I entered few dates in Column C3 to C20, few of them are duplicates.
How can I count total number of dates (excluding duplicates), duplicates
should be count 1.

Hi,

Try this

=SUMPRODUCT((C3:C20<>"")/COUNTIF(C3:C20,C3:C20&""))

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.
