Your formula works for me. I entered 3/1 (March 1st) in to A2, and got
2008-03-01 in my target cell. So your problem must be you are not entering
the date correctly.

I have use this last year, it's fine until now. the formula is now new to
Ron,
=DATE(YEAR(A2)-1,MONTH(A2),DAY(A2))-(MONTH(DATE(YEAR(A2)-1,MONTH(A2),DAY(A2)))<MONTH(A2))
That is, I enter a month and day in A2 and it will appear as last year's
date, but now nothing changes, still in default year 2009.
Please advise.
