In addition to setting a due date for an assignment, instructors can specify a specific date range when students can submit the assignment. These dates are called availability dates. These dates are optional and can be set depending how you want to manage the assignment.

In Quizzes, availability dates may affect student submissions. For more details, view the Quiz availability dates lesson.

Notes:

• Beneath the Due Date and Availability date fields, Canvas will display the time zone date and time according to context. If you manage courses in a time zone other than your local time zone and create or edit a due date for an assignment, the course and local times will be displayed for reference.
• When Multiple Grading Periods are enabled in a course, only due dates are validated against closed grading periods. Availability dates do not apply.
