Definition
Schedule. A collection of events or things that will be done and the dates and/or times when they will be done
The overall period covers the entire DatePeriod of the Schedule, from the earliest Date to the final Date of the Schedule.
Schedules may be ad hoc, essentially a list of dates and events without any consistency in the durations between events, regular, in which case there is a consistently recurring interval between events, or a combination of the two.
