How do I edit an event or assignment in the Calendar?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). This lesson may include two images for specific steps to show the difference between the two designs. Unless otherwise indicated, the functionality and location of the components remain the same. The view available to you is determined by your institution.
You can change the date of an Event or Assignment by clicking on the Event or Assignment or by dragging and dropping the Event or Assignment to a different date. This lesson shows how to edit a calendar item, but you can also delete items from the Calendar. Please be aware that deleting a Calendar entry also deletes the associated content elsewhere in Canvas.
View event details by clicking the event you want to view  and clicking the Edit button .
View assignment details by clicking the event you want to view  and clicking the Edit button .
Drag and Drop Event or Assignment
You can also change the date of an Event or Assignment by dragging and dropping the Event or Assignment to a different date on the month view or mini calendar. Click the Event or Assignment, drag to the new date, and release your mouse.
You can drag and drop undated assignments to and from the month view of the calendar  or mini calendar . Notice the due date of that assignment will change to 11:59pm on that day. Moving events or assignments to the undated items section will remove the date.
