for example
var culc = new CultureInfo("ja");
culc.DateTimeFormat.AbbreviatedMonthNames
Will return string[13] { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "" }
Is there a more elegant way of determining if currentculture has proper abberviated names or they just contain numbers, without having to just check the first element to determine if its a number or not
