Frequently asked questions

How do I count the days between two dates?

Pick the start date and the end date. The tool shows the total days between them, and also breaks it down into weeks, months and years.

What counts as a working day?

Working days are Monday to Friday, excluding Saturday and Sunday. Public holidays are not excluded, because they differ by country — add those yourself if you need them.

Can I add 90 days to a date?

Yes. Choose add/subtract, enter 90 days and pick the start date — the tool gives you the exact resulting date.

Does it handle leap years?

Yes. The calculation uses real calendar dates, so 29 February and months with 30 or 31 days are counted correctly.
