Associating a Holiday List to Business Hour

Business hours can be associated with holiday lists to ensure tickets, SLAs or pending activities are escalated only during the operational hours that can prevent delays due to unavailability of support agents. The days that are marked as holidays will be excluded while setting due dates and triggering escalations for SLAs, Blueprint, and time-based rules. You can create holiday schedules for multiple regions or time zones for eg., US holiday list, UK holiday list,  Australia holiday list, etc. which can be associated with the respective business hours. 

Note

1. A business hour can be associated with only one holiday list.
   
2. A holiday list can be associated with more than one business hour.
