ZoneStamp is a timezone converter for events. If you run events with an audience spread across different timezones, ZoneStamp makes it easy to create a shareable "stamp" link for your event's date and time. When a recipient clicks the link, ZoneStamp automatically shows the time in their timezone — no mental math required.
Live site: zonestamp.toolforge.org (also at zonestamp.com)
- Open ZoneStamp and pick the date, time, and timezone of your event.
- Optionally add a name, description, URL, and end time.
- Click Generate Stamp! to get a shareable link and QR code.
- Paste the link in your email, newsletter, or chat — recipients see the time converted to their local timezone.
The stamp link also offers an Add to Calendar button for Google Calendar, Outlook, Office 365, Yahoo, and iCal downloads.

Stamp URLs are portable and self-contained:
https://zonestamp.toolforge.org/{unix-timestamp}
https://zonestamp.toolforge.org/{start-timestamp}/{end-timestamp}?name=Event+Name&description=...
These URLs are stable — they will keep working as long as the site exists. No information is stored by the website, it is all inside the stamp url and/or QR code.
This is the Vue 3 + TypeScript rewrite (branch ng) of the original React app. See docs/technical-design.md for architecture decisions and docs/graphical-design.md for design system docs.
