Work hours calculator
Enter clock-in, clock-out and break time for each day: get the total in hours and minutes and in decimal hours, ready for your timesheet.
Hours and minutes vs. decimal hours: what's the difference?
A time card shows hours in hours:minutes format (7:30 means seven hours and thirty minutes), but payroll systems, invoices and spreadsheets almost always use decimal hours, where 7:30 becomes 7.5 because 30 minutes is half an hour. To convert, divide the minutes by 60: 15 minutes = 0.25 hours, 20 minutes = about 0.3333, 45 minutes = 0.75. This tool does the conversion for you and adds up all your days, so you avoid the classic mistake of adding 7:45 and 7:30 as if they were decimal numbers (14.75) when the answer is 15:15, that is 15.25 hours.
Breaks and overnight shifts
Enter your break in minutes and it is subtracted from the time between clock-in and clock-out. Rules vary, in the US there is no federal requirement for meal breaks, but many employers and some states provide a 30- or 60-minute unpaid lunch, which is why unpaid break time usually comes off your total. If the clock-out time is earlier than the clock-in time (for example in at 10:00 PM and out at 6:00 AM), the calculator automatically treats it as an overnight shift that crosses midnight.

The other hours pages read and write durations the same way: Add hours and minutes, Difference between two times, Time unit converter and Duration converter (hh:mm:ss). On all of them 1:30, 1.5 hours and 90 minutes are the same duration, and the same duration gives the same numbers.
