Delay password protecting a file

[cheesey]

For added security I'd like to put in a password that protects the workbook that only comes up after 1 or 3 months, is this possible?

Thanks in advance

Maybe look at the workbook open event?

Private Sub Workbook_Open()
If Now > 42298 Then
    ThisWorkbook.Protect Password:="SpongeBob"
End If
End Sub
