First you fill date on page load than you will get it. Try this:-

$(document).ready(function() {

          var start = moment().subtract(6, 'days');
          var end = moment();

          function cb(start, end) {
            $('#reportrange span').html(start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY'));
          }

          $('#reportrange').daterangepicker({
            startDate: start,
            endDate: end,
            ranges: {
              'Today': [moment(), moment()],
              'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
              'Last 7 Days': [moment().subtract(6, 'days'), moment()],
              'Last 30 Days': [moment().subtract(29, 'days'), moment()],
              'This Month': [moment().startOf('month'), moment().endOf('month')],
              'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')]
            }
          }, cb);

          cb(start, end);


        //get date_range  
        var date = $('#reportrange > span').text();
        alert(date);

});

Answer 2

The reason, why you getting undefined is $(document).ready and $ (function() { do run at same time and because of that, your daterangepicker may not be properly declared at that time. So, if you want to get the values, you can have them in callback function.

Matter of fact,

daterangepicker startDate and endDate returns moment objects not Javascript Date objects.

 $(function() { var start = moment().subtract(6, 'days'); var end = moment(); var lstart,lend; function cb(start, end) { $('#reportrange span').html(start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY')); lstart = moment($('#reportrange').data('daterangepicker').startDate).toDate(), lend = moment($('#reportrange').data('daterangepicker').endDate).toDate(); console.log(lstart,lend) } $('#reportrange').daterangepicker({ startDate: start, endDate: end, ranges: { 'Today': [moment(), moment()], 'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')], 'Last 7 Days': [moment().subtract(6, 'days'), moment()], 'Last 30 Days': [moment().subtract(29, 'days'), moment()], 'This Month': [moment().startOf('month'), moment().endOf('month')], 'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')] } }, cb); cb(start, end); });

Now, From moment, you can get date in any format. Here is the fiddlelink
