Some countries only get six weeks or two months summer vacation because students supposedly forget large amounts of information learned in the past year (See: Summer learning loss).  Other education reformers believed that children were overstimulated in a system which required 48 weeks of schooling. They believe that over-schooling could lead to nervous disorders, depression, and insanity. 3]

Some critics of summer vacation point out that American students spend approximately 180 days (26 weeks) per year in school, but Asian students are “in school for 240 to 250 days”.

Summer holidays in Japan last from late July until early September. By country In Argentina, the school year ends by late November or early December and starts late February or even mid March (12 to 14 weeks).

The dates of Australian “school holidays” (the term used, rather than “vacation”) are determined by each state’s Department of Education, the Summer (also known as Christmas) holidays being the longest in duration. Typically Christmas or Summer holidays in Australia last approximately six weeks, usually from mid-December (depending on school year, see below) to late January. This is significantly shorter than the North American Summer vacation, but Australian schools also break for two weeks at Easter, and in June and September, giving students and teachers a total of twelve weeks of nnual holidays. In many public schools, years 10 through 12 will finish before December 15, allowing time to complete exam marking and results. Year 10 commonly finishes at the end of November, Year 11 at the end of October, and year 12 (Senior Year) also at mid or the end of October after 3 weeks of end-of-year exams. This can bring the normal 12 weeks of vacation to 20 weeks of vacation. The intervening periods of school operation without holidays are called “School Terms”, each term lasting approximately ten weeks.
All Australian states have relatively similar holiday periods between each term, but there is the ability for this to change around, such as for the Melbourne 2006 Commonwealth Games, when the first term in Victorian schools was shortened to 6 weeks and the other subsequently extended to 12 weeks due to severe disruptions to the public and private bus networks used by school students. Most private schools in Australia have up to four weeks of additional holidays, due to their longer teaching hours during term. In Austria, summer vacation varies by region.
