Arithmetic works with dates and displays the results as days, so just multiply the result times 24 to get the approximate number of hours between the dates (Excel default format for dates assumes each day has a full 24 hours). If your oldest date is in A1 and your most recent date is in A2, use the following formula to calculate hours between the two dates: =(A2-A1)*24.If you need to show exact hours between specific times for two dates, just format A1 and A2 to display both date and time (a standard option under cell format for dates SAMPLE: 1/1/09 12:00 AM).
