Yes, on column 2, I have something like this:

=DATE(YEAR(A1),MONTH(A1)+8,DAY(A1))

So, column 2 is 8 months older than column 1.

But, on column one is the value and that value is 42217. So, directly on that, how can I know what date it is and how can I add directly the number of months on that date?
