When is Cambodian King's Birthday?
This national holiday is celebrated from 13 May to 15 May each year.
The dates may vary if one or more of the three days fall on a weekend.
The holiday was established to celebrate the birthday of HM King Norodom Sihamoni.
HM King Norodom Sihamoni was born on 14 May 1953.
His Majesty King Norodom Sihamoni has been the sovereign of Cambodia since 29 October 2004.
He was made king after being chosen by a nine-member throne council to become the next king after his father Norodom Sihanouk abdicated in 2004 due to ill health.
Even though King Norodom Sihamoni's father was King, the King of Cambodia is an elected monarch, making Cambodia one of the few elected monarchies of the world.
The King is elected for life and is chosen by the Royal Council of the Throne. The only stipulations are that the candidates must be part of the royal family and at least 30 years old.
