An academic year typically lasts 160–180 days in the U.S., excluding weekends and holidays. To find out "how many days in a school year" or to calculate a specific date, use the Days from Today calculator.
There are normally mid-term or other breaks during the school year, along with festive holidays like Christmas and New Year in December and January, spring break in March or April, and a long summer break from late May or June to August or September. Typically, a school year in the U.S. lasts around 160–180 days. To find "how many days in a school year" or for precise planning, use a days calculator.
For those states where the winters are freezing and the snow, and for that matter ice, is not uncommon, the extra days are added to cover a possible Students Stay Home Day due to harsh weather conditions. Also, some districts set in-service days for teacher training, and occasional off days for teachers, and these are normally held two to three times in a year.
The number of school days by state is represented in the table below:

To calculate how many days in a school day, you may use “Day Counter” or “Days Between Dates” and input the starting date and the ending date of the school year to compute the exact result.
States often regulate school time by mandating a specific number of hours or minutes per school year. According to the Education Commission of the States, 39 states have such regulations. Some states offer flexibility, allowing districts to meet requirements either by the number of days or by total hours. For instance, Oklahoma permits either 180 days or 1,080 hours over 165 days.
In most of these states (26 out of 39), the annual time requirements vary by grade level. For example, South Dakota requires 875 hours per year for fourth graders but 962.5 hours for eighth graders. On average, fourth graders across these states need 997.8 hours per year, while 11th graders need between 720 hours (including lunch time) in Arizona to 1,260 minutes in Texas. The average requirement for 11th graders is 1,034.8 hours per year.
Alternatively, 29 states and D.C. set daily time requirements. In 16 of these, the requirements differ by grade level. For example, Pennsylvania mandates 2.5 hours for kindergarten, 5 hours for grades 1-8, and 5.5 hours for grades 9-12. Eighth graders' school days can range from 3 hours in Maryland and Missouri to 6.5 hours in Tennessee. New Hampshire and Oregon even set maximums for school day lengths - 6 hours in New Hampshire and 8 hours in Oregon.
Texas uniquely requires a minimum of 75,600 minutes (equivalent to 1,260 hours) per school year, including all breaks. Although previously, Texas mandated 7 hours per school day, including breaks, this would amount to a 180-day school year if followed.
To calculate how many weeks are in a school year, you can divide the number of school days by 7. For example:
This method provides a straightforward way to estimate the length of the school year in weeks, helping students, parents, and educators plan their schedules accordingly.
To convert the number of weeks in a school year to months, you can use the average number of weeks in a month. Typically, each month contains about 4.35 weeks. Using this figure, you can calculate the number of months in a school year:
Calculation: 40 weeks ÷ 4.35 weeks per month = approximately 9.2 months
Thus, the average school year in the United States is roughly 9.2 months long. This period covers the majority of the calendar year, providing a substantial time frame for educational activities while allowing for breaks and holidays.
Which state has the shortest school day?
Maryland and Missouri have the shortest school day for eighth graders, at 3 hours.
Which state has the longest school day?
Tennessee has the longest school day for eighth graders, at 6.5 hours.

Most states set a minimum number of school days per year. Here are some examples:
In conclusion, the number of school days varies significantly depending on the state in the U.S. While each state sets its own requirements, the typical range is between 160 and 180 days per year. This variation reflects the diverse educational policies and priorities across the country.
