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 Estonia, summer holidays last for three months from June to August. Christmas holidays last for two weeks, autumn and spring holidays are each one week. In 2016, the Estonian Ministry of Education decided to add a new holiday, starting from 2017, to balance the learning weeks. There are going to be 5 holidays: Autumn holiday (21- 29 October), Winter Holiday (23 December- 7 January), a new holiday (24 February- 4 March), Spring holiday (21 April- 1 May) and Summer holiday (12 June- 31 August). Summer break starts 1 week later.
