<script> 
  calendarInstance.setOptions( {
      manualEditingEnabled: false,
      views: {
          fullMonth: {
              maximumEventsPerDayDisplay: 0
          }
      },
      visibleDays: [ 0, 1, 2, 3, 4 ]
  } );
</script>

      from: new Date(),
      to: new Date(),
      title: "A New Event",
      description: "A description of the event"

      month: today.getMonth() + 1,
