I found a wonderful solution to counting business days including holidays at
www.dbforums.com/t981086.html.  The solution is to create a table storing
all calendar dates, indicating which are business days and holidays, like
this:

Calendar table:
caldate        wkday   holiday
2004-02-01   1
2004-02-02   2
2004-02-03   3
2004-02-04   4
2004-02-05   5
2004-02-06   6
2004-02-07   7
2004-02-08   1
2004-02-09   2
2004-02-10   3
2004-02-11   4
2004-02-12   5
2004-02-13   6
2004-02-14   7
2004-02-15   1
2004-02-16   2   President's Day
2004-02-17   3

Then create a query like this:

select count (*)
from Calendar
where caldate between current_date and 'yourdate'
and wkday in (2,3,4,5,6)
and holiday is null

It works perfectly! And being that I sweat bullets when I look at
complicated code, it is perfect for me...
But I'd like to query it in a slightly different way...in my company, we
need to know what is 5 business days from today.  So in the above example,
if today was 2004-02-09, 5 business days in the future would return the
result 2004-02-17.

Can anyone help?  You could be my new personal hero!
