The only way I can think of is to use the Worksheet_Change event

Private Sub Worksheet_Change(ByVal Target As Range)
'to store the time in a worksheet.names("ChangeDate")
Me.Names.Add "ChangeDate", Now()
'or
'to write to a catalog sheet using a range for each worksheet name.
Worksheets("Catalog").Range(Me.Name) = Now()
End Sub

It kind of depends upon where you want the information stored.

Is it possible to find out when a worksheet has been
modified within a multiple worksheet excel workbook?
