Academic term
In most countries, the academic year begins in late summer or early autumn and ends during the following spring or summer. In Northern Hemisphere countries, this means that the academic year lasts from August, September, or October to May, June, or July. In Southern Hemisphere countries, the academic year aligns with the calendar year, lasting from February or March to November or December. The summer may or may not be part of the term system.
Summer vacation
In the Netherlands, summer vacation is about 6 weeks for primary school and High school, usually from mid-July to late August. School students officially get the same time off but there often is a one-week period before the vacation during which the student will only have to go to school for 2 days to receive their grade lists and bring back their books making the holiday 7 weeks unofficially for high school students. However, this does not apply to every school.
