Holiday
The Holiday integration allows you to create a calendar of holidays in Home Assistant for powering automations.
It uses the Python module holidays
A calendar entity has a state and attributes that represent the next upcoming event (only). A calendar trigger is a much more flexible way to power automations with fewer limitations than using the entity state.

Holiday calendar automations
Individual holiday Events are what powers automations such as:
- Turn on the Christmas lights at the start of Christmas Day.
 - Prevent your covers from being opened on public holidays.
 
For an overview, refer to calendar automations. You can use calendar trigger variables in a condition or action such as the event summary, description, location and in other places.
