Simply subtract the earlier date from the later date, and format the cell as a number with as many
decimal places as you want. One day in Excel is 1, two days is 2, etc.
Thanks, but I'm trying to get the format of the cell to be shown as [d]:hh:mm,
not a number with a decimal. When I enter this I get an error, but it works
for [h]:mm:ss. Why won't it work for days?
