I need to calculate the number of times an item appears within a date range.
Another words, if column A is contains my dates ranging from 1/1/05 - 7/1/05
and column B contains various symbols (ie A, B, C etc.), I need to calculate
how many A's appear between 3/1/05 - 3/31/05. Is ther a formula to use? Or
is there a way to do a combination IF/THEN statement? (If Column A is btwn
3/1/05-3/31/05 then count "A" that appear in column B) I am using Excel 2000.

PLEASE HELP. My brain is goingo n overload!

Hi Diane1477,

Try something like this:

=SUMPRODUCT((MONTH(A1:A100)=3)*(YEAR(A1:A100)=2005)*(UPPER(A1:A100)="A"))

or

=SUMPRODUCT((A1:A100>=DATE(2005,3,1))*(A1:A100<=DATE(2005,3,31))*(UPPER(A1:A100)="A"))

Regards,
KL

Sorry - misprint. The formulae should read as follows:

=SUMPRODUCT((MONTH(A1:A100)=3)*(YEAR(A1:A100)=2005)*(UPPER(B1:B100)="A"))

or

I had a similar need and the this formula worked great. I do have a couple of
questions:

1. Can you have the formula look at two conditions to meet before it
counts. Were there would be (UPPER (B1:B100="A") and (UPPER (C1:C100="B")?

2. The "*" seems to be a form of a seperator, is that correct? It seems to
me that it's similar to using commas, am I correct in that assumption?

Hi!

For question 1:

Just add another array to the formula:

=SUMPRODUCT((MONTH(A1:A100)=3)*(YEAR(A1:A100)=2005)*(UPPER(B1:B100)="A")*(UPPER
(C1:C100="B")))

For question 2:

The "*" is the multiplication operator. What the formula is doing is
multiplying all the arrays together like this:

TRUE * FALSE * FALSE * FALSE = 0
TRUE * TRUE * TRUE * TRUE =1
FALSE * FALSE * FALSE * FALSE = 0

Then summing the result of the multiplication to arrive at a count.
