A schedule defines a repeating time period used to describe a regularly
occurring SchemaEvent. At a minimum a schedule will specify
SchemarepeatFrequency which describes the interval between occurrences
of the event. Additional information can be provided to specify the
schedule more precisely. This includes identifying the day(s) of the week
or month when the recurring event will take place, in addition to its
start and end time. Schedules may also have start and end dates to
indicate when they are active, e.g. to define a limited calendar of
events.
