you can use the option

$('#calendar').fullCalendar({
            header: {
                left: 'prev,next today',
                center: 'title',
                right: 'month,agendaWeek,agendaDay'
            },
            validRange: {
                start: '2017-05-01',//start date here
                end: '2017-07-01' //end date here
            },
            defaultDate: '2017-05-12'
            });
