When is King’s Birthday?
In 2026, King’s Birthday falls on Tuesday, July 28, 2026. It is classified here as a Thai public holiday.
History of King’s Birthday
King Maha Vajiralongkorn’s Birthday in Thailand is observed on July 28, his birth date in 1952. He became king after King Bhumibol’s death in 2016 and was crowned in 2019 as Rama X. The birthday is therefore distinct from May 4 Coronation Day and December 5, the late King Bhumibol’s birthday, National Day and Father’s Day. Keeping these identities separate prevents the royal calendar from becoming a set of interchangeable commemorations.
Formal activity may include government ceremonies, well-wishing books, merit-making, public decoration and volunteer projects. Yellow is associated with Monday, the King’s weekday of birth, and can appear in flags or clothing. Ceremonial language is official convention; historical description should neither endorse nor contest political claims about the monarchy and should acknowledge that personal participation varies.
Tuesday, July 28 is a government and Bank of Thailand holiday in 2026. It creates a three-day sequence for government offices with Asarnha Bucha on July 29 and Khao Phansa on July 30, but banks do not list Khao Phansa. Private employers select their own section 29 dates. Transport, tourism and emergency services plan separately for the connected period.
How King’s Birthday is observed
