You are quite correct... it was left over from my testing, when I was trying
to get the individual sections to work correctly. Thanks for noticing that.

Although the original formula works correctly (the double unary, the
minus-minus signs, does nothing more than multiply by one), here is the
corrected formula for the archives...

=4+SUMPRODUCT((WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,1 )-ROW($1:$3))=1)*(DAY(DATE(YEAR(A1),MONTH(A1)+1,1)-ROW($1:$3))28))

Rick,

=4+SUMPRODUCT(--(WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,1)-ROW($1:$3))=1)*(DAY(DATE(YEAR(A1),MONTH(A1)+1,1)-ROW($1:$3))28))

Being as you are multiplying in the SUMPRODUCT() surely you don't need the
double unary?

Here is a formula that, unlike joeu2004's offering, does not require the
Analysis ToolPak and is also not volatile...

=4+SUMPRODUCT(--(WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,1)-ROW($1:$3))=1)*(DAY(DATE(YEAR(A1),MONTH(A1)+1,1)-ROW($1:$3))28))

Try this:

With Dates in A1:A10

This formula counts the number of Saturdays in that range:
=SUMPRODUCT(--(WEEKDAY(A1:A10)=7))

To count other days:
1=Sunday, 2=Monday,....7=Saturday

Does that help?
Post back if you have more questions.
