Not entirely sure i understand your question, but here's something that should be modifiable enough to fit your needs.
The 'datez' is just me generating dates for January and February 2008.
With the query i have asked for the number of days NOT Saturday or Sunday (so working days).
If you need to account for statutory holidays and the like you will need a static table as the last poster suggested.
ME_XE?with
  2     datez as
  3  (
  4     select
  5        to_date('01-jan-2008', 'dd-mon-yyyy') + (level - 1) as my_datez
  6     from dual connect by level <= to_date('01-mar-2008', 'dd-mon-yyyy') - to_date('01-jan-2008', 'dd-mon-yyyy')
  7  )
  8  select trunc(my_datez, 'MM'), COUNT(*)
  9  from datez
10  where to_char(my_datez, 'D') NOT IN (1,7)
11  group by trunc(my_datez, 'MM')
12  /
TRUNC(MY_DATEZ,'MM')                 COUNT(*)
01-JAN-2008 12 00:00                       23
01-FEB-2008 12 00:00                       21
