10 Major Thailand Public Holidays Introductions

Thai holidays follow their weekend holiday pattern. If statutory holiday days fall adjacent to a weekend, then that weekend becomes part of the holiday. If statutory holiday days fall on a weekend, then a Monday is added to the holiday. If statutory holiday days fall midweek, then they stand alone.

1. New Year's Day Holiday (30 Dec. – 2 Jan., 2025)

International New Year's Day (1 January) is the first of three New Year's Days celebrated in Thailand. This 4-day public holiday is from 30th December to 2nd January in 2025, as the statutory holidays of 1 Jan. and 2 Jan. are combined with the adjacent weekend, unless they fall midweek.

Events are held nationwide with fireworks displays and New Year countdown events taking place in most towns and cities in Thailand. Even though it is not the Buddhist New Year, many Thais visit local temples to offer alms to monks. Learn more about Where to Celebrate New Year's Eve in Thailand.

2. Makha Bucha Day (24 February, 2025)

Makha Bucha Day 2025 was on Saturday, February 24th. Thai people have one day off for this Buddhist public holiday. Makha Bucha Day celebrates some of the teachings that the Buddha delivered on this day many centuries ago.

However, in Thailand, the day is not celebrated the way it once used to be, with many just treating it as another day off.

5. Visakha Bucha Holiday (22 May, 2025)

Another important public holiday in Thailand is Visakha Bucha Day. Visakha Bucha Day (22 May, 2025) commemorates the birth, enlightenment, and death of the Buddha, which varies according to Thailand's lunar calendar, but is almost always in May. The holiday is 3 days with the adjacent weekend unless Visakha Bucha falls from Tuesday to Thursday.

Every year, 5 December is a public holiday for Thai people to pay respect to and honor the late King Bhumibol, whose birthday falls on that day. Thai people will have 1 day off from December 5.

10. Constitution Day (10 Dec., 2025)

There is only one day off in 2025 to celebrate Thailand's Constitution Day (10th December), as it falls on a Tuesday in 2025. It is a holiday for taking pride in the Thai monarchy as well as its constitution.

In the early 1930s, the country was going through an economic depression. King Rama VII struggled to carry the country through these troubled times and thus relinquished some of the monarchy's power by transforming the country's governance into a constitutional monarchy.

Tourism During Thailand Public Holidays

If you are planning a visit to Thailand during one of the public holidays, be advised that tourist attractions and hotels are quite crowded during these times. You should also account for the fact that banks and government buildings usually remain closed.

However, many businesses remain open on public holidays. So you will still be able to enjoy trips to the mall, restaurants, and popular tourist attractions.

For the reasons above, make sure you book flights, accommodation, and any visits to attractions in advance. We also suggest that you arrive as early as possible for all travel arrangements.
