A schedule could be processed by applications to add forthcoming events to a calendar. An [Event](https://schema.org/Event) that is associated with a [Schedule](https://schema.org/Schedule) using this property should not have [startDate](https://schema.org/startDate) or [endDate](https://schema.org/endDate) properties.
