How to Count Dates in 2 Lists

[foofoo]

Hello -

I have 2 columns and each contains a list of dates. Is there a
formula I can use to show how many times each date in column A appears
in the list in column C? I would like to see the results in Column B,
and an example of what I am looking for is shown below.

Column A Column B Column C
12/21/08 3 01/01/07
0/01/08 0 12/21/08
01/02/09 1 12/21/08
01/03/09 0 01/02/09
01/01/07 1 12/21/08


Thank you!
