I have a formula for calculated column which gets the date difference in hh:mm format.


But I want to get the difference in just minutes. I created very complex formula and they didn't work. For example:


Please help me about getting the difference in minutes.

The result that I expect:

1/15/2014 16:35 1/15/2014 16:45 The result should be 10.

1/15/2014 7:00 1/15/2014 7:00 The result should be 0.

  • Did you try what I suggested? I updated my answer to show that it works exactly as you expect

  • Ow I'm so stupid. I forgot to change the return type as number from date time format. It didn't work with the 1440. but what I wrote is worked. Thank you anyway.

According to this link it should be easy.

Try this:

=([COLUMN2] - [COLUMN1])*1440

This will return the total number of minutes between the two dates


enter image description here

  • It looks like it should work correct. But gives me this kind of results 12/20/1899 0:00.

  • What data type did you set for the calculated field? It must be a number not a date

  • It's date. Not number. 1/15/2014 21:30. So what should I do?

    The formula returns a number. The data type for the calculated column must be a number. How could a number representing a time span in minutes be converted to a date?

  • this formula returns the difference in the minutes unit between two times, not the total number of minutes between the two dates

i think the key here is to get the full ammount of minutes in a day, col 1 is the start date and col 2 end date


this should work!


above was taken from link below but converted to work in sharepoint!

06/09/2007 10:35 AM vs 06/10/2007 3:30 PM


Total minutes between two times (1735)


  • But how can this get the difference ?
