Frequently asked questions
How do you correctly calculate a 30 working day period in Belgium to meet a legal deadline?
You must exclude Saturdays, Sundays, and the 10 Belgian public holidays. For example, a 30 working day period starting on January 2, 2026 will extend until February 17, 2026, accounting for New Year's Day and Easter Monday. A calculation tool or an updated calendar of Belgian public holidays ensures legal compliance.
Are 60-day payment deadlines affected by Belgian public holidays?
Yes, in the context of invoice payment deadlines, public holidays may affect the calculation of the final deadline. Although legally payment deadlines are calculated in calendar days and not working days, an invoice issued on May 15, 2026 (Ascension Day) could complicate administrative management. It is recommended to clearly communicate invoice dates and agreed deadlines to avoid any ambiguity.
Which Belgian public holidays in 2026 have the greatest impact on project planning?
Easter Monday (April 6), Ascension Day (May 14), Whit Monday (May 25), and the Assumption period (August 15) cause the most frequent interruptions. The National Holiday on July 21 can also affect teams on vacation. Planning major milestones while avoiding these periods optimizes project continuity.
How do you apply the 30 working day rule from the European Public Procurement Directive in Belgium?
The 30 working day rule for publication and appeal deadlines in public procurement must exclude Saturdays, Sundays, and the 10 Belgian public holidays. In 2026, this means that a publication on January 2 will see its deadline extended until at least February 12. Belgian public authorities must systematically use an updated calendar to comply with this European requirement.
Is there a difference between public holidays in Flanders, Wallonia, and Brussels for calculating deadlines?
No, the 10 Belgian public holidays listed apply uniformly throughout the country, whether you are in Flanders, Wallonia, or Brussels. Some regions may have additional days off according to sectoral collective agreements, but for legal calculations of administrative and commercial deadlines, these 10 national public holidays are the mandatory reference.
