Canvas allows you to set a different due and/or availability date for one or more students. You can do this for assignments, discussions, and quizzes. Here's what you need to do:
- Go to Canvas and edit the item.
- Scroll to Assign section at the bottom of the page and click the + Add button.

- Click in the Assign to box and start typing the student's name.
- Click on the name to select it.
- Set the Due, Available from and Until dates for this student.
- There will now be two sets of due dates, one for that student, and one for Everyone Else.

- Click the Save button to save your changes.
