About

School Days Calculator is a simple, fast tool that answers one question: how many school days are left? Set a start and end date, customize your weekends, holidays, teacher workdays, and vacations, and get an instant, accurate count.

The tool is built for the United States, where school calendars vary widely by district, state, and school type. Rather than pretend there is one universal calendar, we let you enter your own dates so the result matches your school.

Everything is calculated in your browser. There is no account, no server-side storage, and no personal data collection. Your settings can be saved locally on your device and shared through a link if you choose.
