Activity dates

Activity dates is a Moodle admin tool that bulk-schedules activity open and close dates across a course on a timed-session basis. A teacher picks an activity type (quizzes, choices, feedback, SCORM, or any module with timeopen/timeclose columns), sets a schedule window, a session length in days, and how many activities belong to each session. The tool splits the course's activities into sessions in course order and writes each session's window straight into every selected activity's own open and close dates, so students get native "Opens/Closes" information and calendar events, with no availability restrictions involved. Unselected activities can optionally be hidden or have their dates reset.
