How many weeks is the school year? Well, that depends on the schooling level, state, and the particular school you’re asking about.
At the high school level and below, there are usually 35 to 40 weeks in a school year, with 40 being the most common number. States normally require somewhere between 175 and 180 school days per year for public schools, with requirements sometimes varying for private and charter schools, as well as for homeschool students.
Because of holidays and cancellations, the 180-day requirement gets spread out over a much longer number of weeks.
First, we’ll take a look at college semesters, then we’ll go down to the K-12 level with a state-by-state rundown of when schools begin each year.
All right, let’s get down to business.
How Many Weeks is a College Semester?
Spring and fall college semesters range from 15 weeks to 17 weeks in length, while summer semesters may be much shorter, averaging around 12 weeks. These weeks also include time set aside for students to take exams.
Holidays can also impact the number of weeks at a school. For example, Christian colleges may give students the day off for Good Friday.
Other colleges divide the academic year into quarters, which are normally each 10 weeks long.
There are also trimesters, with 12-week terms that are held during the fall, winter, and spring. This arrangement is much less common. Trimesters can sometimes be as short as 10 weeks.
While many colleges have the same number of weeks off, those weeks off may be spaced throughout the year very differently, which leads us to the next sections.
How Long is Summer Break in College?
Summer break is by far the longest break in college, often lasting three months. This gives students the opportunities to land summer jobs and internships, or travel back home if their school is in a different state.
Summer break usually starts in May and ends in August, but the timing depends on the school. The middle of May and the end of August is probably the most common combo.
How Long is Thanksgiving Break in College?
Fall break often corresponds with Thanksgiving. Fall break is often shorter than other breaks and doesn’t last for a full week.
If a school’s fall break is on Thanksgiving week, it’s common to start the break on Wednesday so that students can travel home if desired.
How Long is Winter Break in College?
The transition from high school to college can be tough, but one good change is winter break. In college, winter break can last from 3 to 5 weeks.
That’s plenty of time to relax after some tough finals, enjoy family and friends, and maybe even pick up some work shifts.
How Long is Spring Break in College
While colleges offer longer winter breaks, that’s not the case with spring break. While there are always outliers, don’t expect more than a week of spring break.
On the bright side, spring break is usually longer than fall break at the college level. There aren’t many universities that cut spring break short of a week.
How Many Weeks is the School Year? (By State)
As states often leave it up to school districts (and winter storms) to decide when to hold classes, we’ll just share the number of days.
If states do mandate when schools should start or finish by, we’ll make sure to note it. This data is for all levels from kindergarten through 12th grade in high school.
The requirements often are only for public schools, so you’ll need to look up the specific private school to find information on their academic terms.
All right, let’s dive in!

Alaska schools also require 180 days of school, with 4-5 hours required depending on the grade level.
