Represents the fields in the Holiday object that are used by Salesforce Scheduler. A holiday is a period during which your service resource is unavailable for appointment scheduling.
Description: If the Holiday IsAllDay flag is set to true (indicating that it is an all-day holiday), then the holiday due date information is contained in the ActivityDate field. This field is a date field with a timestamp that is always set to midnight in the Coordinated Universal Time (UTC) time zone. The timestamp is not relevant, and you must not attempt to alter it to account for any time zone differences.
