These are the 10 public holidays in Finland 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 251 working days shown above are the 365 calendar days of 2025, minus the 104 Saturdays and Sundays, minus the 10 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 5 of Finland's public holidays. At a standard eight-hour day, 251 working days works out to roughly 2,008 working hours across the year, before any annual leave is taken.
Finnish Työaikalaki (Working Time Act) of 2019 sets a 40-hour standard week with collective agreements typically reducing this to 37.5. The standard private-sector week is Monday to Friday with banks operating Monday to Friday. The Code of Judicial Procedure (oikeudenkäymiskaari) rolls procedural deadlines falling on a Saturday, Sunday, public holiday, Midsummer's Eve, Christmas Eve or May Day to the next working day, an unusually broad list including pre-holiday eves. Settlement of euro transactions follows TARGET2; domestic Finnish bank-to-bank clearing observes the Bank of Finland calendar matching the statutory list.
Finland recognises nine state-recognised holidays and three church holidays for a total of twelve recognised days under the Laki kirkollisista juhlapäivistä ja yleisistä juhlapäivistä 1973. The list combines Lutheran dates (Epiphany, Good Friday, Easter Sunday, Easter Monday, Ascension, Whit Sunday, All Saints' Day on the Saturday between 31 October and 6 November, Christmas Day, Boxing Day) with civic dates (New Year's Day, May Day on 1 May, Midsummer Day on the Saturday between 20 and 26 June, Independence Day on 6 December commemorating the 1917 declaration of independence from Russia). Several holidays are recognised both as state and church days.
This matters because the working-day total is not spread evenly. Some months in Finland 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 20.9 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 Finland 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 Finland (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.
