Frequently asked questions

How do I add up my work hours?

Enter a start and end time on each row, plus any unpaid break in minutes. The calculator sums every row and shows the total as hours and minutes and as decimal hours for payroll.

Does it handle overnight shifts?

Yes. If the end time is earlier than the start time, the row is treated as crossing midnight and the duration is calculated correctly.

What are decimal hours for?

Payroll and invoicing usually use decimal hours (for example 7.5 instead of 7h 30m). The tool shows both so you can copy whichever your timesheet needs.
