Not Open Excel File After Fixed Date!

Not Open Excel File After Fixed Date!
I got a VB code, from our forum. However, want to make modify as per following.

Currently, If I put to save excel file all other sheets (except sheet 1) are hidden. (before expire)

I do not want to be hidden until Excel File expires, by his expire in date like here 2009,01,10

Code:

Private Sub Workbook_Open()
    Dim i As Integer
       If Date <= DateSerial(2009, 1, 5) Then
   
        Application.ScreenUpdating = False
        ThisWorkbook.Unprotect Password:="___"
        
        For i = 2 To Worksheets.Count
        
            Worksheets(i).Visible = True
        Next i
        ThisWorkbook.Protect Password:="___"
        
        Application.ScreenUpdating = True
    Else
        MsgBox "This file cannot be accessed after Jan. 05, 2009."
    End If
End Sub

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
    Dim i As Integer
    
    Application.ScreenUpdating = True
    ThisWorkbook.Unprotect Password:="___"
    For i = 2 To Worksheets.Count
    
        Worksheets(i).Visible = xlVeryHidden
    Next i
    ThisWorkbook.Protect Password:="___"
    Application.ScreenUpdating = True
End Sub
