Max,
Thank you for the quick response. The mistake I did was I had C2 formated
as "date" instead of "General". Now it works!

Thanks,

Assuming:

Check-in dates are in col A, A2 down
Check-out dates are in col B, B2 down

and

Length of stay is to be calculated in col C, C2 down

Put in C2: =B2-A2
Format C2 as "General" or "Number" (to zero dp)
Copy C2 down

Col C will return the results you want

How do I write the formula if I want to calculate "length of stay", say
hotel
check-in date was 1/1/2005 and check-out date was 1/10/2005? The answer
is
easy, 10-1=9 days, but when it involves dates, how do you put it in a
formula?
