Events are special campaigns.

You can schedule an event, outside of a regular playback loop, to appear at a predefined time. Events can also repeat daily, weekly, monthly or yearly.

Example: Imagine that you have a New Year's Eve countdown video. You want it to start just before midnight and conclude a few minutes after midnight. You could schedule the countdown as an event. It will preempt any existing content. Once it completes, the regular loop will restart at the beginning of the interrupted slot.
