EXCEL COUNTING HELP

[EXCELably Challenged]

I need to count the number of occurances of a date range from a column of
dates spanning from December 1, 2009 - March 15, 2010. (how many dates in
column C are in the month of december 2009). How do i write a formula that
will recogize the date? thanks

What version of Excel are you using?

Here's one way...

=SUMPRODUCT(--(TEXT(C2:C100,"m/yyyy")="12/2009"))

=COUNTIF(A:A,">="&DATE(2010,01,01))-COUNTIF(A:A,">="&DATE(2009,12,01))

Hello,

=SUMPRODUCT(--(DATE(YEAR(A1:A10000),MONTH(A1:A10000),
1)=DATE(2010,12,1)))
