Display next calendar event on a card

Configuration
1

I would like to create a card which diplays the next event on a specific calendar (integrated google calendar), with the time it starts.
I basically wiant to have multiple calendars inside google calendar, for example one for garbage collection days and utility meter reads, one for personal events etc, and display these on individual cards.
Sound like a simple thing, but I couldn’t find any info how anybody would do this and I don’t know where to start.

Not exactly. For the my current use case, I could use Google Tasks, since the “events” were more like tasks if I thought it trough.
I customized the task card for a more compact view:

type: todo-list
entity: todo.household_todo
card_mod:
  style:
    .: |
      ha-card.type-todo-list div.header {
        display: none;
      }
      ha-card.type-todo-list .addRow {
        display: none;
      }
      ha-card.type-todo-list div.divider {
        display: none;
      }
      ha-check-list-item.editRow.completed {
        display: none;
      }
