Edit All Assignment Dates

You can edit all of your assignment dates at once from your main course page. First, select "Edit Dates" on the left sidebar.

If a date is not applicable to an assignment type, it will be greyed out. Once you have all of your dates set, select "Save Changes". You may also use this screen to mass publish your assignments.  They will not be visible to students until the start date of the assignment has eclipsed.
