The Passing of King Bhumibol is a national holiday in Thailand that is observed annually on October 13th to commemorate the death of the late King Bhumibol Adulyadej in 2016. King Bhumibol was Thailand’s longest-reigning monarch and was credited with helping facilitate Thailand’s transition to democracy in the 1990s. On this day, a moment of silence is held across the nation at 3:52 pm to mark the exact time of his passing. The cultural significance of this holiday lies in the deep respect and reverence that the Thai people hold for their beloved king.
