Thailand observes the birthday anniversary of Her Majesty Queen Sirikit, the Queen Mother, on 12 August each year, and also celebrates it nationally as Mother’s Day.
In 2027, the occasion falls on Thursday 12 August and remains an official public holiday.
Across Thailand, the day is marked with royal commemorations, Buddhist merit-making, National Mother’s Day activities and ceremonies organised by government agencies and local communities.
Queen Sirikit The Queen Mother
Queen Sirikit, the Queen Mother, was born on 12 August 1932 and has played an important role in modern Thai public life.
Her royal work has long been associated with rural development, environmental conservation, traditional Thai arts and crafts, and projects supporting communities throughout the country.
The SUPPORT Foundation, established under her patronage, has been particularly influential in preserving traditional handicrafts while creating employment opportunities for rural communities.
These contributions have helped make 12 August an important date on Thailand’s national calendar.
National Mother’s Day in Thailand
12 August is also Thailand’s National Mother’s Day.
The association reflects Queen Sirikit’s longstanding status as the Mother of the Thai Nation, and the day has become an opportunity for families across Thailand to recognise mothers and maternal figures.
Jasmine is traditionally associated with Mother’s Day and symbolises the purity and strength of maternal love.
Families may give jasmine garlands or flowers to their mothers, while schools and community organisations often hold Mother’s Day activities in the period leading up to the holiday.
Ceremonies in Chiang Mai
Chiang Mai traditionally marks 12 August with official and religious ceremonies.
Activities in previous years have included morning Buddhist merit-making, alms-giving to monks, ceremonies involving government officials and community organisations, and commemorative events at significant temples and public locations.
Wat Phra That Doi Suthep has also hosted important Buddhist ceremonies associated with the occasion.
The exact 2027 Chiang Mai ceremony locations, times and program have not yet been announced.
Buddhist Merit-Making
Buddhist ceremonies are an important part of the annual observance.
Morning activities may include monks chanting and receiving alms, with members of the public joining government officials and community representatives in making merit.
Temples around Chiang Mai may also organise prayers and other religious activities.
Visitors are generally welcome to observe public ceremonies, but should treat them as formal religious and national occasions rather than tourist performances.
