Count by Person how many times Date 1 = Date 2

I am working on a report where I need to count how many times a Date field equals another Date field, for each Person. The data set will contain multiple entries per person, and the Dates will not always match or even have an entry.

I was attempting to use something such as
=COUNTIFS(A:A,"Person A",B:B,"=" &C:C )

But this does not work.

From the example attachment I was expecting a count of 2 entries for Person A, and 1 entry for Person B.

Any help is appreciated to understand how I should approach this, thanks!

Count of person A:

Try this:

Change A12 to read only Person A and A13 to read Person B, then

=SUMPRODUCT(--($A$2:$A$7=A12),--($B$2:$B$7=$C$2:$C$7))

can't compare ranges to corresponding ranges using COUNTIFS/SUMIFS
