Queen Sirikit's birthday, as is the king's, is a national holiday, and is also Mothers' Day in Thailand. She is particularly revered in the more remote and traditional parts of the country, where the monarchy is regarded as semi-divine. Her work in promoting tolerance and understanding for the Muslim minorities in the southernmost provinces of Pattani, Yala and Narathiwat have made her especially popular amongst local Muslims [reference?]. The queen has a strong bond with southern Thailand. She spends months in the Muslim-majority provinces every year. The queen is considered to be one of the more quiet diplomats.[5]
