Automation for holidays

I want to create an extra automation for holidays, such as Christmas, Ascension Day, Pentecost, etc.
I have installed the holiday integration.
Can someone tell me how I can also create an automation for this in the visual editor.
Possibly also in Node Red

You can use Calendar triggers, see this

Hello Ronald,

Or this:

Gentlemen, thanks for your answer, but I still prefer to work with the visual editor.
I have now installed Google Calendar in HA.
But when I select the calendar in question I can’t find an event input field. (see attachment) what’s wrong here.
Or do I have to do everything with yaml?

The Trigger is for any event in the calendar. You can use the template {{ trigger.calendar_event.summary }} to distinguish which event by summary/title.
