Time Calculator
Add and subtract times, find the hours between two times, and total work hours.
Enter whole numbers only.
The end time is on the next day.
Check the start, end, and break. A break cannot be longer than the shift.
Time Calculator
The time calculator handles three everyday jobs. Add and subtract durations such as 1:30 + 0:45, find how long it is between two clock times, and total the hours you work in a week after breaks.
Results are shown as hours and minutes and as decimal hours. Timesheets and payroll often need decimal hours, where 7 hours 30 minutes is 7.5 hours.
decimal hours = hours + minutes ÷ 60
How to use
- Add and subtract: type hours, minutes, and seconds in each row. Click the + or − button to switch a row between adding and subtracting, and add up to 10 rows.
- Between two times: choose a start and an end time. If the end is earlier than the start, it counts as the next day, so 22:00 to 06:00 is 8 hours.
- Work hours: enter start, end, and break minutes for each day. Leave a day empty for a day off.
