Calculated Column that adds 15 minutes to a date

Brass Contributor

I rarely implement calculated columns, but I am in need to do one to add 15 minutes to a StartDate column.  I did this, but it is adding three hours to the result: = StartTimeDate + .625.  Seems like this would be easy, but I must be overlooking something.  Thanks for the information

EDIT: I actually figured it out. It is = StartTimeDate + 15/(24*60)
This is exactly what I needed - thank you!
