Date fomula not working
At one stage you told us that G2 contained 39508.
If you format that cell as date you will get 3-Jan-2008, as required. Also, Rick Rothstein suggested a much simpler formula giving the same result: =A2-365-(DAY(A2)<DAY(A2-365)) -- Kind regards, Niek Otten Microsoft MVP - Excel "FangYR" wrote in message ...
