The Upcoming events block displays module, group or user events month-by-month. Due dates for assignment and quizzes etc., as well as Scheduler appointments, will appear in the Upcoming events block automatically.
The Upcoming events block is added by default to modules using City Course Format and Grid format so does not need to be added. You can add this block if you are using an alternative course format.
To view events across all modules, access the Calendar from the Block drawer on the Dashboard page.
