The document describes how to set the submission period and results release date for Turnitin assignments in Moodle. After selecting the Turnitin assignment, the start, due, and post dates are displayed. The start date is when students can first submit papers. The due date is the last day students can submit unless late submissions are allowed. The post date is when students can view grades, and must be on or after the due date. Users can click edit to change the dates by selecting new hours, minutes, dates, months, and years. Both the due date and post date need to be changed together. After completing the changes, the system returns to the summary page with the revised dates.
