            var d = date.getDate();
            var m = date.getMonth();

            $('#calendar').fullCalendar({
                theme: true,
                header: {
                    left: 'prev,next today',
                    center: 'title',
                    right: 'month,agendaWeek,agendaDay'
                },
                editable: true,
                events: [
                {
                    title: 'All Day Event',
                    start: new Date(y, m, 1)
                },
                {
                    title: 'Long Event',
                    start: new Date(y, m, d - 5),
                    end: new Date(y, m, d - 2)
                },
                {
                    id: 999,
                    title: 'Repeating Event',
                    start: new Date(y, m, d - 3, 16, 0),
                    allDay: false
                },
                {
                    id: 999,
                    title: 'Repeating Event',
                    start: new Date(y, m, d + 4, 16, 0),
                    allDay: false
                },
                {
                    title: 'Meeting',
                    start: new Date(y, m, d, 10, 30),
                    allDay: false
                },
                {
                    title: 'Lunch',
                    start: new Date(y, m, d, 12, 0),
                    end: new Date(y, m, d, 14, 0),
                    allDay: false
                },
                {
                    title: 'Birthday Party',
                    start: new Date(y, m, d + 1, 19, 0),
                    end: new Date(y, m, d + 1, 22, 30),
                    allDay: false
                },
                {
                    title: 'Click for Google',
                    start: new Date(y, m, 28),
                    end: new Date(y, m, 29),
                    url: 'http://google.com/'
                }
            ]
            });
        });
    </script>

This is where the error occour in js file:

(function($, undefined) {


;;

var defaults = {

    // display
    defaultView: 'month',
    aspectRatio: 1.35,
    header: {
        left: 'title',
        center: '',
        right: 'today prev,next'
    },
    weekends: true,
    weekNumbers: false,
    weekNumberCalculation: 'iso',
    weekNumberTitle: 'W',

You probably need to put the jquery reference before the calendar reference. Since you're included it twice, just remove the first reference (the first line of your included code.

<script type="text/javascript" src="../images/HomeImage/PicNews/calendar/fullcalendar.js"></script>
