Calendars are shared entities that define the framework
for shifts, holidays, and so on, for organizations. A calendar can
also specify non-working time, such as weekends, holidays, and shutdowns.
Shift patterns for calendars
A shift defines working time that is not specific to a
date. You choose the working days, then you designate the start time
and end time for work.
Exceptions to the standard calendar
Information for individuals, such as vacation days, sick
leave, personal time, and overtime, is not stored on the main calendar
record.
