Course Calendar Tool
You can use the course calendar to provide students with dates for course related events. Course calendar events appear to all members of the course. Common entries include upcoming tests, due dates for assignments, or special lectures. Course items with due dates automatically appear in the course calendar. For more information on using the course calendar, including a video introduction, see this article from Blackboard.
Calendar entries can be viewed across courses by selecting the Calendar option from the Global Navigation area at the top right of the page.
