If you just want to see if a date in Column A is contained anywhere in
Column B then try:

=SUMPRODUCT(--(A1=$B$1:$B$21))

This will return 1 for matches and 0 for non-matches

If you want Same.Different then use:

=IF(SUMPRODUCT(--(A1=$B$1:$B$21)),"Same","Different")

Thank you, that formula was very helpful. However, maybe I didn't
explain
myself., Perhaps a different formula would work better. I don't need to
have identical dates in each row. (What happens with your formula, is
that
the first time the dates don't match, it continues down saying
"different"
even though the rest of the dates match, because the identical dates are
not
in the exact same row.
I hope this is clear.

Thank you!

You can enter a formula like this in a column next to your two
columns:

=IF(A1=B1,"same","Different")

and copy down. You can then investigate the "Different" cells more
thoroughly, maybe by means of a filter.

Hope this helps.

Hello again. How do I compare data in two columns?

Both columns contain dates. Both columns should be identitcal,, but
if
they are not, I need excel to highight, or to otherwise let me know
which
dates are not identical in both columns.
