This national holiday in Thailand is held annually on 5 December.

If 5 December falls on a weekend, the holiday will be observed on the following Monday.

The day commemorates the birthday of the late King of Thailand, Bhumibol Adulyadej. It is also Thailand's National Day and is the day when Father's Day is celebrated in Thailand.

History of King Bhumibol's Birthday

Known as Rama IX, he reigned Thailand since 9 June 1946 until his death on 13 October 2016, making him the longest-reigning monarch ever in Thailand's history.

His birthday will remain a national holiday in 2016 and likely beyond that.

Despite being a constitutional monarch, and not legally being allowed a role in politics, Bhumibol made several decisive interventions in the Thai political sphere and has been credited with helping facilitate Thailand's transition to democracy in the 1990s.

The holiday itself is a colourful affair. Buildings across Thailand will display flags, bunting and portraits of the late King, while around the Grand Palace area of Bangkok, the streets are decorated with thousands of marigolds.

Marigolds are chosen for their colour, as yellow is the predominant colour of the celebrations; as the King was born on a Monday and in Thailand, yellow is the colour for Monday.

To mark his passing in 2016, this year’s celebrations will include the auspicious assembly of 999 monks.

In the evening, the streets around Ratchadamnoen and Sanam Luang are closed to traffic and many people come to watch celebratory fireworks displays.
