Hi, what is "--" before the MONTH function? Do I enter it just like
that? Also, is this an array or a regular function?

Finally, I tried it every way and it won't work - gives either a 0 or a
#NUM! error.

One way:

=SUMPRODUCT(--(MONTH(A1:A365)=2),B1:B365)

Hope this helps

Hi, I have a spreadsheet that has every day of the year (1/1/2004 to
12/31/2004) and I am trying to sum a column next to it to get only
totals for each month. Basically I want to know what I get as a sum
for all of January, February, etc.

So I am trying to use SUMIF in combination with Month(A1:A365)=1
through =12 and just sum those that are in month 1 and then those in
month 2, etc.

Column A has all dates and column B has revenue numbers ($ made that
day)

Can anyone suggest how to do it right?

I was trying arrays like:
for February: {=SUM(IF((MONTH(A:A)=2),1,0)*(B:B))}

I also tried SUMIF such as:
example February: =SUMIF(A:A,MONTH(A:A)&""&"2",B:B)

I know I am doing something utterly wrong but can you please help?

Thanks!
