History of King Maha Vajiralongkorn's Birthday

Known as Rama X, King Vajiralongkorn has reigned Thailand since October 13th 2016, following the death of his father, King Bhumibol. His father had ruled Thailand for over 70 years and as a mark of respect and to allow the country to mourn the passing of their beloved king, Vajiralongkorn did not accept the throne until December 1st 2016.

Vajiralongkorn was born on July 28th 1952. He is the only son of King Bhumibol Adulyadej and Queen Sirikit.

Vajiralongkorn was 64 when he became king, making him the oldest Thai monarch to ascend to the throne.

Previously this holiday was celebrated on the birthday of King Bhumibol Adulyadej on December 5th. From 2017, the King's Birthday has shifted to July 28th, but December 5th remains a public holiday in Thailand to mark the birthday of King Bhumibol Adulyadej.

On H.M. King's Birthday, most government offices, banks and businesses will be closed. Many shops will remain open and there is no ban on the sale of alcohol.
