Which Thai public holidays shut down intercity transport and make point to point travel genuinely dangerous or impossible?

Songkran, April 13 to 15, is the only holiday that makes travel genuinely dangerous. Drunk driving fatalities spike, intercity buses sell out, and roads are chaotic with water fights. New Year's Eve and New Year's Day cause severe congestion but not the same safety risk.

How do I find the exact dates for lunar holidays like Makha Bucha or Visakha Bucha?

The Thai Cabinet announces the dates annually. Check the calendar on the Tourism Authority of Thailand website or the official Thai government gazette. The dates change every year because they follow the full moon of the third, sixth, and eighth lunar months.

Do banks close on lunar holidays?

Yes. Banks close on all national public holidays, including the five Buddhist lunar observances. ATMs remain operational but charge a 220 THB fee for foreign cards.

Is alcohol sales banned on Songkran?

No. Alcohol sales are not banned on Songkran. The ban applies only to the five Buddhist holy days: Makha Bucha, Visakha Bucha, Asahna Bucha, Khao Phansa, and Ok Phansa.

What happens if my visa expires on a public holiday?

You cannot extend your visa on a public holiday because immigration counters are closed. You overstay and pay 500 THB per day up to 20,000 THB. Extend your visa at least three working days before any holiday closure.

Do trains and buses run on Songkran?

They run, but they sell out. VIP buses and State Railway of Thailand sleeper trains are booked solid up to two weeks in advance. Low cost airlines raise fares. If you have not booked by late March, you will not get a seat.

Do I need to avoid all of April because of Songkran?

No. Travel before April 10 or after April 18. The week between April 12 and April 17 is the disruption window. Outside that, Thailand operates normally. The burning season in the north is a separate problem: PM2.5 levels in Chiang Mai are hazardous from February through April.

Thailand Public Holidays and What They Do to Travel

The Days Thailand Closes, the Ones That Move, and Why it Matters

Songkran turns Thailand into a nation of water fights and makes point to point travel genuinely dangerous. The three official days April 13 to 15 stretch into a full week of closed businesses, fully booked buses, and a spike in drunk driving fatalities. This is a logistical warning. You will not find a list of festivals to enjoy here. You will find the dates that shut down intercity transport, the lunar observances that shift every year, and the alcohol sales bans that catch first time Asia backpackers off guard. A Thailand public holidays calendar is not a curiosity. It is the difference between a smooth trip and being stranded in a bus terminal at midnight with no onward ticket.

Songkran Travel Disruption: What Actually Breaks

During Songkran, road fatalities triple. The authorities publish the daily death toll. You do not want to be part of it. Intercity VIP buses are booked solid up to a week in advance. Trains on the Northern Line from the capital to Chiang Mai sell out early. Low cost carriers like Thai AirAsia and Nok Air raise fares on remaining seats. Private businesses in the capital and Chiang Mai close for four to seven days. Banks and immigration counters close for the official three days and do not reopen until the substitute weekday if a date falls on a weekend.

Arrive during the Songkran window and you will not get a visa extension. Do not rent a car. The roads are too dangerous. You will struggle to book a bus out of town. The failure case: you sit in a guesthouse on Khao San Road watching water fights for five days while your itinerary collapses. Skip it. Travel before April 10 or after April 18.

Thai Lunar Holidays Dates: the Ones That Move Every Year

Four Buddhist Observances That Shift

Four Buddhist observances shift annually because they follow the full moon of the third, sixth, and eighth lunar months. Makha Bucha Day falls on the full moon of the third lunar month, usually late February or March. Visakha Bucha Day, the full moon of the sixth lunar month, lands in May. Asahna Bucha Day, the full moon of the eighth lunar month, arrives in July. Buddhist Lent Day, Khao Phansa, starts the day after Asahna Bucha and runs three months until Ok Phansa.

The Royal Ploughing Ceremony

The Royal Ploughing Ceremony does not follow the moon. Royal astrologers set the date and it usually falls in May. You cannot predict these dates more than a year out. Check the Thai Cabinet announcement or the calendar published by the Tourism Authority of Thailand for the exact dates of your travel year. If you need a visa extension, confirm that the immigration counter is open on the day you plan to visit. A lunar closure means you wait another day.

Loy Krathong Dates: When the Festival Actually Lands

Loy Krathong is not a national public holiday. It falls on the full moon of the twelfth lunar month, usually November. Banks and state offices stay open. No alcohol sales ban applies. The disruption is entirely about crowds and accommodation. In Chiang Mai, the old city fills with domestic tourists. Hotels in the moat area book out months ahead. In the capital, the parks and riverfront are packed. Loy Krathong does not shut down transport, but it spikes demand on the Northern Line trains and flights between the capital and Chiang Mai. Book your accommodation and onward ticket before you arrive. Wait until you land and you pay double or sleep far from the action.

Thailand Bank Holidays: Who Closes and What You Cannot Do

Banks close on all 16 national public holidays and on any substitution day declared when a holiday falls on a weekend. You cannot exchange currency at a bank counter on those days. ATMs still work, but the foreign card fee of 220 THB per withdrawal applies. State immigration counters close too. If your visa exemption stamp runs out on a bank holiday, you overstay. The fine is 500 THB per day up to 20,000 THB. Do not let your passport expiration or visa expiry date fall inside a holiday closure. Extend early.

Alcohol Bans on Holy Days

Alcohol sales are banned nationwide on five Buddhist holy days: Makha Bucha, Visakha Bucha, Asahna Bucha, Buddhist Lent Day, and End of Buddhist Lent. The ban covers retail outlets, bars, and entertainment venues. On Ko Pha Ngan during one of these dates, the Full Moon party does not happen. In the capital, you drink in your hotel room with what you bought the day before. The ban runs from midnight to midnight. Plan your supply.

Fixed Gregorian Holidays vs Lunar Holidays: What Shuts Down

Lunar Buddhist	Makha Bucha (Feb/Mar), Visakha Bucha (May), Asahna Bucha (Jul)	State offices, banks, immigration	Nationwide ban on all five dates	Minimal outside the holiday itself
Regional non holidays	Chinese New Year (Jan/Feb), Vegetarian Festival (Sep/Oct)	Some businesses in Thai Chinese areas	No national ban	Minimal, except Phuket during Vegetarian Festival

What Shuts on Songkran and New Year

Songkran Closures and Transport

The official Songkran dates are April 13, 14, and 15. The authorities declare substitution days if these fall on a weekend. In practice, many businesses shut from April 12 to April 17. Banks close. Immigration counters close. Tourist businesses in the capital, Chiang Mai, and Phuket stay open, but street food vendors and small shops in residential areas shut. Intercity buses from Bor Kor Sor terminals are booked out. State Railway of Thailand sleeper services on the Northern and Southern lines sell out two weeks ahead. Low cost airlines raise their base fare.

New Year Congestion

New Year's Eve and New Year's Day, December 31 and January 1, follow a similar pattern. State offices and banks close. Intercity transport is heavily congested with domestic travellers returning home. Need to move between the capital and Isaan over New Year? Book your bus or train ticket 30 days ahead. The booking window opens 30 days in advance for most SRT trains and 90 days for special services. Mark the date on your calendar and book the moment it opens.

What Shuts on Buddhist Holidays

On Makha Bucha, Visakha Bucha, Asahna Bucha, Khao Phansa, and Ok Phansa, the same rule applies. State offices and banks close. Immigration counters close. Alcohol sales are prohibited nationwide from midnight to midnight. Bars and entertainment venues shut their doors. Retail alcohol sales in 7 Eleven, supermarkets, and convenience stores stop. Running a visa trip as a digital uPhone? Check the date of the next Buddhist observance before you travel to a border crossing. A holiday means the immigration post at the border is closed. You wait a day or risk overstay.

The alcohol ban is enforced strictly in tourist areas. Patong, Khao San Road, and Walking Street in Chiang Mai go dry. The tourist police hotline is 1155. The practical move is simpler: buy your beer the day before and drink it in your room.

The Practical Effect on Visa Extensions and Government Errands

On a 30 day visa exemption or a 15 day visa on arrival, a public holiday can break your timeline. Immigration counters at Chaeng Wattana in the capital and on the superhighway in Chiang Mai close on all national holidays. They do not process extensions on substitution days either. Your visa expires on a Monday that is a substitution day? You cannot apply until Tuesday. The overstay clock ticks.

State offices also close for the Royal Ploughing Ceremony in May and for Coronation Day on May 4. Need a certificate of residence, a police clearance, or any document from a district office? Check the holiday calendar first. A missed day in the capital costs you a full day of sightseeing and the cost of a hotel night you did not plan for.

How to Avoid Arriving During a National Shutdown

Mark Every Fixed Date

Open a calendar and mark every 2026 date for the fixed holidays: January 1, April 6 for Chakri Memorial Day, April 13 to 15 for Songkran, May 1 for Labour Day, May 4 for Coronation Day, June 3 for the Queen's Birthday, July 28 for the King's Birthday, August 12 for Mother's Day, October 13 for King Bhumibol Memorial Day, October 23 for King Chulalongkorn Memorial Day, December 5 for Father's Day, December 10 for Constitution Day, and December 31 for New Year's Eve. Then mark the five lunar observances by checking the Thai Cabinet announcement for 2026. The lunar dates will be published by late 2025.

Book Transport Before the Crush

Book intercity transport before the holiday. The State Railway of Thailand opens bookings 30 days ahead for most trains and 90 days for special trains. The Transport Company Limited, Bor Kor Sor, opens bus bookings 30 to 60 days ahead. Low cost carrier websites show fares 60 days out. Travelling during Songkran or New Year? Book every leg before you leave your home country. The failure case is standing at Mo Chit bus terminal on April 12 with no ticket and a guesthouse in Chiang Mai that will not refund your deposit.
