View or include Past Events
With the calendar, you can keep your events in the past viewable on your calendar OR remove them if you don't wish to see them.
To update your viewing preference, click on either Edit Calendar or View Calendar.
Above the calendar grid, you'll see options to view the calendar by Today, List, Week, Month, etc.
Next, you'll see the option to include "Past Events". If the toggle button is not shadowed (off), Past Events will NOT show. If the toggle button is shadowed (on), you will see Past Events (prior to the current date) on your calendar.
You can update your preference at any time by toggling past events on and off.
