Hi

I am trying to create a car rental spreadsheet for my own use but this one may be abit too complicated for me.

I need the excel to help me to calculate the number of days and hours the car is used.

Example:

pickup car at 12 august 2009 at 9am in the morning
return car at 14 august 2009 at 11am in the morning
Output Total = 2 days + 2 hours rental

The confusing part for me is having the extra 2 hours calculated.

any help?
