How do I bulk update Canvas due dates?
First, make sure your Modules are all published; otherwise the due dates won't show properly in the Modules and you may have to unpublish the assignment, then republish again.
Open Assignments
In Course Navigation, click the Assignments link.
Open Assignment Dates
On the Assignments page, click the Options icon [1]. Then select the Edit Assignment Dates option [2].
View Assignment Dates
You can view and manage assignment information on the Edit Assignment Dates page. All graded items in your course, including assignments, discussions, and quizzes, are listed in the Title column [1]. Current assignment due dates (if any) display in the Due At column [2], and current availability dates (if any) display in the Available From and Available Until columns [3].
You can also view and edit differentiated due dates for students, sections, and groups [4].
Edit Assignment Dates
To edit an assignment due or availability date, locate the item in the list and click the corresponding date field you wish to update [1]. Type the date in the Date field [2] or select a date from the calendar [3].
Note: When you update an assignment due or availability date, the original due time you selected for the assignment is retained. If no time is set, the due time defaults to 11:59:59 pm for the course time zone, and the assignment is marked late at 12:00:00 am. For example, if you set a due date of September 19 at 11:59 pm, the assignment is marked late if submitted at or after September 20 at 12:00:00.
Save Updated Dates
To save your updates, click the Save button.
View Save Progress
Canvas displays the progress for your updates.
View Update Notification
When your updates save successfully, Canvas displays a Success notification [1].
If there are errors with your changes that prevent Canvas from updating due and availability dates, an Error notification displays [2]. Correct any errors and re-save your changes.
