These are the 9 public holidays in Belgium that land on a weekday in 2027 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 252 working days shown above are the 365 calendar days of 2027, minus the 104 Saturdays and Sundays, minus the 9 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 2027 that applies to 5 of Belgium's public holidays. At a standard eight-hour day, 252 working days works out to roughly 2,016 working hours across the year, before any annual leave is taken.
Belgian labour law sets a 38-hour standard working week. The Code judiciaire article 53 rolls procedural deadlines falling on a Saturday, Sunday or a recognised public holiday to the next working day. The standard private-sector week is Monday to Friday with banks operating Monday to Friday. Settlement of euro transactions runs on TARGET2, with domestic Belgian banking using the National Bank of Belgium's calendar that mirrors the federal list of ten. Stock exchange holidays at Euronext Brussels follow the same federal list plus a few exchange-specific days such as 24 December afternoon and 31 December.
Belgium recognises ten federal public holidays under the Loi du 4 janvier 1974 sur les jours fériés. The list is shorter than its neighbours and mixes Catholic and civic dates: New Year's Day, Easter Monday, Labour Day, Ascension, Whit Monday, National Day on 21 July, Assumption, All Saints', Armistice Day on 11 November and Christmas Day. Each of the three regions and three communities adds its own community-level holiday: the Flemish community on 11 July, the French community on 27 September, the German-speaking community on 15 November. These community days are paid leave for public-sector employees of the relevant community only; private-sector observance is at the employer's discretion.
This matters because the working-day total is not spread evenly. Some months in Belgium 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 21.0 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 Belgium holiday calendar for 2027. 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 Belgium (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.
