I am using jquery/1.7.2/jquery.min.js version.

$(document).ready(function () {
//code block of check-in date
 $('#CheckInDate').datepicker({ dateFormat: 'dd/mm/yy', minDate: '0D', numberOfMonths: 2, showButtonPanel: true, onSelect: function () {
     var dateOne = $.datepicker.parseDate('dd/mm/yy', $('#CheckInDate').val());
     dateOne.setDate(dateOne.getDate() + 1);
     $("#CheckOutDate").datepicker('option', 'minDate', dateOne);
     $("#CheckOutDate").show();
     $("#CheckOutDate").focus();
 }
 }); 

 /*Check-Out Date*/
 $('#CheckOutDate').datepicker({
     dateFormat: 'dd/mm/yy', numberOfMonths: 2, minDate: '1D', showButtonPanel: true, onSelect: function () {
         var d3 = $('#CheckInDate').datepicker('getDate');
         d3.setDate(d3.getDate() + parseInt(1));
         $('#CheckOutDate').datepicker('setDate', d3);
         $("#CheckOutDate").datepicker('option', 'minDate', d3);
         $("#CheckOutDate").show();
     }

    $('#CheckOutDate').live('focus', function () {
