How Compute # of Days between Two Dates?

[W. eWatson]

That's the question in Subject. For example, the difference between 
08/29/2008 and 09/03/2008 is +5. The difference between 02/28/2008 and 
03/03/2008 is 4, leap year--extra day in Feb. I'm really only interested in 
years between, say, 1990 and 2050. In other words not some really strange 
period of time well outside our current era of history.
