The Netherlands has the fewest national holidays in Europe, with just two official days (Queen's Day and Liberation Day) in addition to standard Christian festivals. Holidays are not pushed forward if they happen to fall on a Saturday or Sunday, but private companies sometimes compensate employees by giving them a day off on the previous Friday or following Monday. Unusually, there are two days commemorating war. Remembrance Day commemorates Dutch citizens who have died in all wars or peacekeeping missions since the second world war. It is marked with a two-minute silence at 20:00 and many other events, but is a 'working' day. Liberation Day marks the end of the German occupation and although celebrated every year, is only a public holiday once every five years (the next one is in 2010). For all Dutch citizens, Koninginnedag (Queen’s Day) is the big one (see annual events) – a riotous orgy of orangeness to celebrate the monarch’s birthday. There are a few additional regional variations in areas where carnavale is celebrated in February and March. The system for school holidays is one of staggered start/finish times between three regions (North, Central and South) - one year the summer holiday begins at the end of June, the next year you have to hang on until the third week of July. The timetable for international schools is different again, taking into account pupils' national holidays such as Thanksgiving. Public holidays (nationale feestdagen) are set by the Ministry for General Affairs (www.minaz.nl).
