In Spain, Portugal, the Republic of Ireland, Italy, Greece, Georgia, Lithuania, Latvia, Lebanon, Romania and Russia, the summer break is normally three months, compared to two to six weeks (sometimes 3 months) in Australia, Brazil, the United Kingdom, Pakistan, Bangladesh, India, the Netherlands, Germany and Mexico.
Only some private schools run "Calendar B" in which there is a long vacation from mid or late-June to late-August or early-September.
About 4 percent of public schools in the U.S. use a balanced calendar that operates year-round with a shorter summer break.
[8] The modern school calendar has its roots in 19th-century school-reform movements seeking standardization between urban and rural areas.
This standardization was related to the emerging tax structures, laws around compulsory education, as well as a general sentiment that school should be an essential component of American childhood.
As train travel became more affordable, middle-class families followed similar patterns, keeping their children home during the hottest months of the year or going away for a summer vacation.
Many 19th- and early 20th-century Americans educators believed that too much learning in hot weather was bad for one's health and could result in heat exhaustion and injury, particularly for younger children, whose minds were still developing.
In many places, teachers would use the summer months for their own learning and professional development, including participating in seminars and courses like those held at Chautauqua.
While the origins of the summer holiday break are often believed to be rooted in agriculture and the idea children were needed to assist with planting and harvesting crops, this is inaccurate.
In India, summer vacation lasts for around 1.5 - 2 months (6-8 weeks), the minimum time and span of dates of which the Government decides for the most part while private schools are allowed to extend them.
[16][17] Some of the schools that complied are still in transition, their academic calendars still beginning in July, others in August, with their summer vacations adjusted accordingly.
For companies and public administrations, the most popular period is the end of July - beginning of August, coinciding with the construction holiday.
However, there is a tendency to keep shops, services and businesses open during the summer holidays, albeit with a more limited staffing.
For the summer vacation in particular, the start and end dates are coordinated among states and somewhat rotate, so the local school year varies in length.
This roster has been introduced in the 1970s to better distribute demand for hotel rooms and holiday homes throughout peak season.
This amounts to about half of the total school holidays, which also include up to two weeks each in autumn, winter (around Christmas) and spring (around Easter).
Primary schools in the Republic of Ireland are sixteen days longer, so they start their summer holiday at the end of June but do not return until the first week of September.
In Spain, the school year finishes in mid to late June and begins in early to mid-September.
However, the exact start and end dates can vary depending on the level of education and the type of school.
For the most accurate information on the academic year and vacation periods, it's best to consult the specific school or educational institution the student attends.
