When is Labour Day?
In 2026, Labour Day falls on Friday, May 1, 2026. It is classified here as a Thai public holiday.
History of Labour Day
National Labour Day in Thailand is observed on May 1 within the international workers’ movement. Thai labour organisations have used the date to raise questions of wages, occupational safety, social security, collective bargaining and migrant-worker protection. It is legally important because section 29 of the Labour Protection Act requires every covered employer to announce at least thirteen traditional holidays each year and expressly says that the list must include National Labour Day.
Worker federations and public agencies may hold marches, policy events, services or speeches, while many employees use the paid day for rest and family time. The experience is not uniform: transport, hotels, restaurants, entertainment, health care and continuous-process workplaces can require holiday work under applicable rules, with substitute leave or holiday pay arrangements. Informal and self-employed workers may not receive a paid break merely because the date appears on calendars.
Friday, May 1 is a Bank of Thailand financial-institution holiday in 2026, but ordinary government offices do not treat Labour Day as one of their annual civil-service holidays. Conversely, the private-sector entitlement is stronger here than for some government-only dates such as Royal Ploughing Ceremony Day. The guide therefore labels the sector distinction rather than calling every closure nationwide.
How Labour Day is observed

Unions and labour networks may organise speeches, marches or service activities addressing wages, safety, welfare and freedom of association.

Many formal employees spend the day with family, while essential, hospitality, transport and informal workers may continue working.
Dates and observance rules are checked against the official Thai official and legal guidance. Lunar-date and annual government, financial-sector or employer schedules should be confirmed against official notices.
