I can't vertically align element to bottom

$(document).ready(function() {

    // page is now ready, initialize the calendar...
    var eventsArray = [
            {
                title: 'Test1',

            },

                start: new Date("2015-04-21")
            },
            {
                title: 'Test3',
                start: new Date("2015-04-21")
            }
        ];

    $('#calendar').fullCalendar({
        // put your options and callbacks here

            left: 'prev,next', //today',
