How it works

2. Time between two times

Time calculator: how many hours between two times?

Works for a night shift too. If the end time is before the start time, the calculator counts on past midnight.

22:00 to 06:00 runs past midnight: 8:00 minus a 30-minute break.

3. Working days

Counts the days from the first date up to and including the last, with your working days and the Dutch public holidays. Share the link: the dates are in the address.
