Editing assignment due dates
To add, remove, or edit all of your assignment due dates at a glance, click the ellipses ⋮ to the right of your course name, and select "Edit Assignment Due Dates."
To edit the due dates individually, select the calendar icon next to each assignment and select the new date. When you are finished, click "Close." (Changes are automatically saved.)
To adjust the dates for a single assignment, you won't need to open the editor. Instead, click the ellipses ⋮ next to the assignment name and select "Edit Assignment". You will find the "Due Date" adjustable in the assignment settings.
Note, the assignment list will be filtered between assignments with Due Dates and assignments without Due Dates.
