This subtract time calculator is an essential tool used to find the difference between two given times.
It’s particularly useful in various scenarios such as calculating work hours, time spent on tasks, or determining durations between events.
For example:
- If you start work at 9:00 AM and finish at 5:30 PM, the calculator would subtract these times to give you 8 hours and 30 minutes.
- If a flight departs at 10:15 AM and arrives at 2:45 PM, the calculator would determine the flight duration as 4 hours and 30 minutes.
Subtract Time Calculator
| Start Time | End Time | Calculation | Time Difference |
|---|---|---|---|
| 9:00 AM | 5:30 PM | (1760+30) – (960) = 1050 – 540 | 8h 30m |
| 11:45 AM | 2:30 PM | (1460+30) – (1160+45) = 870 – 705 | 2h 45m |
| 3:20 PM | 7:05 AM | (760+5 + 1440) – (1560+20) = 945 | 15h 45m |
| 8:15 PM | 12:45 AM | (060+45 + 1440) – (2060+15) = 270 | 4h 30m |
| 1:30 PM | 4:45 PM | (1660+45) – (1360+30) = 1005 – 810 | 3h 15m |
| 6:00 AM | 10:30 AM | (1060+30) – (660) = 630 – 360 | 4h 30m |
| 12:00 PM | 3:15 PM | (1560) – (1260) = 195 – 720 | 3h 15m |
| 5:00 PM | 9:00 PM | (2160) – (1760) = 1080 – 1020 | 4h 0m |
| 7:45 AM | 11:15 AM | (1160+15) – (760+45) = 675 – 465 | 3h 30m |
| 4:00 PM | 8:30 PM | (2060+30) – (1660) = 510 – 960 | 4h 30m |
| 9:30 PM | 2:00 AM | (260) – (2160+30) + 1440 = 120 – 1290 | 4h 30m |
| 10:00 AM | 12:00 PM | (1260) – (1060) = 720 – 600 | 2h 0m |
| 3:00 PM | 6:45 PM | (1860+45) – (1560) = 1005 – 900 | 3h 45m |
| 1:15 PM | 5:00 PM | (1760) – (1360+15) = 300 – 795 | 3h 45m |
| 2:30 PM | 7:30 PM | (1960) – (1460+30) = 450 – 870 | 5h 0m |
Subtract Time Formula
The formula to subtract time involves converting both times (seconds or minutes) and then finding the difference:
Time Difference = End Time - Start TimeIf the result is negative, add 24 hours (86,400 seconds or 1,440 minutes) to get the correct time difference.
How to Subtract Time?
To find the time difference between 10:30 AM and 2:15 PM:
- Convert to minutes since midnight:
- 10:30 AM = (10 60) + 30 = *630 minutes
- 2:15 PM = (14 60) + 15 = *855 minutes
- Subtract: 855 – 630 = 225 minutes
- Convert back to hours and minutes:
- 225 minutes = 3 hours and 45 minutes
The time difference is 3 hours and 45 minutes.
- Convert both times to a common unit (seconds or minutes since midnight).
- Subtract the start time from the end time.
- If the result is negative, add 24 hours.
- Convert the result back to hours, minutes, and seconds if necessary.
