businessHours

Emphasizes certain time slots on the calendar. By default, Monday-Friday, 9am-5pm.

boolean / object / array. default: false

If true, the default business hours will be emphasized (view live demo). If false (the default), there will be no emphasis.

An object may be given to render business hours with fine-grain control over the days/hours. The object may have any of the following properties:

businessHours: {
  // days of week. an array of zero-based day of week integers (0=Sunday)
  daysOfWeek: [ 1, 2, 3, 4 ], // Monday - Thursday

  startTime: '10:00', // a start time (10am in this example)
  endTime: '18:00', // an end time (6pm in this example)
}

You may also break your business hour declaration into parts, in an array of objects, for additional control:

businessHours: [ // specify an array instead
  {
    daysOfWeek: [ 1, 2, 3 ], // Monday, Tuesday, Wednesday
    startTime: '08:00', // 8am
    endTime: '18:00' // 6pm
  },
  {
    daysOfWeek: [ 4, 5 ], // Thursday, Friday
    startTime: '10:00', // 10am
    endTime: '16:00' // 4pm
  }
]

If you are using one of the resource views from the premium plugins, you may specify business hours on a per-resource basis. See Resource parsing docs for more information.

More information on specifying times can be found in the Duration article.
