New Year's Eve

    New Year's Eve (Thai: วันสิ้นปี) is observed in Thailand on 31 December. It closes the Western calendar year and is part of the public holiday period around New Year's Day.1,2

    History

    Thailand's present year-end holiday period is linked to the adoption of 1 January as the Western New Year date in 1941. The Thai Government describes 31 December and 1 January as public holidays around the New Year festive season.1

    The coexistence of the Western New Year and Songkran is important for understanding Thailand’s calendar culture. One date organizes the international civil year, while the other preserves the traditional Thai New Year with its family, temple and water customs.1

    Customs

    The evening is associated with countdown events, public celebrations, concerts and fireworks. The Tourism Authority of Thailand and TAT Newsroom list large countdowns in Bangkok and regional events in different parts of the country.1,3 Local programmes vary by city, province and year.

    Public countdowns are only one part of the season. Many people also plan journeys around the holiday period, so transport, hotels and tourist areas can be busier than on an ordinary weekend. At the same time, local celebrations can be very different: a large Bangkok countdown is not the same experience as a provincial temple visit or family gathering.1,3

    Good to know

    The holiday period is useful for distinguishing fixed public holidays from one-off special holidays. For example, the Bank of Thailand may list additional special days for financial institutions in a specific year, but those days should not automatically be treated as permanent annual holidays.2

    Legal status

    New Year's Eve is listed in Thailand's holiday calendars. The Bank of Thailand calendar includes 31 December 2026 as New Year's Eve for financial institutions.2
