It’s best to choose a start date so that there will be no interruptions or school breaks during the 22-day course. For example, if spring break begins on April 15th, and you want to make sure students can finish everything by that date, you would set your launch date to March 25th.
If you need to change the start date after you created your class, you can do so from the Manage Class page. However, we do not recommend changing the start date after students have begun completing the course. While it is possible to change the start date after students have begun the course, it may create some unanticipated technical issues.
