Counting hours and minutes
To find the time between two clock times, subtract the start from the end. If the end time is earlier than the start – a night shift from 22:00 to 06:00, for example – the calculator assumes it is the next day and adds 24 hours, giving 8 hours.
Results are shown in hours and minutes, in decimal hours (for timesheets and billing) and in total minutes.
Frequently asked questions
How many hours is 9am to 5pm?
9am to 5pm is 8 hours. With a one-hour unpaid lunch break it is 7 hours of work.
How do I calculate hours for an overnight shift?
Count the hours to midnight and add the hours after midnight. 10pm to 6am is 2 + 6 = 8 hours. The calculator does this automatically when the end time is earlier than the start time.
