Another problem I've seen with dates and Excel is copying date information from one workbook to another. The problem with this is that the workbooks may be using different underlying date systems. Workbooks originating on a Macintosh use the 1904 date system and Windows defaults to the 1900 date system. Copying dates between workbooks can give you shifted dates. http://support.microsoft.com/kb/180162 http://support.microsoft.com/kb/180162
