AdrianXing, you could put =TODAY() in a cell and it will up date, if you
don't want the date to change after you put it in use some code in the
workbook open event to do it, like this

Sheets("Sheet1").Range("A1") = Date

Does anyone know of a function that can make Excel automatically insert
the
current date into a cell when a file is opened up?
