Where it is heading
- Calendars for more countries, with official holiday data per country.
- More historical and future years for every covered country.
- Locale-based routes (such as /en and /ja) so each audience gets the calendar in its own language.
Accuracy
Holiday dates are taken from official government documents and updated whenever amendments are published. Some dates — notably Islamic holidays — can change on short notice by government decision, so always check the last-updated date shown on each page and the official sources listed on the data-sources page.
