Calendar in Landscape Mode

[Android Central Question]

Galaxy S7 - when viewing the calendar and I change the phone from portrait to landscape, the sidebar to the right which contains the day's events won't vanish. I turn the calendar to landscape and like to view the calendar as is, with all the events listed in the box for each day. How can I disable this side bar? The main reason I switched to Android was to be able to view the calendar in month view in landscape mode.... so I'm frustrated that it doesn't work as I anticipated. If this can't be fixed, is there another calendar app that shows the whole month in landscape mode?
