How to list only weekends events from calendar entity?

Configuration
1

I have linked my calendar with Home Assistant, and correctly got a calendar entity. I can nicely display a list of events within a certain range using the Calendar card.

However, I would like to display a list of events only on the upcoming weekends (e.g events on the next 4 weekends, saturdays and sundays). I know that I can run the calendar.get_events action:

action: calendar.get_events
target:
  entity_id: calendar.my_calendar
data:
  start_date_time: "{{today_at()}}"
  duration:
    days: 100

calendar.my_calendar:
  events:
    - start: "2026-02-19"
      end: "2026-02-21"
      summary: Nursery
    - start: "2026-02-19T18:00:00+00:00"
      end: "2026-02-19T19:00:00+00:00"
      summary: Cleaning

And I can use these events as a variable in templating:

    action:
      - action: calendar.get_events
        data:
          start_date_time: "{{ today_at() }}"
          duration:
            days: 60
        target:
          entity_id: calendar.my_calendar
        response_variable: agenda

      - variables:
          events: "{{ agenda['calendar.my_calendar']['events'] }}"

But Iā€™m not sure how to select only events which fall on weekends.

Can anyone help me here?

I am not the best in jinja, but I would do something like this:

{% set events = agenda['calendar.my_calendar']['events'] %}
{% set ns = namespace(ev_weekend=[]) %}
{% for ev in events %}
{% if as_timestamp(ev.start)| timestamp_custom('%w')|int in (0,6) %}
{% set ns.ev_weekend=ns.ev_weekend + [ev] %}
{% endif %}
{% endfor %}
{{ ns.ev_weekend }}

I believe you need to add the end inside your if also given the first example.

{% if as_timestamp(ev.start)| timestamp_custom('%w')|int in (0,6) or as_timestamp(ev.end)| timestamp_custom('%w')|int in (0,6) %}

Obviously there is still the issue with friday to monday events. Not sure how to deal with that.

By no means a good way of doing it but this could be used.

Loop through the individual days of the event and if that day is 0 or 6 then its true.

{% set start = as_timestamp("2026-02-19T18:00:00+00:00")| timestamp_custom('%w') | int %}
{% set end = as_timestamp("2026-02-24T18:00:00+00:00") | timestamp_custom('%w') | int %}
{{ start}}
{{end }}

if it's past the weekend two loops is needed 
{% if start > end %}
  {% for a in range(start, max(end+1,7)) %} 
    {{a in (0,6)}}
  {% endfor %}
  {% for a in range(0, end+1) %} 
    {{a in (0,6)}}
  {% endfor %}
{% else %}
  {% for a in range(start, end+1) %} 
    {{a in (0,6)}}
  {% endfor %}
{% endif %}

You could get any events that are active over the weekend by finding the weekend dates first then doing a Repeat for each to run calendar.get_events.
