Different places (climate reasons) are different from schools (staggered holidays for traffic convenience), usually from late June to late July.
Colleges and universities basically start summer vacation in July, and the holiday ends from the end of August to the beginning of September. Most summer vacations last more than 30 days. Because there are many schools all over the country, the state has not stipulated the date and time of college students' winter and summer vacations. Generally, it is stipulated by our school, so the time is different. In the south, the summer vacation is longer, because the summer time is longer and the weather in the south is particularly hot.
