Public holidays in Thailand
Public holidays in Thailand are regulated by the government, and most are observed by both the public and private sectors. There are usually nineteen public holidays in a year, but more may be declared by the cabinet. Other observances, both official and non-official, local and international, are observed to varying degrees throughout the country.
All public holidays are observed by government agencies, while the Bank of Thailand regulates bank holidays, which differ slightly from those observed by the government. Private businesses are required by the Labour Protection Act to observe at least 13 holidays per year, including National Labour Day, but may choose the other observances they follow. If a holiday falls on a weekend, one following workday is observed by the government as a compensatory holiday.

Up until 2018, a mid-year bank holiday was also observed on 1 July. Chinese New Year, Eid ul-Fitr and Eid al-Adha are also designated as holidays for financial institutions in Narathiwat, Pattani, Yala and Satun Provinces if they do not already fall on a weekend or holiday.National observances
