These are the 4 public holidays in Vietnam that land on a weekday in 2025 and therefore remove a working day. Holidays that fall on a weekend are not listed here because they do not change the working-day total.
The 257 working days shown above are the 365 calendar days of 2025, minus the 104 Saturdays and Sundays, minus the 4 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 2025 that applies to 0 of Vietnam's public holidays. At a standard eight-hour day, 257 working days works out to roughly 2,056 working hours across the year, before any annual leave is taken.
Labour Code 2019 article 105 sets the standard working week at 48 hours over six days, with the State encouraging a 40-hour, five-day week. The standard office and banking week is Monday to Friday with Saturday and Sunday off; manufacturing and retail commonly run Monday to Saturday. Sunday is the statutory weekly rest day under article 111. The Civil Procedure Code article 152 rolls procedural deadlines falling on a non-working day to the next working day. Settlement of dong transactions runs on the State Bank of Vietnam's IBPS (Interbank Payment System), which observes the gazetted holiday list plus PM-extended Tết days.
Vietnam recognises eleven days of public holiday under article 112 of the Labour Code (Law 45/2019/QH14). The list is short by regional standards: New Year's Day, the Lunar New Year (Tết Nguyên Đán) cluster of five days centred on the first day of the first lunar month, Hung Kings Commemoration Day on the 10th day of the third lunar month honouring the legendary founders, Reunification Day on 30 April marking the 1975 fall of Saigon, Labour Day, National Day on 2 September commemorating the 1945 declaration of independence and an additional day adjacent to 2 September (added by 2021 amendment). Tết is by far the most economically significant holiday with nationwide migration to family villages.
This matters because the working-day total is not spread evenly. Some months in Vietnam 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 21.4 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 Vietnam holiday calendar for 2025. 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 Vietnam (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.
