After clicking Create Assignment you will be taken to the assignment summary page.
All assignment dates relating to this assignment are shown on the Summary page.
To change any of these dates click the pencil icon on the assignment part you wish to edit.
By clicking on the calendar icon the date/time selector will appear. You can use this to edit the Start, Due and Post dates.
The Start Date defines the earliest time a student can make a submission to the assignment part.
This is the final date by which the student should have submitted their assignment. If Late Submissions is enabled then submissions made after the due date will be marked as late.
This is the date when marks/grades will be made available to students. If anonymous marking is enabled (UK only) this is also the date when marks/grades will be shown to tutors in the Grade centre. (They will, however, appear in the assignment’s Submissions Inbox as soon as they are graded, as the student name remains anonymous until the Post Date.)
