HM Queen Mother's Birthday & National Mother's Day

Celebrates the birthday of Queen Sirikit, the Queen Mother, and Thailand's National Mother's Day on August 12th

About this Holiday

August 12th is both the birthday of Her Majesty Queen Sirikit, the Queen Mother (born August 12, 1932), and Thailand's National Mother's Day — a combination reflecting her enduring status as the Mother of the Nation. Queen Sirikit, consort of King Bhumibol Adulyadej, is celebrated for her dedication to charitable work, preservation of Thai handicrafts, and support for rural communities. Thais celebrate the day by wearing blue (the Queen Mother's color), presenting flowers to their mothers, and participating in royal blessing ceremonies.
