The number of weeks in a school year might vary significantly because each individual school district that a public school is a part of sets its own calendar. The private school in question determines how many weeks make up the academic year.
When everything is taken into account, a standard school timetable in the United States has an average of 180 school days spread out across 40 weeks of the year. This percentage also applies to some year-round schools, which give their pupils lengthier breaks throughout the regular September to June school year but a shorter summer break. As a result, year-round school students do attend summer sessions.
