When your calendar contains events at several venues, use the venue filter in the card view to focus on the events you need. Your selection is saved for the next time you open the calendar.
In this article you will learn how to filter calendar cards by venue
Let's get you started
Open Calendar and switch to the card view if needed. Open Venues beside the Active/All switch. Select one or more Venues by name. The cards update after a brief pause to show only events at those venues.

Choose All in the venue list to show every venue again. The Active/All switch continues to filter event status separately. Your venue selection is remembered when you return to the calendar.
