Count Month Occurrence in range of date

Hello,

I have a range with dates ( Format 3/25/2010). The range includes different years.
How can I count all rows from March 2010?

Thanks for the help!

If dates are sorted ascending:

You can try this: =COUNTIF(A:A, ">="&"1.3.2010")

Or define cell where you can write any date:

=COUNTIF(A:A, ">="&C1)
