How to use the hours calculator

In Add and subtract hours, type each period in hours and minutes and choose + or −. The total is shown in hours and minutes, in decimal hours and in minutes — handy for timesheets and overtime.

In Time between two clock times, enter the start and end; if the end is earlier than the start, the calculator assumes it ran past midnight. The break is subtracted from the total.
