When Multiple Grading Periods are enabled in a course, assignments are also respected against closed grading periods.
In Course Navigation, click the Discussions link.
Enter a title  and description  for your discussion.
Click the Graded checkbox.

If you submit an invalid string of due dates and try to save the discussion, Canvas generates an error notification. Such invalid entries include not unlocking the discussion before it is due, not placing the due date inside the range of availability dates, or assigning a date that is outside the course or term dates.
Correct the date and then update the discussion again.
