Transform Your Calendar: Turn Events Into Notifications and Actions! 
Maintenance
- Finally Fixed: Removed unnecessary warning messages when some calendar events don’t have a description (e.g., Google Calendar). Automation behavior remains unchanged.
We updated the default title and message in the start & end inputs to
{{ trigger.calendar_event.get('summary', '') }}
{{ trigger.calendar_event.get('description', '') }}
Thanks to @stephanschleichstr13 for doing the testing

Feature request / patch: “Day Exclude Keyword(s)” (daily blocklist) for Calendar Notifications & Actions
I’m using the Calendar Notifications & Actions blueprint and needed a way to combine the existing keyword triggering with a daily blocklist.
Use case (real example):
- Trigger actions if the calendar event contains shift keywords (e.g.
Early Shift,Late Shift), but only if there is no all-day absence event on the same date (e.g.Vacation,Sick). - In other words: “Include keyword(s)” AND “exclude if any event that day contains X”.
What this patch adds:
- New optional input:
Calendar Trigger - Day Exclude Keyword(s)(comma-separated, like the existing keyword list). - On every trigger (start/end), the automation queries the selected calendar for all events between 00:00 and 24:00 of the trigger date using
calendar.get_events. - If any event on that day contains any of the day-exclude keywords (summary + description), the automation stops immediately.
- The day blocklist is intended to apply always, regardless of whether include/exclude keyword filtering is enabled.
Motivation:
This pattern is very common in work calendars (shifts + all-day vacation/absence). It also enables more advanced automations later (e.g., determining when an EV must be fully charged based on tomorrow’s shift, but skipping charging logic on vacation days).
Note: This patch/diff was AI-generated (with manual testing/iteration in Home Assistant) and may need minor style adjustments to match the upstream blueprint conventions.

Thank you for your consideration
i tried this with another LLM a few months ago and it did not work. this aproach works fine
I just wanted to thank you. This is what I was looking for. I am using this BP to warn me in advance someone’s birthday is coming. Just wanted to ask - is it possible to trigger the notificatiion when ALL keywords are found? For example - when calendar even contains “Kate” and “birthday” - set the trigger for notification “Kate’s birthday is coming!”. I have more people’s birthday in calendar, but only few of them I want to be notified of.
Your welcome, glad you like it.
You will then need to set the keyword you would like to use for the ones you would like to be notified. Maybe you add something like this @birthdaynotification
