It's a bit difficult to visualize what you want. Could you attach a small sample workbook to illustrate your problem?

I want to automaticly protect all columns when date is end.

Step 1:

Select all cells that the user should be able to edit in principle.

Press Ctrl+1 to activate the Format Cells dialog.

Activate the Protection tab.

Clear the Locked check box.

Click OK.

Step 2:

Press Alt+F11 to activate the Visual Basic Editor.

In the Project Explorer pane on the left, double-click ThisWorkbook under Microsoft Excel Objects.

Copy the following code into the module:

Private Sub Workbook_Open()
    Dim c As Long
    Dim m As Long
    With Worksheets(1) ' or Worksheets("NameOfSheet")
        .Protect Password:="Secret", UserInterFaceOnly:=True
        m = .Cells(1, .Columns.Count).End(xlToLeft).Column
        For c = 2 To m
            If .Cells(1, c).Value >= Date Then Exit For
            .Cells(1, c).EntireColumn.Locked = True
        Next c
    End With
End Sub

Step 3:

Switch back to Excel.

Save the workbook as a macro-enabled workbook (.xlsm).

Make sure that you allow macros when you open it.
