How are days counted?

By default the calculator counts the days between two dates – from January 1 to January 2 is 1 day. With “Include end date” the last day is counted too, as with vacation days.

Business days are Monday to Friday. Public holidays vary by country and region and are not subtracted.

Frequently asked questions

Are leap years taken into account?

Yes, leap years and different month lengths are handled automatically.

Are public holidays subtracted?

No. Business days are Monday to Friday. Holidays depend on your region and need to be subtracted separately.

Can I use dates in the past?

Yes. If the end date is before the start date, the difference is still calculated correctly.
