Count According to Date

[Lori]

I need a formula that will count the number of occurances a month/year occur.
I have a column with dates mm/dd/yy. I have another column with mm/yy to
represent closings. Any help is appreciated!

A B C
Plan Elevation Projected Close - Year
2636 C Dec-05
3572 C Dec-05
3356 A Jan-06
3572 C Dec-06
2896 A Feb-06

Closings answer should be
Dec-05 2
Jan-06 1
Feb-06 1
Mar-06 0

=SUMPRODUCT(--(TEXT($A$2:$A$20,"yymm")=TEXT(M1,"yymm"))

where M1 holds the test date
