I'm trying to calculate the time between the dates , at the beginning the formula was working fine but I've noticed that it does not work when the date is different
For example , I have the following information on cell A1: 09/15/2016 10:00 AM On Cell B2 I have: 09/16/2016 10:00 AM
The formula is just B2-A1 but instead of giving me a result of 24 hours is just giving me 0 . I believe the formula is not recognizing that these are 2 different days and is just doing 10-10
Any idea how to fix this ?

I was able to get the result 24 by setting a custom format of [h] (you will have to type it into the 'Type:' box) on cell C1 while using the formula =B1-A1
The problem with just using =B1-A1 is that if either or both of those cells is not populated then you will get weird numbers in C1. You may want to make C1 display as a blank cell unless both boxes are populated, try something like this =IF(OR(ISBLANK(A1),ISBLANK(B1)),"",B1-A1)
The reason for the weird numbers is that Excel calculates time based on a predefined decimal system that indexes time starting at like 1/1/1900 or something like that. So when manipulating or calculating time, that is something that you always have to keep in the back of your mind.
Hope this helps.

Formation the destination cell to will do but since you have date and time combined it will show as 1 calendar day difference 0 only means that 12 am after the 1 day difference, I know it does not make any sense but its Excel...
If I was you, on column A, I would add the date, and on Column B, the time. then just work with the time, as both combined can be tricky
Don't forget to format your cells!! (right click>Format Cells>Time>3/14/12 1:30 PM)
