If you really don't care about year, as your post says nothing about that, then

=SUMPRODUCT(--(MONTH(A1:A20)=1))

Would count the number of January dates in the range, if you do care about
year then you could use

=SUMPRODUCT(--(A1:A20=C1),--(A1:A20<=C2))

Where you enter the first day of the month in question in C1 as a date, and
the ending date of that month in C2.
