These dates are corroborated against the Bank of Thailand’s published financial-institutions holiday list, which aligns with Thailand’s nationwide public holidays. Last reviewed 2026-07-24. Lunar-calendar holy days (Makha Bucha, Visakha Bucha, Asarnha Bucha) change each year, and the government can announce additional special or substitution holidays. We do not publish a date we cannot verify — anything still pending official confirmation is clearly marked. Always confirm critical appointments (immigration, banks, land offices, schools) directly with the relevant office before a holiday.
BAANLYY presents this calendar as a factual public reference and is not a government authority. Public-holiday observance can vary between government offices, banks and private employers; some businesses extend closures around Songkran and New Year. This page updates as official 2026 announcements are confirmed.
