Same principle:

**((**:Column 4 + :Column 3**)** - **(**:Column 1 + :Column 2**))** / **60** / **60**

The date/time value internally represents nr of seconds since a reference date. Simply substract the the columns and divide with 3600 to get the result in hours.

(:Column2-Column1**)**/**60**/**60**

But the Date is one column and Time is in another column. Sorry, I represented my data wrong in the above example. It actually looks like

Column1 Column2 Column3 Column4

01/30/2013 5:30 02/02/2013 14:30

here column1 and column 2 is one set . Example, jan 30th 5:30 AM is represented by column 1 and column 2.

Feb 2nd 14:30 PM is represented by column 3 and column 4. Now I want to know how many hours are in between Feb 2nd 14:30 PM and Jan 30 5:30 AM.

Thanks,
