Your events calendar's default view is the monthly view:
For calendars that have too many events to display on a single date, Tendenci has a Weekly Calendar function to make it easier to see events.
Hover over the "Events" tab and select "Weekly Calendar"
The calendar will then switch to the weekly view:
You can switch back and forth between monthly and weekly by clicking either the "Weekly Calendar" or "Monthly Calendar" option under the "Events" tab.
