CalendarStream offers a way for you to display your Google calendar or iCalendar on your Roku-connected TV. Installation is very simple: Create a free account on the CalendarStream Website, give the app access to your calendars, go to the CalendarStream app on your Roku for the sync code, and enter that on the website. Return to your Roku, and your Google calendar will be viewable.
The calendar is displayed on your Roku-connected TV in monthly format. Select a day and press the OK button on your remote, and you'll get a detailed list of all events on that day.
If you have multiple calendars, you can add all of them CalendarStream. This is a useful feature if each family member has his or her own calendar, or if you keep work and personal calendars separate. Another useful feature is a task list that sits alongside your calendar. The task list and your calendars can be edited from the Roku; no need to access your calendar directly to make the change.
There is also a free version of this app, with features that appear to be identical to this subscription version.
