Time Duration Calculator
Enter a start and end time to get the exact duration in hours and minutes, decimal hours and total minutes — with automatic next day handling for overnight spans.
Enter start and end times to see the duration.
How to use
- Enter the start time and the end time.
- Optionally subtract a break in minutes.
- Read the net duration in hours and minutes, decimal hours and total minutes.
If the end time is earlier than the start time, the end is treated as falling on the next day, which is how overnight shifts and late night events work.
Tips
- If the end time is earlier than the start, it is treated as the next day — handy for night shifts.
- Subtract unpaid breaks in minutes to get the true billable duration.
- Decimal hours (for example 7.5) are what most payroll sheets expect.
