Calendars
For multiple dates and repeating patterns a calendar can be created, which is then applied to the
exception.
Calendars are used to group dates, which can then have exceptions applied to these dates on a
schedule. For example, a school could use a calendar to group the days that require extended
operating hours for PTA meetings.
Release function
The release function is a predetermined time in which the present schedule or the event releases
control over to the next event based on priority. Conceptually, a scheduled release is very similar
to a timed override.
For example, after the daily schedule ends at 12:00 am (midnight), the schedule releases control
over to the next event.
