Time between two times
Enter a start and end time (24-hour clock) to get the duration in hours and minutes, in decimal hours and in minutes. If the end time is earlier than the start, the tool assumes it is on the next day and says so.
| From | To | Duration | Decimal |
|---|---|---|---|
| 08:00 | 16:30 | 8 h 30 min | 8.50 |
| 22:00 | 06:00 (next day) | 8 h | 8.00 |
| 09:15 | 13:45 | 4 h 30 min | 4.50 |
Adding time
Enter a time and a duration, then choose Add or Subtract. The tool shows the resulting time and whether it falls on a later or earlier day: 22:00 + 3 hours = 01:00 the next day. Long durations such as 50 hours work too.
Minutes to decimal hours
Divide minutes by 60: 15 min = 0.25, 30 = 0.50, 45 = 0.75, 20 ≈ 0.33. So 7 h 45 min is 7.75 hours.
This tool handles clock times only. For spans across several days, count the days with Date Difference and add the hours; for office days in a period, use the Working Days Calculator.
