Adding “st, nd, rd, th” to jquery datepicker

Question

How can I add st,nd,rd,th to date format.. i.e. November 19th, or December 2nd, etc.

Currently, I have following code

    $( \"#datepicker\" ).datepi

I realise that this is an old question but I thought I'd post my solution in-case anyone having the same problem finds this post. This method doesn't break the selected date when opening the calendar etc. This uses the format d{suffix} M yy i.e. '30th Sep 2013'

$.datepicker.origParseDate = $.datepicker.parseDate;
$.datepicker.parseDate = function(format, value, settings) {
  if ( $.isPlainObject(format) && format.hasOwnProperty('parse') && $.isFunction(format.parse) ) {
    return format.parse.call(this, value, settings, $.datepicker.origParseDate);
  } else {
    $.datepicker.origParseDate(format, value, settings);
  }
};
$.datepicker.origFormatDate = $.datepicker.formatDate;
$.datepicker.formatDate = function(format, date, settings) {
  if ( $.isPlainObject(format) && format.hasOwnProperty('format') && $.isFunction(format.format) ) {
    return format.format.call(this, date, settings, $.datepicker.origFormatDate);
  } else {
    $.datepicker.origFormatDate(format, date, settings);
  }
};

$('.datepicker').datepicker({
  dateFormat: {
    parse: function(value, settings, originalParseDate) {
      value = value.replace(/[a-z][^\s]+/, '');
      return originalParseDate.call(this, 'd M yy', value, settings);
    },
    format: function(date, settings, originalFormatDate) {
      date = originalFormatDate.call(this, 'd M yy', date, settings).split(' ');
      date[0] += (function(n) {
        n = (+n % 100).toString().split('');
        if (n.length > 1 && n.shift() === '1' || +n[0] > 3) {
          return 'th';
        } else {
          return ['th', 'st', 'nd', 'rd'][+n[0]];
        }
      })(date[0]);
      return date.join(' ');
    }
  }
});
