Hi: I have two issues somehow related.

1. I am trying to compute the number of days per quarter between an entry
and an exit date. The entry date can be anywhere between 1/1/2001 and
12/31/2005, and so does the exit date.

2. For the same entry and exit dates, I am trying to compute the total
number of days that fall in 2004 and the total that fall in 2005.

Thank you in advance.
