Public holidays in Thailand are regulated by the government, and most are observed by both the public and private sectors. There are usually sixteen public holidays in a year, but more may be declared by the Cabinet. Note that the actual number of holidays for the individual is determined by the nature of the organization for which she works i.e. public, private, institutions governed by the Bank of Thailand or state-owned enterprises (excluding financial institutions). On average workers for the first three groups are entitled to fourteen holidays while state-owned enterprise workers enjoy up to fifteen holidays (or more). If a holiday falls on a weekend, one following workday is observed as a compensatory non-workday. The Bank of Thailand regulates bank holidays, which differ slightly from those observed by the government. Other observances, both official and non-official, local and international, are observed in varying degrees throughout the country.

Bank holidays 
Bank holidays (those observed by financial institutions, not to be confused with bank holidays in the United Kingdom) are regulated by the Bank of Thailand. These usually differ from government holidays in that banks do not observe the Royal Ploughing Ceremony day (Phuetchamongkhon) or the beginning of Vassa (Khao Phansa), but instead do observe 1 May as National Labour Day and 1 July as the mid-year bank holiday. (Prior to 2007, the beginning of Vassa was observed as a holiday rather than Asalha Puja.) Eid ul-Fitr is also designated as a holiday for financial institutions in Narathiwat, Pattani, Yala, and Satun Provinces if it does not already fall on a weekend or holiday.
