Users can scroll to view the entire list.\nScrolling allows the user to view events for today and tomorrow\n\nUsers can see two kinds of events:\n\n- Scheduled events, with start and end times\n- All-day events\n\nBy default, users automatically see scheduled events for each day, while the\nlist of all-day events for each day is initially collapsed.\n\nIndividual events include a description and duration, and may optionally provide\nan event location and phone number. See [event anatomy](/cars/design/automotive-os/apps/calendar/anatomy#anatomy-of-an-event-listing) for a detailed description of an event listing. Users can [navigate to events](/cars/design/automotive-os/apps/calendar/interaction-model/overview#navigating_to_an_event) that include location, and they can [dial in to events](/cars/design/automotive-os/apps/calendar/interaction-model/overview#dialing_in_to_an_event) that include a phone number.\n| **Note:** If there are no scheduled events on a particular day, users see *No scheduled events. You're free!* for that day.\n\n### Viewing all-day events\n\nTo view the list of all-day events for a particular day, users can select the\nexpand button at the right side of the collapsed list. Expanding an all-day\nevent list pushes scheduled event content down.\nExpanding and collapsing an all-day events list\n\nTo hide an expanded list of all-day events, users can select the collapse button\nat the top right side of the expanded list.\n\n### Viewing declined events\n\nDeclined events that users did not delete from their scheduling apps on their\ncompanion devices will appear in Calendar in dimmed, strikethrough text. If a\ndeclined event includes a location, however, the user can still [navigate to the event](/cars/design/automotive-os/apps/calendar/interaction-model/overview#navigating_to_an_event), and if the event includes a phone number, users can still [dial in to the event](/cars/design/automotive-os/apps/calendar/interaction-model/overview#dialing_in_to_an_event).\n\nNavigating to an event\n----------------------\n\nTo navigate to an event that includes location information, such as a street\naddress, a user can select the body of the event listing or select the event's\nnavigation affordance.\nSelect event location or navigation icon to navigate to an event\n\nCalendar automatically starts the user's Android Automotive navigation app and\npasses the event location information to the app.\n\nDialing in to an event\n----------------------\n\nTo dial in to an event that includes a phone number, a user can select the\nevent's phone affordance.\nSelect the phone icon to dial in to an event\n\nCalendar automatically starts the Android Automotive [Dialer](/cars/design/automotive-os/apps/dialer/overview) app and passes the phone number to the app."]]
