Time between two times
Choose Time between two times to work out how long a shift or task lasted. Enter the start time, the end time and the unpaid break in minutes. The calculator subtracts the break and shows the result as hours and minutes and as decimal hours, which is what most timesheets and payroll systems ask for.
| Start | End | Unpaid break | Time worked | Decimal hours |
|---|---|---|---|---|
| 9:00 AM | 5:45 PM | 45 min | 8 h 0 min | 8.00 |
| 8:30 AM | 4:30 PM | 30 min | 7 h 30 min | 7.50 |
| 10:00 PM | 6:00 AM | 0 min | 8 h 0 min | 8.00 |
You can round the result to the nearest 5 or 15 minutes. Rounding rules differ by employer and state, so use the exact figure unless your employer tells you otherwise.

Frequently asked questions
How do I convert minutes to hours?
Divide the minutes by 60. For example, 135 minutes ÷ 60 = 2.25 hours, which is 2 hours and 15 minutes.
How do I add hours and minutes together?
Add the hours and the minutes separately. If the minutes add up to 60 or more, subtract 60 and add 1 to the hours. For example, 2:45 + 1:30 = 3 hours 75 minutes, which is 4 hours 15 minutes.
What is 7.75 hours in hours and minutes?
7.75 hours is 7 hours and 45 minutes, because 0.75 × 60 = 45 minutes.
How do I calculate the hours between two times?
Choose Time between two times, enter the start and end, and subtract any unpaid break. From 9:00 AM to 5:45 PM is 8 hours 45 minutes, and with a 45 minute unpaid break it is 8 hours, or 8.00 decimal hours.
How does it handle a shift that ends after midnight?
If the end time is earlier than the start time, the calculator counts the shift as ending the next day. A shift from 10:00 PM to 6:00 AM is 8 hours. The same start and end time counts as zero hours, not 24.
