📅 Thai & Buddhist Calendar ปฏิทิน

Thailand runs on two calendars at once. Everyday dates are Gregorian, but the year is counted in the Buddhist Era (พ.ศ., the Gregorian year + 543), and the holy days follow the moon. Switch views to see each one.

Covers 2026–2028 (พ.ศ. 2569–2571). Wan Phra dates come from the published Thai holy-day calendar, and the lunar holidays are worked out from them. 2028's official public holidays haven't been announced yet, and when a holiday falls on a weekend Thailand often adds a substitute day off, which isn't shown here.
