I have column A with a date mm/dd/yyyy.
Column B is JAN, Column C is FEB, and so on.

If column A includes a date in JAN, I want the cell for Column C (FEB) to
highlight. In other words, the cell will need to be filled 30 days after the
date entered.

With the unique style of formatting for dates, I can't figure out how to
identify if cells include certain dates, etc. Any ideas?
