School holiday
In places like America, summer vacation usually lasts from June until September (14 weeks) while in other places like England, summer vacation (or known as summer holidays over there) last for about 6 weeks from late July until the begining of September because they have a 2 week holiday for Christmas and a 2 week holiday for Easter and several 1 week holidays. In places like Australia, because they're in the Southern Hemisphere, they have their holidays for about 6 weeks like England but have their holidays from about mid December to late January because they have the two two week holidays like England and an extra two week holiday in October without having the extra one week holidays.
