Teachers' Day in Thailand is observed every January 16, commemorating the enactment of the Teachers Act, which was published in the Royal Thai Government Gazette on January 16, 1945. The first celebration took place in 1957, following a resolution by the Royal Thai Government in 1956. This day is typically a non-working day for teachers, with most schools in Thailand closing to allow educators a break, although international schools may remain open and hold celebrations in honor of their teaching staff. While official public commemorations are uncommon, the holiday is marked by a quiet appreciation of teachers. Additionally, Thai teachers are honored at the beginning of the school year during the wai khru ceremony, where students express their gratitude through Buddhist prayers, offerings, and speeches by headteachers.
