Counting Dates

[MikeG]

I would like to count the numbers of entris in a column that have the same
month and year. Each value has a date defined as mm/dd/yyyy.

Ex. how many entries are there for January 2007?

do I use countif?

 

[Don Guillett]

=sumproduct((year(a2:a22)=2007)*(month(a2:a22)=1))

 

[Gaurav]

for january =COUNT(IF(MONTH($A$1:$H$1)=1,$A$1:$H$1))

press CTRL+SHIFT+ENTER not only ENTER

For feb change 1 to 2 in the formula and so on...change the range as per
your need.

hope this helps.

Try something like this:

=SUMPRODUCT(--(TEXT(A2:A100,"yyyymm")="200701"))

Is that something you can work with?

But that will include all January dates, not just 2007.
