What is the purpose of creating schedules and will the schedule loop if the content gets finished?

The very purpose of creating a schedule is to demonstrate the time duration for which a content will be casted on a particular device. The schedule will be on loop if the content gets finished before the set schedule and time. It will only loop if there is more than one content and the time interval is provided incorrectly causing a time gap between both the contents. While the schedule will not be on loop if the content gets finished before the set schedule and time, due to an individual start and end time.
