About Time Difference Calculator

By using the Time Duration Calculator, one can easily find the actual time difference between two specific points in time (the starting time point and the end time point). In order to use this calculator, you should enter the values of both specific time points in hours, minutes, and seconds. The result will be displayed in absolute time value and standard time format (HH:MM:SS). At the bottom of the webpage you can find some time duration example chart, which can help you understand how this Time Duration Calculator actually works.

Now button will set the starting time to the current time. And the clear button resets the time inputs.

For everyone asking for subtraction. It's the same - you can put the start time in either the first or second field. Just reverse it.

It’s really helpful I’m not gonna lie but I do wish you could add subtraction

Jem 2022-11-19 07:22:33

Such a great app, and very helpful. I just was it let you end at 24 (12 pm) instead of stopping at 23 (11pm).

This site helps so much with school knowing how much longer is left in the period/school day! I do agree it needs a pm and am

Abha 2022-09-13 21:52:56

I don't like this site military time is way too confusing. they should add 2 options

Brad 2022-08-22 11:51:37

Don't Complain about AM/PM. Just add 12 to any time between Noon and Midnight. EX: 5:40 PM = 17:40. "Military Time" is far less confusing when used properly.

Aviva Tessorizse 2022-07-13 16:30:42

I agree, put am and pm. This will make it less confusing

Angaleecka 2022-05-19 14:39:14
