of Hessen and Sachsen-Anhalt, but the lags are not as big and they seem to be constrained to specific date intervals (from about a year to a year and a half). In Sachsen-Anhalt, the issue is located in period 6, sessions 1-63. All the dates from those speeches have a lagged date.

Have you got any idea what those errors could be due to and how to identify them? Any help would be appreciated.

Best,
Paul

Hi!

Thank you for the information! I will look into this soon. We are planning to create a new version of the data set from scratch with improved meta data and updates until 2025 soon, but I am currently busy with other projects and did not get to it yet. When I do, I will look into the dates and why they are classified incorrectly.
