Availability and Due Dates

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 based on how you want to manage the assignment.

Notes:

Beneath the Due Date and Availability date fields, Canvas displays 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 are displayed for reference.
Depending on their notification settings, students will receive a notification if you publish an assignment even if the availability date has not been met.
