# How to calculate time difference

## How to calculate time difference

(OP)
Hi,

I want to calculate time difference in minutes as follows:

a=DATETIME() && {13/01/2020 02:38:15PM}
b={13/01/2020 02:19:15PM}
c=a-b

The answer is 20 minutes, and the value of "c" is 1116.

Thanks

Abbassaif

Simply subtract one datetime from the other. That will give you the difference in seconds. To get the difference in minutes, divide by 60.

By the way, {13/01/2020 02:19:15PM} is not a valid format for a datetime literal. You want this: {^2020-01-13,02:19:15}
