Thailand Calendar

Thailand uses Indochina Time (UTC+7) with no daylight saving. Official documents count years in the Thai Buddhist Era, which is 543 years ahead of the Gregorian calendar — so 2026 is B.E. 2569. The holiday calendar combines Buddhist festivals, royal anniversaries and Songkran, the Thai New Year water festival in mid-April.

When a public holiday falls on a weekend, a substitute day is usually given on the following weekday. Buddhist holidays (Makha Bucha, Visakha Bucha, Asarnha Bucha, Khao Phansa) follow the lunar calendar and are confirmed by the Cabinet each year, so for 2027 only fixed-date holidays are shown.
