Leave calendar Belgium 2027: which calendar is yours?

Each calendar only contains dates set in law, a collective agreement or a royal decree, or officially recommended by the regional social partners in construction. Choose one with this decision guide.

The public holidays in the 2027 leave calendar

These ten days apply to every employee in every sector. In 2027, 3 fall on a Saturday or Sunday.

A public holiday on a Saturday or Sunday is replaced by an ordinary working day, if that day is a normal day of inactivity in your company. Who picks that day depends on your sector: a joint committee decision comes first, then the works council, the union delegation or the employees. A sector had to notify the minister of its 2027 decision before 1 October 2026. How to fix the replacement days and what you pay is in replacement public holiday; the holidays themselves in Belgium public holidays 2027, and the days you can bridge in bridge days 2027.

The "All sectors" calendar contains the ten holidays without replacement days: you fix those yourself, unless your sector did. The construction calendars do contain the replacement days, because a royal decree sets them.

Construction leave calendar 2027: rest days and replacement days

In construction (JC 124) three kinds of days are fixed. They apply to every blue-collar worker, and you may not deviate from them.

KindRegime A (Flanders)Regime B (Wallonia)Basis
Spring rest days30 March 2027 and 31 March 20274 May 2027 and 5 May 2027agreement of 2 July 2026
November rest days2 November 2027 to 5 November 2027, and 12 November 2027same daysroyal decree of 4 October 2026
Rest day before Christmas24 December 2027same dayroyal decree of 4 October 2026
Year-end rest days28 December 2027 to 31 December 2027same daysagreement of 2 July 2026
Replacement for 1 May7 May 2027same dayroyal decree of 7 September 2026
Replacement for 15 August13 August 2027same dayroyal decree of 7 September 2026
Replacement for Christmas27 December 2027same dayroyal decree of 7 September 2026

Regime A applies to sites in the Flemish Region and the German-speaking Community, regime B in the Walloon Region. For a site in Brussels you choose. If you want the other regime, you conclude an agreement with the union delegation by 1 December 2026; without a delegation you decide yourself and post the decision before 15 December 2026. Notify Constructiv of your choice. On a rest day you pay no wages: Constructiv compensates the worker. Everything on rest days, exceptions and compensatory rest is in construction leave Belgium 2027 and in our guide to JC 124.

The construction holiday by province in the 2027 leave calendar

The summer holiday in construction is not in any collective agreement. Employer and employee organisations agree it per province as a recommendation. On 25 October 2026 these recommendations for 2027 were known:

RegionSummerDays off in AprilTo choose
East Flanders, excluding Lokeren12 July 2027 to 2 August 20271 April 2027 and 2 April 20273 days
City of Lokeren19 July 2027 to 9 August 20271 April 2027 and 2 April 20273 days
Province of Antwerp12 July 2027 to 30 July 2027none6 days
West Flanders19 July 2027 to 6 August 20271 April 2027 and 2 April 20274 days

Each arrangement adds up to the 20 statutory holiday days of a full-time worker in a five-day week; 21 July is a public holiday and does not count as a holiday day. In the province of Antwerp a subsidiary recommendation exists next to the main one, with a summer closure until 23 July 2027; in case of disagreement within a company the main recommendation applies. West Flanders gives three alternative proposals next to the recommendation.

A recommendation does not bind your company automatically. The holiday rules set the order: a joint committee decision, which the minister must receive by 31 December 2026 at the latest; otherwise the works council; otherwise an agreement with the union delegation or the employees; otherwise an arrangement per employee. An employee is entitled to 2 weeks of uninterrupted holiday between 1 May and 31 October, unless they ask otherwise. How many holiday days your staff have is in annual leave Belgium 2027.

Worked example: how many working days does the 2027 construction calendar have?

Worked example: a full-time construction worker in East Flanders

A schedule starts with the number of days the team is actually on site. For a worker in a five-day week, regime A, with the East Flanders construction holiday:

StepDays
Weekdays Monday to Friday in 2027261
Public holidays on a weekday- 7
Construction replacement days- 3
Regime A rest days- 12
Statutory holiday days: construction holiday, April and days to choose- 20
Days on site219

Sickness, short leave and bad weather still come off that. If you price a quote in man-days, start from this number and not from 52 weeks of five days. A worker who starts during the year has fewer holiday days: those are calculated on his 2026 work.

The rest days are also called ADV days; where they come from is in ADV days. What else the sector requires is on our page about the construction sector. A day off for a wedding or funeral falls under short leave for family events, not under holidays.

Adding the leave calendar to your agenda

Each calendar exists as an .ics file, the standard for calendars. The days appear as all-day events, with the type and the source in the description.

  1. Outlook. Open the file with a double click, or choose Add calendar and then Upload from file. Outlook creates a separate calendar that you can show or hide next to your own.
  2. Google Calendar. Go to Settings, Import and export, choose the file and the calendar the days should go into. Preferably create a separate "Leave calendar 2027" first, so you can delete it in one go later.
  3. Apple Calendar. Open the file on your Mac, iPhone or iPad and choose the calendar it should go into.

Share the file with your team leaders and accountant, or post the PDF in the canteen and with the work rules. We incorporate changes in an official source into the file; whoever downloads it again has the new version.

What you arrange with the 2027 leave calendar before 15 December

  1. Choose your calendar with the decision guide above.
  2. Fix the replacement days if your sector did not, and post the notice before 15 December 2026. Attach a copy to the work rules.
  3. In construction: decide on the regime before 1 December 2026 if you want to switch regime or are based in Brussels, and post the decision before 15 December 2026.
  4. Fix the collective holiday, following the recommendation or with your own dates, in the way the holiday rules require.
  5. Update the work rules. If you change them, employees have 15 days to comment. How that works is in work rules.
  6. Plan your staff's leave around the fixed days. If an employee asks for leave on a busy day, see what is allowed in can an employer refuse holiday.

Electricians (JSC 149.01) also have twelve compensatory rest days, unless the company applies an effective 38-hour week; their dates are set per company, so they are not in these calendars. Other types of leave, from short leave to career breaks, are in types of leave. What else changes for employers in 2027 is in what changes in 2027.
