So now I would like to see if I can take this formula one step further.
I now have it set where the formula is just like you said, but I changed the
format.

Time - Duration = Time

Format is now

10/2/08 7:51 AM 14:01 10/1/08 5:50 PM

Now I would like to add days to the Duration.

like this? 02:14:01 where the format is: dd:[hh]:mm

is that posible? or would I need to calculate (# of days * 24) + [hh]

I don't know if I am being clear.

If they are just times:

=IF(B2A2,A2+1-B2,A2-B2)

If they are date and times formatted for time, then use

=A2-B2

In either case, format for time AM/PM.

I need a formula that calculates the like this:

Time - Duration = Time

Formated to look like this

8:10 AM 22:17 9:53 AM

where the duration is [hh]:mm (I think)

so I need to know how to format the cells and the formula.
