Try =MOD(B3-A3+D3-C3,1)
though I'm surprised that you're getting a #NUM! from =B3-A3+D3-C3, as it
normally shows a ####### if you get a negative time.

Thanks a lot for your help. The only place I am still getting an error is
when the time goes from PM to AM. Here is what I input:


6:47 PM 11:08 PM 11:55 PM 4:38 AM #NUM!

I'm assuming I am getting the error because it is subtracting the AM from
the PM at the end. Is there any way to avoid this?

Thanks again for your assistance.

Format the inputs as times (this is as simple as entering a number, a
space,
and am or pm), then use a little math. This formula calculates the
elapsed
time:

=B3-A3+D3-C3

assuming the entered values are in A3 to D3. E3 will also have a format
of
0:00 AM/PM. Select the cell, go to Format menu Cells, and on the number
tab, choose a time format without am/pm.

I have time sheets that people fill out and and calculate by hand. I
would
like to insert a formula that will calculate the hours and minutes
worked.
An example would be:

Time In Time Out Time In Time Out # Hours
8am 11am 12pm 5:30pm 8.5


It would be even better if I could get "8 Hours and 30 Minutes" instead
of
just "8.5." I'm thinking the only way to do this would be to use army
time
because the am or pm will just get in the way of the calculation, but
if
it
is possible to leave that would be great as well.

Thanks in advance for any assistance! Let me know if there is any
additional information needed.
