When I run the code in this message with {^2003/06/06} and {^2003/06/11} I get 4. What do you get? I sure hope 4!

>>>I see you're trying something like what I posted. I like how you're trying to reduce the code's length. But, given June 11, 2003 and June 6, 2003 your version returns 11 days. Counting the days on the calendar I get 5 days.
