Excel Formula

Sub Sample()
    Dim MonthNm As String
    MonthNm = "September"
    Debug.Print Month(DateValue("01 " & MonthNm & " 2012"))
End Sub

or

Sub Sample()
    Dim MonthNm As String
    MonthNm = "September"
    Debug.Print Application.Evaluate("=MONTH(1&" & Chr(34) & MonthNm & Chr(34) & ")")
