One date calculator, three ways to count

3 calculation modes

Days between, workdays, and countdown — one tool, three modes that answer "how many days are there between two dates" at a glance. Open the page and start; you can also install it to your phone's home screen.

What each mode solves

When you'll reach for it

Counting leave days, working backwards from a contract expiry, scheduling a project in working days, counting down to an anniversary — these are all "distance between two dates" problems. The date calculator gathers them into one tool, so you never have to count on your fingers or pull formulas in a spreadsheet again.

How to read the result

After it calculates, that large monospace number is the answer, and the unit beneath it (days / workdays / days left) tells you what it means. The colored line under the number changes with the mode: blue for days between, amber for workdays, green for an upcoming countdown, slate for one that has passed — so you can tell which result you're looking at instantly.
