I am aware valid dates in Excel begin 1900-01-01 (Jan 1, 1900), but can anyone explain this? In cell A2, formatted as Text, is the date 1801-07-02. I would have thought my formula to convert that from text to a real date would fail, but it changed it to 3741-07-02 !! I am not picking on Wilson, but I am making use of his formula with one difference. He had: ---copy--- =IF(AND(ISNUMBER(VALUE(LEFT(A1,4))),ISNUMBER(VALUE(MID(A1,6,2)));ISNUMBE R(VALUE(RIGHT(A1,2)))),DATE(LEFT(A1,4),MID(A1,6,2),RIGHT(A1,2)),0) ---End--- I changed it to: =IF(AND(ISNUMBER(VALUE(LEFT(A1,4))),ISNUMBER(VALUE(MID(A1,6,2)),ISNUMBER (VALUE(RIGHT(A1,2)))),DATE(LEFT(A1,4),MID(A1,6,2),RIGHT(A1,2)),0) (I took the semi-colon out and used a comma.) Would my change be responsible for this date changing? I am using Excel XP. Thank you.
