When you are enrolled in a continuous-enrollment course, the system automatically schedules suggested due dates for all gradable activities based on various factors to help you keep up with your work.
If enabled by your admins, you can set Blackout dates for yourself in these courses, and they are excluded from these calculations, so due dates don't fall on them.
- Open the Calendar.
- Select the Blackout dates button in the toolbar.
- Select Add from the My blackout dates card.
- Provide a Name, and Start and End dates.
- Select OK.
