A date looks wrong

Report a wrong date. Please include the page address, the date you expected and where it comes from (an official calendar, a temple or institution, a government notice).

When a correction is confirmed, the date is fixed within 48 hours: the pack keeps the same entry, its version goes up by one, and the change is noted. Calendar files you already downloaded update when you download them again; subscribed calendars update on their own.

Calendar packs and sources

Questions about a pack, or a source we should add: write to contact@whatdate.app. Each pack page lists the sources behind every date.
