counting specific days from unique records

to add to this query i would like to total those weekdays that are not sundays from unique records.

example

column a

sun 31st Jan
sun 31st jan
mon 1st feb
mon 1st feb
mon 1st feb
tue 2nd feb

the answer would be 2 as there are two unique weekdays that are not a sunday

is this possible

Try...

=SUM(IF(A1:A6<>"",IF(WEEKDAY(A1:A6,2)<7,1/COUNTIF(A1:A6,A1:A6))))

...confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

Hope this helps!
