The History of Queen Mother's Birthday?

Queen Sirikit Kitiyakara was born on August 12, 1932, in Bangkok, Thailand. She is the wife of King Bhumibol Adulyadej (Rama IX), and mother of King Vajiralongkorn (Rama X). After her husband's passing in 2016, she became officially known as the Queen Mother of Thailand.

Before 1976, Mother's Day in Thailand was observed on April 15, but it was not linked to any royal figure or major national event.

In 1976, the Thai government officially declared August 12 as a national public holiday in honor of Queen Sirikit's birthday.

At the same time, Mother's Day was moved to August 12 to align with her birthday, recognizing her as the symbolic "Mother of the Nation".
