Automation Rules that trigger during Company Holidays

We currently have a rule to forward notifications for tickets received during off-hours to a member of the team for coverage. It is currently triggered on weekends or between 5 PM and 8 AM nightly. 

With the holidays approaching, this rule has to be modified to manually add the days in order to continue this coverage. In order to resolve this, we would like the option to trigger notifications and other rules for tickets received on a holiday. The system could refer to Holidays already tracked by the system which measure response time or a custom list of holidays submitted by the administrator. .

Thanks
