I made a macro on the excel and at the end of the macro I save it on a new
file. Can I put the date when I save the file as part of the file name?

Here is copy the last part of the macro:

ActiveWorkbook.SaveAs Filename:= _
"O:\Shared Services\Finance\2009\IC\IC
Detail\IST_3_1_Update_ddmmyyyy.xls", _
FileFormat:=xlNormal, Password:="", WriteResPassword:="", _
ReadOnlyRecommended:=False, CreateBackup:=False
End Sub
