Sorry Guys,

I have looking around on a bunch of websites on calculating days between
dates (sort of) and it's almost working but I need it to really work.

I need a cell to return the number of days a patient was on a ventilator.
Here is my latest try. I get the right number but it's a negative number

=DAYS360(G10,F10)-1

Start Date 1/10/08
End Date 1/18/08

The answer should equal 9. I know the difference between these 2 is 8 but
we count each day the patient is on the vent as if it were a whole day.

So what do I need to do to get this answer from these dates?

Thanks,
Linda
