King's birthday - Dec 5
Public holiday. This is the birthday of Bhumibol Adulyadej the Great, "the beloved King and father of all Thai people", and it is also Father's Day (like the Queen's birthday is also Mother's Day). All Thailand is dressed in yellow on this special day, as the King was born on a Monday, the day of the week to which yellow is associated. Thai people often wears a yellow shirt on Mondays, throughout the year, or on every occasion where they want to show their love and respect of the King.
