I don't think I explained my scenario enough.

In Row 1 of Columns B-M, the Column Headings are JAN-DEC, respectively.
Column A, Row 2, the user will enter a date something was done. I want the
"scheduled follow up months" to be automatically highlighted in columns B-M
of Row 2.

If Col A, Row 2 says 1/15/07, I want Col C,Row 2 to be highlighted because
it will correspond with FEB (30 days after the date entered in Col A, Row 2).

I am not sure if I understand your response completely, but it didn't seem
to work. Please let me know if I could have done something incorrectly.

Change your months to dates, starting in col a, as 31/12/06.
Fill across your selection by months (edit, fill, series, col, month)

Select cell b3. Conditional Formatting, select Formula instead of value.
Insert this formula"=AND($A3E$1+1,$A3<=F$1)" and select the colour you want
to use.

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?
