Indicate if you want a default date to be displayed in the Date Due field on Settings > Manage Assignments.
You can select no default date, the current date, or up to five days in the future.
Example: If you selected Current Date +2, and the current date is May 20, the Date Due field on Settings > Manage Assignments will display May 22 by default. If May 22 occurs on the weekend, the Date Due field will display the date of the following Monday.
