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.
School holiday
In Denmark the summer holiday lasts 6–7 weeks. Most schools also have one week of winter holiday and one week of autumn holiday, usually in February and October respectively. Finally, the schools are closed from just before Christmas until just after New Year.
