duration

Sets the exact duration of a custom view.

Example for a Custom View:

var calendar = new Calendar(calendarEl, {
  initialView: 'timeGridFourDay',
  views: {
    timeGridFourDay: {
      type: 'timeGrid',
      duration: { days: 4 }
    }
  }
});

Simpler example for a calendar with one view:

var calendar = new Calendar(calendarEl, {
  initialView: 'timeGrid',
  duration: { days: 4 }
});

Special Case

If the duration is specified like {weeks:1}, then the dateAlignment will automatically default to start-of-week. However, if it is specified as {days:7}, then no such alignment will happen.

Dynamically Setting

When setting the duration dynamically, it is important to note that it will only affect a generic view i.e. a view without a defined initial duration. Always bear in mind that a view’s duration takes precedence. For example:

var calendar = new Calendar(calendarEl, {
  initialView: 'timeGridFourDay',
  duration: { days: 4 }, // the dynamic setter will change this
  views: {
    timeGrid: {
      type: 'timeGrid'
    }
  }
});

calendar.setOption('duration', { weeks: 1 });

and:

var calendar = new Calendar(calendarEl, {
  initialView: 'timeGridFourDay',
  views: {
    timeGridFourDay: {
      type: 'timeGrid',
      duration: { days: 4 } // the dynamic setter won't change this
    }
  }
});

calendar.setOption('duration', { weeks: 1 });
