School Days Counter: How Many School Days Are Left

Enter the first and last day of your school year or term, tick the weekdays that count, and list your days off, one date or date range per line. Press Count school days. You get the total number of school days, how many are done, how many are left, the percent done and the number of today.

Free to use, no sign-up. Everything runs in your browser: nothing you type is uploaded.

Weekdays that count

One per line. Write a single date like 2026-12-25, or a range like 2026-12-21 to 2027-01-01. Always year, month, day, with dashes.

Your dates are saved on this device only.

How to use it

  1. 1. Enter the term dates

    Choose the first and the last day of your school year or term. The tool starts with a September to June year, so change both dates to match yours.

  2. 2. Tick the weekdays that count

    Monday to Friday are ticked. Untick a day you do not teach, or tick Saturday if you do. The names follow the language of the page.

  3. 3. List your days off

    Write one date or one range per line, year first, for example 2026-12-21 to 2027-01-01. Holidays, trips and sick days all go here. Days outside the term are ignored.

  4. 4. Press Count school days

    You see the total, the days done up to today, the days left, the percent done and which school day today is. A line tells you if today is a day off or outside the term.

Ideas for class and home

  • Checking a required number of days

    Where a set number of school days is expected, enter your calendar and your breaks to see whether you reach it, and how many are left if you fall short.

  • Pacing a curriculum

    Divide the lessons in a book by the school days left to see how many lessons a day you need. Count again after a holiday or an unplanned week off.

  • Planning a term break

    Add a possible week away as a range of days off and press the button again. The school days left change at once, so you can compare plans before you book.

  • A countdown for the class

    Show the number of school days left on a class screen. Children enjoy watching the percent done grow, and it makes the end of the year feel close.

Questions and answers

Is the school days counter free?

Yes. It is free to use, with no sign-up, and you can count as many terms as you like.

Are my dates stored anywhere?

Only in this browser, on this device, so they are still here next time. Nothing is sent to a server, and clearing your browser data removes them.

How do I write days off?

Put one date or one range on each line, in the order year, month, day with dashes. A single date looks like 2026-12-25 and a range like 2026-12-21 to 2027-01-01.

Does it count today as a school day?

Yes, if today falls inside the term, on a weekday that counts and not on a day off. Today is then included in the days done and gives the school day number.
