Hi. I love your blueprint and am using it to load a holiday calendar to shift my trash day. I have it set up to run on the first of the year (which it just did), and I just got an error message:

  Detected use of deprecated service `calendar.list_events`
  Use calendar.get_events instead which supports multiple entities.

  Please replace this service and adjust your automations and scripts and select submit to close this issue.

I'm going to look to see if I can fix the blueprint for my own use, but wanted to put it out there so if you are still managing the blueprint you may want to address

Hi. I have never used this actually. If you figure it out, feel free to send the corrected version, so I can fix it for the otherts.
Also, Holidays is becoming part of Home Assistant core in January, so there will be no point maintaining a custom integration with the same functionality. So it might be worth updating the scripts to work with the native integration.

I was able to modify the blueprint to get it to work, but it does require a hack that I am not happy with.

I replaced all list_event calls with get_event calls.

I then changed lines of code as follows:

• variables:
  holiday_dates: |-
  {%- set ns = namespace(dates={}) %}
  {%- if holidays["calendar.us_holidays"]["events"] %}
  {%- for event in holidays["calendar.us_holidays"]["events"] %}
  {%- set ns.dates = dict(ns.dates, **{event.start:event.summary}) %}
  {%- endfor %}
  {%- endif %}
  {{ ns.dates}}
  destination_dates: |-
  {%- set ns = namespace(dates={}) %}
  {%- if destination["calendar.trash_days_offset_for_holidays"]["events"]%}
  {%- for event in destination["calendar.trash_days_offset_for_holidays"]["events"] %}
  {%- set ns.dates = dict(ns.dates, **{event.start:event.summary}) %}
  {%- endfor %}
  {%- endif %}
  {{ ns.dates}}
• repeat:
  for_each: '{{ source["calendar.trash_days"]["events"] }}'

in general, instead of say source.event, you now need to use: source["calendar.trash_days"]["events"]

The hack I used is I hard coded the calendar name in the blueprint (like above "calendar.trash_days". there should be a way to use the passed variable: "{{ source_calendar }}", "{{ destination_calendar }}" and "{{ public_holidays }}" which translated to the hardcoded calendars I used, but try as I might, I could not properly modify the code to work.

bruxy70, feel free to use the above to modify your blueprint if you wish, and if you obviously know how to use the proper variables, vs the hard coded values, that would make it a true blueprint again.

Okay. sorry, totally fixed. I learned that I was nesting templates.

the proper solutions for above is to do:

{%- for event in holidays[public_holidays]["events"] %}

{%- for event in destination[destination_calendar]["events"] %}

and

for_each: '{{ source[source_calendar]["events"] }}'

The full code which appears to be working now is below:
template above

Thanks for this contribution, I have updated the blueprint to this.
