When is Khao Phansa?
In 2026, Khao Phansa falls on Thursday, July 30, 2026. It is classified here as a Thai public holiday.
History of Khao Phansa
Buddhist Lent Day in Thailand is Khao Phansa, the first waning-moon day after Asarnha Bucha and the beginning of the approximately three-month Vassa rains retreat. Monks traditionally remain based at one monastery except for permitted journeys, creating a sustained period for study and practice. The English expression ‘Buddhist Lent’ is conventional but should not imply that the observance duplicates Christian Lent.
Communities offer candles, robes, food and practical supplies for the retreat. Large wax-candle processions are especially associated with places such as Ubon Ratchathani, while other provinces have distinct local events. Laypeople may undertake personal commitments such as avoiding alcohol, keeping precepts or attending temple more regularly; these are voluntary disciplines rather than uniform legal requirements.
Thursday, July 30 is a government-office holiday in 2026 under Thailand’s civil-service calendar. It is absent from the Bank of Thailand’s nationwide 2026 financial-institution list, which closes for Asarnha Bucha on July 29 but not Khao Phansa. Private employers decide whether to select it among their statutory traditional holidays. This sector distinction is why the guide no longer calls closure uniformly nationwide.
