    header: {
        left: 'prev,next today',
        center: 'title',
        right: 'month,basicWeek,basicDay'
    },

    defaultView: 'month',

    dayRender: function (date, cell) {
       var check = $.fullCalendar.formatDate(date,'yyyy-MM-dd');
                    var today = $.fullCalendar.formatDate(new Date(),'yyyy-MM-dd');
                    if (check < today) {
                        cell.css("background-color", "red");
                    }
    }
});
