For employees, knowing the Thailand public holiday calendar for 2027 in advance can help you plan your annual leave strategically and make the most of your vacation days. For HR teams, it also makes it easier to prepare work schedules, manage workforce availability, and organize the company’s annual holiday calendar.

Having HR software or HR payroll software integrated with a Leave Management system can further reduce HR’s administrative workload while making it easier for employees and managers to check leave balances, holidays, and leave entitlements.

Note: The 2027 holiday information in this article is based on currently available calendars and information on important dates.

January 2027 Holidays

The year begins with a public holiday that falls right before the weekend. Employees who work Monday to Friday can enjoy a 3-day break from 1–3 January without using any annual leave.

February 2027 Holidays

• Sunday, 21 February 2027 — Makha Bucha Day
• Monday, 22 February 2027 — Substitution Holiday for Makha Bucha Day

February offers a 3-day long weekend from Saturday, 20 February to Monday, 22 February. It is an ideal opportunity for a short trip or a relaxing break without using any annual leave.

March 2027 Holidays

• No regular public holidays

For employees with unused or accumulated annual leave, March may be a good time to take a vacation, as there are no regular public holidays during the month.

April 2027 Holidays

• Tuesday, 6 April 2027 — Chakri Memorial Day
• Tuesday, 13 April – Thursday, 15 April 2027 — Songkran Festival

April is one of the best months for planning annual leave in Thailand in 2027.

Songkran, in particular, offers an excellent opportunity to create an extended holiday. By taking annual leave on Monday, 12 April and Friday, 16 April, employees can connect the weekends before and after Songkran to enjoy a 9-day break from 10–18 April, while using only 2 days of annual leave.

This makes it a great period for returning to your hometown, travelling domestically or internationally, or simply enjoying an extended break.

May 2027 Holidays

• Saturday, 1 May 2027 — National Labour Day
• Tuesday, 4 May 2027 — Coronation Day
• Thursday, 20 May 2027 — Visakha Bucha Day

June 2027 Holidays

• Thursday, 3 June 2027 — H.M. Queen Suthida Bajrasudhabimalalakshana’s Birthday

Employees looking for a longer break can take Friday, 4 June as annual leave and connect the public holiday with the weekend, creating a 4-day break from 3–6 June.

• Monday, 19 July 2027 — Buddhist Lent Day /Related Substitution Holiday Period
• Wednesday, 28 July 2027 — H.M. King Maha Vajiralongkorn Phra Vajiraklaochaoyuhua’s Birthday

As Asarnha Bucha Day and Buddhist Lent Day fall close together in 2027, employees and HR teams should check the official announcements regarding substitution holidays for their respective organizations before making leave or travel plans.

August 2027 Holidays

• Thursday, 12 August 2027 — H.M. Queen Sirikit The Queen Mother’s Birthday / Mother’s Day

Employees can take just one day of annual leave on Friday, 13 August to connect the public holiday with the weekend, creating a 4-day break from 12–15 August.

September 2027 Holidays

• Saturday, 23 October 2027 — Chulalongkorn Day

For employees planning a year-end trip, October is another month worth watching. Several important holidays fall during the month, and an additional substitution holiday may create an opportunity for a longer weekend.

November 2027 Holidays

• No regular public holidays

Although there are no regular public holidays in November, many employees may begin using their remaining annual leave as the year draws to a close. HR teams should therefore monitor workforce availability and coordinate leave schedules to ensure business continuity.

December offers several opportunities for long weekends in Thailand in 2027. Constitution Day falls on a Friday, giving employees who normally have Saturdays and Sundays off an automatic 3-day weekend.

New Year’s Eve also falls on a Friday, allowing employees to connect the holiday with the weekend and the New Year holiday period in 2028. This makes late December an ideal time for travelling or returning home for the festive season.

If you are planning a trip or simply want a longer break in 2027, checking the Thailand public holiday calendar for 2027 in advance can help you use your annual leave more strategically.

For employees who work Monday to Friday and normally have Saturdays and Sundays off, consider saving your annual leave for the following periods.

April 2027: Take 2 Days of Annual Leave for a 9-Day Songkran Break

Songkran 2027 falls from Tuesday, 13 April to Thursday, 15 April. If your company observes these dates as holidays, you can take just two additional days of annual leave:

• Monday, 12 April 2027
• Friday, 16 April 2027

Combined with the weekends before and after Songkran, this gives you a continuous break from Saturday, 10 April to Sunday, 18 April — a total of 9 days while using only 2 days of annual leave.

This is one of the most efficient ways to use your annual leave in 2027, particularly if you are planning to travel abroad, return to your hometown, or simply enjoy an extended break during Songkran.

June 2027: Take 1 Day of Annual Leave for a 4-Day Break

Thursday, 3 June 2027 is a public holiday for H.M. Queen Suthida Bajrasudhabimalalakshana’s Birthday.

By taking annual leave on Friday, 4 June 2027, you can connect the public holiday with Saturday and Sunday and enjoy 4 consecutive days off from 3–6 June, while using only one day of annual leave.

This is a convenient option for a 3–4 day getaway without using too much of your annual leave allowance.

August 2027: Take 1 Day of Annual Leave for a 4-Day Mother’s Day Break

Thursday, 12 August 2027 is H.M. Queen Sirikit The Queen Mother’s Birthday and Thailand’s Mother’s Day.

Take annual leave on Friday, 13 August 2027, and you can connect the holiday with the weekend to enjoy 4 consecutive days off from Thursday, 12 August to Sunday, 15 August, using only one day of annual leave.

October 2027: Use Annual Leave to Extend a Midweek Holiday

October has several important holidays, including Wednesday, 13 October 2027 — H.M. King Bhumibol Adulyadej The Great Memorial Day, while Chulalongkorn Day falls on Saturday, 23 October.

For the 13 October holiday, employees who want a longer break can take annual leave on Monday, 11 October and Tuesday, 12 October. This creates a 5-day break from 9–13 October while using 2 days of annual leave.

Alternatively, take Thursday, 14 October and Friday, 15 October to enjoy another 5-day break from 13–17 October, again using only 2 days of annual leave.

For the Chulalongkorn Day substitution holiday, check the official holiday announcement. If a substitution holiday is designated for Monday, employees may be able to enjoy a 3-day weekend without using annual leave.

December 2027: Save Annual Leave for a Year-End Holiday

December is another good month to save some annual leave, with several public holidays toward the end of the year.

Friday, 10 December 2027 is Constitution Day, giving employees who normally have weekends off a 3-day break from 10–12 December without using annual leave.

Meanwhile, Friday, 31 December 2027 is New Year’s Eve, followed by the New Year holiday period in 2028. Employees who save some annual leave for late December may be able to create an extended year-end break for travelling or returning home during the festive season.

Which Annual Leave Dates Offer the Best Value in 2027?

If you have a limited number of annual leave days and want to maximize your long weekends in Thailand in 2027, some of the most valuable dates to take off are 12 and 16 April, 4 June, and 13 August 2027.

The Songkran period is particularly attractive: using just 2 days of annual leave can potentially give you 9 consecutive days off.

However, it is always a good idea to plan and submit your leave requests early, especially during popular holiday periods when several employees on the same team may want to take leave at the same time.

Public holiday policies may also vary between private companies, and additional special or substitution holidays may be announced. Employees should therefore check their company’s annual holiday calendar and leave policy with HR before booking flights, accommodation, or making other travel arrangements.

For HR teams, managing the 2027 holiday calendar involves much more than simply announcing the company’s annual holidays. HR must also manage employee leave entitlements, approve leave requests, calculate working days, and ensure accurate information is passed to payroll for salary and holiday-pay calculations.

As an organization grows, relying on documents or spreadsheets to track employee leave can result in duplicated information, delayed approvals, and errors when transferring leave and attendance data to payroll.

A Leave Management system integrated with HR payroll software allows employees to check their leave entitlements and submit leave requests online. Managers can easily review workforce availability and approve requests, while HR can manage holidays, leave records, and payroll-related information through connected systems.

Good holiday planning gives employees the opportunity to rest and recharge while helping organizations maintain the right workforce coverage. This becomes particularly important during long holiday periods in 2027, when many employees may submit leave requests at the same time.

With Sprout One and its online leave management system, organizations can manage holidays and employee leave entitlements more systematically — from submitting and approving leave requests to checking remaining leave balances and connecting leave data with payroll.

This reduces paperwork and makes collaboration between employees, managers, and HR teams easier and more efficient.

If your organization is looking for HR software, an online leave management system, or HR payroll software to make workforce management in 2027 easier and more accurate, Sprout can help connect your HR processes — from employee leave management to payroll — all in one place.
