Thailand's public-holiday calendar can change how a trip feels. Hotels may be busier, family destinations fill up and some offices close even when shops stay open. A PersonalThailand post from 2008 listed that year's holidays; those dates are not safe for planning today. This updated guide explains what the official 2026 calendar says and how visitors should use it.
Quick takeaway: Use the Bank of Thailand calendar for financial-institution closures, check the specific government office separately and never reuse lunar-festival dates from another year.
Start with the correct holiday calendar
The Bank of Thailand (BOT) publishes an official list of holidays for financial institutions and specialized financial institutions. Its 2026 calendar includes New Year's Day on 1 January, Chakri Memorial Day on 6 April, Songkran on 13–15 April and Constitution Day on 10 December. The list is a strong reference for banking arrangements, not a universal guarantee that every office, shop or service follows the same schedule.
That distinction matters in practice. An immigration office, provincial government counter, hospital, museum and private shopping mall may all operate differently. Before travelling for an appointment, consult the service provider's own published hours and any recent special announcements. For cash access, ATMs and mobile banking can still be available while a bank branch is closed.
Songkran and the busiest travel periods
The 2026 BOT schedule lists Songkran on Monday 13, Tuesday 14 and Wednesday 15 April. It is the traditional Thai New Year and is widely associated with family visits and public water celebrations. Travel on major routes may be busier than on an ordinary weekday, especially when people go home to see relatives.
Avoid assuming that a restaurant, bus service or attraction will shut for all three days; it varies. Book essential transport ahead where possible and protect passports and electronics if you plan to take part in water events. Local authorities may issue specific restrictions for a celebration area, so follow current venue guidance rather than advice recycled from an earlier Songkran.
Buddhist observances move in the calendar
Makha Bucha, Visakha Bucha and Asarnha Bucha follow the lunar calendar. In 2026, the BOT lists Makha Bucha on 3 March, a substitute holiday for Visakha Bucha on 1 June and Asarnha Bucha on 29 July. Their dates will not stay on the same Western weekdays in future years.
These occasions are important religious observances as well as dates affecting business and official activity. Visitors planning temple trips should dress respectfully, give worshippers room and look for local instructions about ceremonies and access. Never apply last year's legal or venue-specific restrictions automatically to a new date.
Royal commemorations and year-end dates
The 2026 banking calendar includes the King's Birthday on 28 July, Mother's Day on 12 August, King Bhumibol Adulyadej Memorial Day on 13 October, Chulalongkorn Memorial Day on 23 October, a substitute holiday on 7 December for 5 December, and New Year's Eve on 31 December.
An older article called 5 December simply 'the King's Birthday', reflecting a different reign and time. That shorthand is misleading in a contemporary calendar. The BOT names 5 December as the birthday commemoration of King Bhumibol Adulyadej, National Day and Father's Day, with the 2026 substitute banking holiday on 7 December.
Additional or regional closures
Special holidays can be declared for particular places or circumstances. For example, the BOT's updated calendar includes an additional bank holiday in Bangkok on Friday 16 October 2026. A separate Bank of Thailand announcement describes the Bangkok-only context, linked to the IMF–World Bank annual meetings.
The practical lesson is that a holiday spreadsheet downloaded months earlier may be incomplete. Verify a date again close to travel, especially if you need time-sensitive banking, document processing or an embassy appointment. Some institutions and provinces follow supplementary arrangements, making local checks essential.
Are restaurants and tourist attractions open?
Major shopping centres, markets and restaurants often trade on public holidays, but opening hours can differ and some smaller family businesses take time off. Popular attractions may be busy even when government counters are closed. Treat each venue's current hours as more reliable than a blanket internet claim about 'everything closing'.
If a museum, national park or transport provider is central to your plans, review its official website and booking conditions. Make a backup plan for meals and transfers. You can still enjoy a holiday weekend without scheduling the one task that requires a public office to be open.
A traveller’s seven-day planning checklist
About a week before the relevant date, check the government or banking calendar, verify your hotel cancellation terms and review bookings with transport operators. Keep some cash in case your preferred branch is closed and note customer-service contacts for services you may need.
If you will stay long-term, put immigration and administrative deadlines on a separate calendar with reminders well before the due date. This article helps with planning but does not establish how any particular legal deadline is calculated around a holiday; confirm those rules with the responsible authority.
