H.M. Queen Sirikit, the Queen Mother’s Birthday / Mother’s Day

Queen Sirikit’s Birthday, the Queen Mother’s Birthday, is celebrated every year on 12 August and is one of Thailand’s most important national public holidays. The day honours the birthday of Her Majesty Queen Sirikit, the Queen Mother, while also serving as Mother’s Day throughout Thailand.

The occasion is marked by religious ceremonies, family gatherings and public displays of respect, making it a meaningful time to experience Thai culture during a visit to Chiang Mai.

Throughout Chiang Mai, streets, government buildings and public spaces are decorated with Thai national flags, light blue flags and portraits of the Queen Mother. Light blue is the colour traditionally associated with Queen Sirikit’s birthday, and many Thai people wear blue clothing as a sign of respect. Floral displays, decorative lighting and royal tributes can also be seen across the city.

The day often begins with merit-making ceremonies at Chiang Mai’s historic temples. Local families visit temples such as Wat Phra Singh, Wat Chedi Luang, Wat Phra That Doi Suthep and Wat Suan Dok to offer food to monks, make donations and pray for the Queen Mother’s health and wellbeing.

As a special occasion for families to spend time together and express gratitude to their mothers, Mother’s Day is also a time to present jasmine flowers, the traditional symbol of Mother’s Day in Thailand.

Visitors can enjoy Chiang Mai’s unique blend of culture and history throughout the holiday. Most tourist attractions remain open, allowing travellers to explore the Old City, browse boutique shops, visit local markets or enjoy the city’s renowned cafés and restaurants. While the holiday has a respectful and patriotic atmosphere, it is also warm and family-oriented.

During the evening, candle-lighting ceremonies and community gatherings may be held in honour of the Queen Mother. These events offer visitors an opportunity to witness an important national tradition and better understand the respect held for the Thai Royal Family.

August falls during Chiang Mai’s rainy season, so brief afternoon showers are possible. However, they rarely prevent visitors from enjoying the city’s many attractions.

Whether you spend the day exploring ancient temples, discovering local cuisine, or observing cultural traditions, Queen Sirikit’s Birthday and Mother’s Day provide a memorable opportunity to experience one of Thailand’s most significant public holidays.
