HELP: How to calculate period of time??

[AnnaZ]

Hello,

I have two fields, one contains start date, the other contains end date. Is there a way to construct a third field that would display the number of days between those two fields? For example, start date is 01/04/2004, end date is 01/14/2004, I would need the third field to count and display 10 (10 days).

Thanks in advance for any help.

In the Help Files look up DateDiff function and note that you would use "d" for the units specification.

Thanks for your help. I did not find DateDiff in the help files, although I did see it as one of the functions available. I'm not familiar with this function, but I tried to build this expression for my field:
Expr1: DateDiff ([Date Entered], [Date Left]) , but of course this syntax didn't work. Any suggestions??

Thanks.

Or can't I just do this:
Date Left - Date Entered

Wouldn't this give me the number of days in between?

Try this:
var = DateDiff("d", StartDate, EndDate)
