The 260 working days shown above are the 366 calendar days of 2028, minus the 106 Saturdays and Sundays, minus the 0 public holidays that land on a weekday. Holidays that fall on a Saturday or Sunday are not subtracted, because they do not remove a day anyone would have worked; in 2028 that applies to 0 of Thailand's public holidays. At a standard eight-hour day, 260 working days works out to roughly 2,080 working hours across the year, before any annual leave is taken.
The Labour Protection Act section 23 sets the standard working week at 48 hours over six days, with the office and banking sector typically working 40 hours Monday to Friday. Sunday is the statutory weekly rest day under section 28. The Civil Procedure Code section 23 rolls procedural deadlines falling on a public holiday or weekly rest day to the next working day. Settlement of baht transactions runs on the Bank of Thailand's BAHTNET RTGS system and the National ITMX clearing for retail, which observe the thirteen statutory holidays plus Cabinet-declared bridge days where the bridge falls on a banking day.
Thailand recognises thirteen statutory public holidays under section 29 of the Labour Protection Act BE 2541 (1998), with the Cabinet adding annual substitution and bridge days by resolution. The list combines Buddhist dates (Makha Bucha, Visakha Bucha for the Buddha's birth-enlightenment-passing, Asahna Bucha and Khao Phansa marking the start of Buddhist Lent) with civic dates (New Year's Day, Chakri Memorial Day on 6 April, Songkran on 13 to 15 April for the Thai New Year water festival, Labour Day, Coronation Day, King Vajiralongkorn's birthday on 28 July, Mother's Day on 12 August, Passing of King Bhumibol, Chulalongkorn Day on 23 October, King Bhumibol's birthday, Constitution Day on 10 December, and New Year's Eve).
This matters because the working-day total is not spread evenly. Some months in Thailand carry several public holidays while others have none, so the month-by-month table above is the figure to use for payroll runs, billing cycles, SLA windows, and project plans rather than a flat assumption of about 21.7 working days per month. A month with two weekday holidays can have several fewer working days than a clear one, which changes capacity planning and the realistic delivery date for anything scheduled in business days.
To see the individual dates, the day of the week each holiday lands on, and the full official list, open the Thailand holiday calendar for 2028. You can subscribe to those dates as an .ics feed so they appear in your own calendar, or use the working-days-between-two-dates calculator to count business days for a specific date range rather than the whole year.
Working-day figures are computed from the public holiday list for Thailand (source: Nager.Date and the national references above) combined with a Monday-to-Friday business week. Regional holidays and substitute-day rules vary; confirm against the official calendar for legal or payroll use.
