          drop: function(date) {
              //e.g. starttime="09:00 11:00"
             starttime=$(this).text().split(" ")
             tempDate = new Date(date);
  
             var start=moment(tempDate).format('YYYY-MM-DD');

                allDay: false,
             };
  
  
             $('#calendar').fullCalendar('renderEvent', newEvent, true);

  <p>one of external event sources, i've changed only drop event part like above. because I would like to apply the date by only my <strong>fixed date</strong> via starttime. <br/> 
  but there were created another elements like positioned date and my <strong>fixed date</strong>.
  <br/> do you know how to appear only fixed date? <br/><br/>
  06:00 ~ 08:00 was positioned date.<br/>
  09:00 ~ 11:00 was fixed date.<br/>
  this is my screenshot.
