I am trying to set up a formula to count the number of data occurances each
quarter. I currently am using the function :

=COUNTIF('Tower Age'!B6:B80,"12/31/2005")

but that only gives me the occurances of that date.

How can I use the countif function (or any other function) to evaluate a
range of data from the 4Q: 10/01/2005-12/31/2005 and receive a count of all
the data in that falls in that range?

Thank you.
Philip

=SUMPRODUCT(--(MONTH(B6:B80)=10),--(MONTH(B6:B80<=12)))

for Q4, or maybe

=SUMPRODUCT(--(INT((MONTH(B6:B80)-1)/3)+1=4))

=SUMPRODUCT(--('Tower Age'!B6:B80=DATE(2005,10,1)), --('Tower
