Column A has an Employee Name
Column B has a Date

An employee name can repeat on the same date

I want to know by month the sum of the count of the number of unique names each day.

Excel Facts

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.
Sort by date Sort by votes
This is an array formula and must be entered with CTRL-SHIFT-ENTER.
Also, I think your May count should be 2 in your example.

Drag formula down as needed.

I added a helper column and copied down:

=IF((COUNTIFS(A$1:A1, A1, B$1:B1, B1)/COUNTIFS(A:A, A1, B:B, B1))=1, 1, 0)

Then I sum'd the helper column if I matched the date range in column B
