This demo illustrates how to add and remove holiday events and perform CRUD operations on holiday dates in the Scheduler.
          This sample demonstrates how to perform CRUD operations on holiday dates in a calendar. If a user wants to
            schedule an appointment on a holiday, they should check the Scheduling event on holiday checkbox.
            This will enable them to add an appointment on a holiday date.If a holiday list is displayed in the calendar, the
            Holiday events checkbox will be checked. The holiday list is highlighted in a different color.
          
Scheduling event on holiday
              checkbox is checked, the appointment can be scheduled on holiday dates. If it is unchecked, the appointment
              cannot have CRUD actions performed on it, and a warning message will be displayed.
            Scheduling event on holiday checkbox is
              checked, it allows the event to occur on that dates. If the checkbox is unchecked, it prevents the event from
              occurring, based on the dates in the holiday collection.
