Yes there is. Make sure that you have the Analysis Toolpak addin installed. The function NETWORKDAYS returns the number of working days between two dates and it also allows you to specify any holidays.

It seems Jon wants to count Saurdays and Sundays in a given month, say, Nov-2001. If so,
=SUMPRODUCT((WEEKDAY(DATE(YEAR(A9),MONTH(A9),ROW(INDIRECT("1:"&DAY(DATE(YEAR(A9),MONTH(A9)+1,0))))))={1,7})+0)
would do just that.
