Day, 3-day and week views split up the days horizontally and hours vertically.

Week agenda splits the screen in 6 equal parts - 5 parts for work days, sixth for weekend. Double-tapping a day will open a list of events for that day. From here swiping left and right allows moving between days.

Month view splits the screen in half with one half displaying a typical month view with color-coded dots next to dates to show which days have events and the other a list of events for the selected day.

Month agenda view lays out all days in a grid and displays all event for the day.

The list view is actually the closest to a typical agenda view despite the name. The difference here is that there are two modes of showing that information - default and detailed. The default mode displays date, time, event name and location (if available) and the detailed mode displays extra information such as what calendar is the event part of, who's attending, notes, etc.

The app will color-code different calendars in different colors as well as allow selecting a different color for each event.
