Converting String into date format in JS

var value = $.datepicker.parseDate("dd-M-yy",date);
return $.datepicker.formatDate("dd\mm",value);

$('.date').each(function(idx,elt) {
  var value = $.datepicker.parseDate("dd-M-yy",$(elt).html());
  $(elt).html($.datepicker.formatDate("dd\mm",value));
});

    String newdate="Tue Mar 04 16:58:00 GMT+05:30 2014";

    SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd hh:mm:ss z yyyy");

    try {
     Date d = sdf.parse(newdate);
    } catch (ParseException e) {
        e.printStackTrace();
    }

var a = '25/01/2014';
var b = a.split('/');
var d = new Date(b[2],b[1],b[0]);
