Update Due Dates
Due Dates: Update
After selecting the Assignment activity type, all of your course assignments will be listed down the page. Update the due dates as needed, then click on Save changes.
Note: Keep in mind that you don't have to have a date set to begin allowing submissions—as long as the assignment is visible to students, they can submit their work. Similarly, you don't need to indicate a cutoff date or an expected completion date for any assignment.
