About King Rama X’s Birthday
King Rama X’s Birthday is a national holiday in Thailand held every year on 28 July. It marks the birthday of His Majesty King Maha Vajiralongkorn, the tenth monarch of the Chakri Dynasty, who was born on 28 July 1952. The day is observed across the country with religious ceremonies, merit-making, and public displays of loyalty to the throne, and it is recognised as an official public holiday on which government offices, banks, and schools close.
The Story Behind King Rama X’s Birthday
The Chakri Dynasty has reigned over Thailand since 1782, and the birthday of the reigning monarch has long held deep significance in Thai life. King Maha Vajiralongkorn Bodindradebayavarangkun, known formally as Rama X, was born in Bangkok on 28 July 1952, the only son of King Bhumibol Adulyadej (Rama IX) and Queen Sirikit. He was named Crown Prince in 1972 and spent decades as heir to the throne before his accession.
When King Bhumibol died in October 2016 after a reign of seventy years, the nation entered a long period of mourning. King Vajiralongkorn formally accepted the invitation to ascend the throne and was proclaimed king, with his reign dated from 13 October 2016. His elaborate coronation ceremonies took place in May 2019, following Thai royal custom that allows a respectful interval after the predecessor’s passing.
In 2017, the King’s Birthday on 28 July was confirmed as a national public holiday, replacing the previous arrangement tied to the late King Bhumibol’s birthday on 5 December (which is still observed as National Day and Father’s Day). The change reflected the transition of the monarchy from one reign to the next while keeping the tradition of honouring the sovereign’s birthday at the heart of the Thai calendar.
The colour yellow is closely associated with the King, because in Thai tradition each day of the week has its own colour and Monday, the day on which King Vajiralongkorn was born, is represented by yellow. In the weeks around the birthday, yellow flags, banners, and portraits appear on streets, public buildings, and homes throughout the kingdom.
