Clock Duration Calculator

To find the clock time duration, all you need to do is subtract the start time from the end time. You can do it easily with our calculator. If you want to learn to do it by hand, here is an example.

Let's say you want to find time between 7:48 am and 4:13 pm.

1. First, convert the pm time to a 24-hour format. 4:13 pm becomes 16:13.

🙋 If you're using our clock duration calculator - you don't need to do that. Just set the 12-hour mode, and you can input the am/pm times.

2. Subtract the start time from the end time:

   16:13
-7:48
-----
??:??

   That's a bit tricky to calculate - the amount of minutes in the end time is less than in the start time. You need to convert one of the hours in the end time to 60 minutes (16 hrs 13 min equals 15 hrs 73 min).

   15:73
-7:48
-----
08:25

3. The clock time duration in this example is 8 hrs and 25 min.

To use our clock duration calculator, you only need to do three things:

1. Choose clock format. You can choose a 12-hour (am/pm) or a 24-hour one.
2. Enter the start clock time.
3. Enter the end clock time.

The clock duration time will appear in less than a second!
