School days calculator
Count school days between two dates. Estimate weekdays in a term, semester, or school year and subtract break days manually.
How school days are counted
This calculator counts weekdays between the start and end dates, then lets you subtract breaks or public holidays manually. That gives a practical school-day estimate for terms, semesters, and school years.
Why holidays are manual
School calendars vary by country, state, district, and institution. A manual break-day field keeps the calculator flexible without pretending every calendar follows the same holidays.
Planning assignments and exams
When you know the actual number of school days left, deadlines feel clearer. Use the result to pace revision, projects, and reading plans.
