Right click on the sheet tab and select view code. Paste in code like this.
Adjust to react to changes in the appropriate column (as written, the 3 means
the dates are in column 3)

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Count = 1 Then
If Target.Column = 3 Then
MsgBox "update Audit sign off book"
End If
End If
End Sub

If it is a specific range of value only, assume C3:C20


Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Count = 1 Then
If Not Intersect(Target,Range("C3:C20")) is nothing Then
MsgBox "update Audit sign off book"
End If
End If
End Sub

as an example.
