Try something like this:

With dates in A1:A100

This formula counts the number of Saturdays
=SUMPRODUCT(--(WEEKDAY(A1:A100)=7))

Or....if some of the cells may be blank:
=SUMPRODUCT(--((A1:A1000)*(WEEKDAY(A1:A100)=7)))
Does that help?

Hi,

I need to count the number of Saturdays in an array of dates. I used the
following approach, which didn't work. Does anyone have another idea?

{=SUM(IF((WEEKDAY(array1,2)=7),1,0))}

Thanks!
