In Belgium, there are ten official public holidays.
[1] However, some employers do award a day's holiday in accordance with union.
In addition to the above, the same legal text names all Sundays as public holidays (which is why Easter and Pentecost, which always fall on Sundays, are "feasted" by extending the Sunday holiday to the following Monday).
The days of the three communities are holidays for their civil servants and for employees of institutions controlled, supervised or financed by them (e.g. municipalities, universities) and may also be observed by banks in the community concerned.
King's Feast is a holiday observed by all (i.e. federal, community or regional, provincial and local) administrations, including some of the schools they organize.
