King Maha Vajiralongkorn’s Birthday in Thailand Date in the current year: July 28, 2024

Vajiralongkorn’s father Bhumibol Adulyadej, also known as Rama IX and King Bhumibol the Great, ruled Thailand for 70 years. At the time of his death at the age of 88, he was the longest-reigning monarch in Thai history and the longest-serving head of state in the world. During the reign of Rama IX, the king’s birthday was celebrated on December 13.

King Bhumibol Adulyadej died of kidney failure on October 13, 2016. He was succeeded by his only son, crown prince Maha Vajiralongkorn. Vajiralongkorn was officially proclaimed the King of Thailand on December 1, 2016. He was expected to succeed to the throne immediately following his father’s death but asked for time to mourn. However, his reign was retroactively declared to have begun on December 13.

Vajiralongkorn’s personal life has been a controversial subject of discussion in Thailand, although not openly. There even were speculations that his younger sister, Princess Maha Chakri Sirindhorn, would succeed to the throne. Nevertheless, it was Maha Vajiralongkorn who became the King of Thailand and his birthday (July 28) was declared a national holiday.
