Bangkok, 5 December 2022 (TDI): The Royal Thai Government proclaimed December 5 as Thailand’s National Day. It is regarded as a special day in the Kingdom of Thailand. This commemorates the late King Bhumibol Adulyadej’s birthday anniversary.

The King was known as Rama IX, and he ruled Thailand from 9 June 1946 until his passing on October 13, 2016. This marked him the country’s longest-reigning king ever.

The current King of Thailand is Vajiralongkorn, often known as King Rama X, who took the throne in 2016 after the passing of his father. He proclaimed to celebrate the National Day of Thailand on the same day as his father’s birthday.


Previously, Thailand’s national holiday was observed on June 24 to celebrate the change from absolute monarchy to constitutional monarchy on June 24, 1932.

Furthermore, Field Marshal Sarit Thanarat was appointed Prime Minister on May 21, 1960, and another change was made on that day to honor the Thai King’s birthday.
