Determine a date not in the table

Hello, this might be a stupid question, but how would i go about
getting the dates that are NOT in the table.
For instance:
Table contains these dates: like a calendar with sat and sun missing,
but also some of the dates are weekdays too. I need to find out which
date(s) are missing from the list that are Weekends and not the normal
weekdays.
Table
06/01/2007
06/04/2007
06/05/2007
06/06/2007
06/07/2007
06/11/2007
So, the dates missing were the sat and sun (06/02/2007, 06/03/2007)
and the weekday 06/08/2007.
How would i create a query to find the missing dates?
Thanks for any insight or suggestions.

You'd have to have a table of all potential dates and then do a left join
from it to the other table, filtering on where the PK of the other table is
null.
