About Holiday Weave

Holiday Weave helps people coordinate across countries by comparing holiday dates in one monthly view.

Where dates come from

Calendars are generated using python-holidays, an MIT-licensed community-maintained library. This release uses version 0.105, generated October 2, 2026, for 2025–2028. The current release supports 246 countries and territories, not every country worldwide.

Coverage and limitations

We use each country's default calendar with observed dates enabled. Default calendars do not necessarily cover every state, province, municipality, faith, bank, school or employer. Some calendars include country-specific default categories. English names are requested; where translations are unavailable, source names may remain in another language.

Future dates and exceptional government announcements can change. Verify critical plans against the relevant government or institution. This is not an official government calendar.
