For some tasks the daily schedules on weekdays is sufficient. However, on some specific
dates, there may be exceptions to the regular week. This can be implemented by defining
daily schedules for
exception days
. For instance, there may be a separate daily schedule for
Holidays
. The exception days are defined through a
calendar
. The calendar contains a
number of
calendar patterns
. Each calendar pattern describes a pattern of dates that define
the class of an exception, e.g.,
Holidays
.
When a calendar is defined on a system, the exception days are available in all schedules.
When a schedule wants to define daily schedules for some of the available exception days,
they need to be enabled in the schedule. See Figure 75 for an example where
Holidays

The function of the exception is simple. The daily schedule of a regular weekday is
overridden by the daily schedule of the exception, when one of the specified date patterns is
in effect (e.g., July 14
th

exception days are in use, there may be conflicts on specific dates. These conflicts are
resolved by defining
priorities
for the different exceptions. The daily schedule of the
exception with the higher priority is eventually in effect. If two exceptions with the same
