Automation start and end dates / times

Ability to schedule automations to start and end.

Example: Special Events
This weekend, Memorial Day in Myrtle Beach is extremely busy and the city has implemented special traffic routes for the weekend. 1-way traffic with limited access / egress from the beach. It would be super helpful to setup a special message for guests arriving this weekend to send out at a scheduled time with special directions for the weekend. It would be nice to be able to set this up without worrying that I forget to turn it off on Sun that future guests would not receive this message.

Being on the beach we also have to provide our guests with special notifications for special events such as Hurricanes regarding evacuations, traffic, etc.
