Father's Day!
5 December is one of the most important days in Thailand.
It's Father's Day (วันพ่อแห่งชาติ "wan phâw hàeng châat").
The reason why we picked this day is because it's the birthday of His Majesty the King Bhumibol Adulyadej (Rama IX).
One phrase you will hear on Father's Day is ทรงพระเจริญ (Song phrá Jà-roen), which means "Long live the King".
On Father's Day, Thai schoolchildren invite their fathers to school and have a ceremony to wai (ไหว้ means "to pay respect") their fathers and offer flower garlands.
People will decorate their homes and shops with the Thai flags and display pictures of the King. And many people wear yellow because it the color of Monday, which is the day of the week that the King was born on.
In the evening, people will gather in a public space such as Sanam Luang in Bangkok to light candles to honor the King and say ทรงพระเจริญ 3 times. There will also be other events such as outdoor concerts and performances.
