Set Date Format For Specific Cell In VBA

What I have done is create a macro in Excel and then opened up the VBA editor to make a lot of changes to the initial macro. I am reformatting a whole lot of separate spreadsheets over many workbooks.

Here is the code that is generating the error (Run-Time error '438', Object doesn't support this property or method):

Code:
Range("E2").Select
Selection.Format = "long date"
With Selection
.Font.Size = 11
' .Format = LongDate
.HorizontalAlignment = xlCenter
.VerticalAlignment = xlCenter
End With

As you can see, I first tried the ".Format = LongDate" and did put LongDate in "" which did not work, then I tried the "Selection.Format = ..." after the "Range" statement, and that did not work either. So you will actually know, I am trying to set the format for the cell "E2" to a Long Date format.
