Hi,

I have a sheet with collums for entry date and exit date used in a car-
compound. I also have a collumn for each month of the year.

What I am trying to do is let excel (VBA) calculate how many days a
car was on the compound in every month. This is a monthly/yearly
ocurring item to check the invoicing.

What I'd like to do is to pull data from our database into the excel
sheet, just the chassis number, entry date and exit date. I would
like to paste this in my excel, and then be presented with the amount
of days a car was on the compound in each month.

Is there any way to this ? I know that if it was a full month, it's
easy to do, but let's say it has an entry on 13.01.06 and an exit on
20.10.06 , then it becomes more complicated. Also the calculation has
to be performed on several thousand cars at once...

Any help ??
