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.

The school year in Russia traditionally starts on September 1 ("The Knowledge Day"). The school year is divided into four terms (quarters), separated by one- or two-week holidays (the first week in November, the first two weeks in January, and the last week of March). The summer holiday lasts three months: June, July, and August. Generally the school year lasts until 25 May, which is also known as "The Last School-Bell" day celebrated by the graduates, their families and teachers. The school graduation ceremony - "Graduation Evening" () - is organized on June 20–25.
