School days calculator
Count school days between two dates. Estimate weekdays in a term, semester, or school year and subtract break days manually.
How the school days calculator works
Enter a start date, an end date and the number of break or holiday days to subtract. The calculator counts every Monday to Friday from the start date to the end date, including both ends when they fall on a weekday. It then subtracts the break days you entered and shows the number of school days left.
It does not know your school’s calendar, so it does not remove holidays by itself. Enter your own number of weekday holidays, in-service days and breaks in the third box.
Worked example
| Step | Value |
|---|---|
| Start date | Monday, January 11, 2027 |
| End date | Friday, June 11, 2027 |
| Weekdays in range (both dates included) | 110 |
| Break days entered | 10 |
| School days | 100 |
If your range has fewer weekday holidays, enter fewer break days. A year of typical school calendars has between about 170 and 190 days, though it varies by country and region.
Handy for
- Students and parents counting down to the end of term.
- Teachers planning how many lessons fit before an exam.
- Homeschooling families checking they will meet a required number of days.
For all working days in a range, including weekdays only, use the business days calculator. For a countdown to a single date, use the semester countdown.
To see the last day of term at a glance, use the Left countdown widget on your Home Screen.
