The National Mother’s Day falls on August 12, which is generally observed as Her Majesty Queen Sirikit’s Birthday. Previously, April 15 was regarded as National Mother’s Day according to the consensus of the Cabinet’s directive issued on February 23, 1950. Consequently, the first celebration of Mother’s Day was observed on April 15, 1950, by the Office of the National Culture Commission. This celebration, which was a great success, included religious rituals, selection of ‘Devoted Mother’s and motto competitions, etc. In order to pay homage to ‘Mothers’ and to make Mother’s Day important, Field Marshal P. Phibulsongkram declared Mother’s Day as ‘National Mother’s Day.’
