Summer vacation can span anywhere from six to fourteen weeks, or 42 to 98 days, depending on the school district. According to the National Center for Education Statistics, the average instructional school year is 180.4 days long.
Summer break times vary depending on where the school is located in the United States. Summer vacation for most schools in the northern states begins in early June and ends in early September, whereas southern states dismiss students in late May and resume classes in late August. Almost many schools give students a partial week off in November to observe Thanksgiving, followed by a week or sometimes two weeks off in December to celebrate Christmas. Breaks in the fall and spring are also common.
