A user brought me a spreadsheet that she inherited from a former employee. In this spreadsheet, the user types in a date value as m/d/yyyy. The spreadsheet converts this to a numerical date. Example: 2/9/2011 will show as 40583. No matter what kind of format we use, (either Date or Custom), we still get the same result. The formula bar shows the date value as 2/9/2011 and if you double click in the cell, it will show the value 2/9/2011. As soon as you remove the focus from this cell it goes back to 40583. Does anyone know what is going on or how to change the cell so that it shows the date format as m/d/yyyy?
