Thailand National Day

Thailand National Day celebrates anually On December 5. The Thai celebrate the birth anniversary of King Bhumibol Adulyadej, also known as Rama IX. His birthday is also observed as National Day and National Father’s Day. Interestingly, when the incumbent king ascended the throne, his birthday (July 28) was declared as a public holiday, but wasn’t made National Day out of respect for everything that Bhumibol Adulyadej has done for the country.
