Method: how Feestdagenwijzer calculates
Every tool runs on one engine in your browser. Below, for each part, the rule we follow, its source and how we test it. Data read on 13 November 2026.
The eleven official holidays
The list follows the government: New Year's Day, Good Friday, Easter Sunday and Monday, King's Day, Liberation Day, Ascension Day, Whit Sunday and Monday, Christmas Day and Boxing Day. King's Day is 27 April unless that is a Sunday, when it moves to Saturday 26 April (as in 2025 and 2031). A holiday at the weekend is not replaced by another day in the Netherlands.
Easter by Gauss, checked with Meeus
Easter is the first Sunday after the first full moon on or after 21 March. We compute it with Gauss's Easter formula and its Gregorian corrections. For 2027 the Easter limit, the ecclesiastical full moon, falls on March day 22; the next Sunday comes 6 days later, on March day 28, so Easter falls on 28 March 2027. A second method, Meeus's, must give the same date for every year from 1600 to 2600, or the test fails. Ascension follows 39 days after Easter, Whitsun 49 days, Good Friday 2 days before.
Who has the day off
No law gives employees a holiday off; the collective agreement (cao) or contract does (what a cao is). For each holiday we follow what the government writes on its Q&A pages: Easter Monday, King's Day, Ascension and Whit Monday are off at most companies and off for civil servants; on Good Friday you will probably work; on Liberation Day not everyone is off. By default we therefore count Good Friday and 5 May as working days; every tool lets you switch them on.
Bridge days and leave planning
A true bridge day is a single working day between a holiday off and the weekend, or between two days off. In 2027 those are 26 April 2027 and 7 May 2027. For a number of leave days, the planner finds the set of blocks giving the most consecutive days off (dynamic programming over every working block of one to ten days next to a day off); on a tie, the block with the best return per leave day wins.
Working days
Working days are Monday to Friday minus the holidays off under your choice. In 2027 the year has 261 weekdays and, by default, 256 working days.
School holidays by region
Dates come from the government overviews for 2026-2027, 2027-2028, 2028-2029 and 2029-2030, copied as published. Autumn and spring breaks are advisory: schools may deviate. The split of provinces and municipalities into North, Central and South follows the regional split, with the exceptions listed there per municipality.
Deadlines
The General Time Limits Act extends a statutory deadline ending on a Saturday, Sunday or generally recognised holiday to the next day that is none of these (section 1). Section 3 recognises New Year's Day, Easter Monday, Ascension Day, Whit Monday, both Christmas days, the day the King's birthday is celebrated and 5 May; Good Friday is treated the same by royal decree. Section 2 makes sure a deadline of at least three days contains at least two working days.
Licence and limits
The government publishes under CC0 1.0. This site does not know your agreement, your school's training days or a town's local holidays. We show no dates beyond the last published school year.
