Holidays in JavaScript (ES5) Gantt control

Non-working days in a project can be displayed in the Gantt control using the holidays property. Each holiday can be defined with the following properties:

  • from: Defines start date of the holiday(s).
  • to: Defines end date of the holiday(s).
  • label: Defines the description or label for the holiday.
  • cssClass: Formats the holidays label in the Gantt chart.

To highlight the holidays, inject the DayMarkers module into the Gantt control.

The following code example shows how to display the non-working days in the Gantt control.
