2.5.2.1 Special Days
There are some days on which a timeswitch program associated with another day of the
week should run instead of that for the particular day. If, for example, a holiday falls on a
Thursday and the DCS should automatically execute time reactions as if it were a
Sunday, then the user can declare the date of this holiday as a special day in the
special day register, i.e. in the above example entered as "Sunday".
The specific day defined in the special day register will be listed in brackets in the DCS
next to the actual day in every related output dated header line.

On change of date at midnight or after a new special day entry the DCS automatically
updates any declared special day for the current date.
All entered special days act only on time reactions (TRR), i.e. for a time reaction the
DCS considers the entered special day as the time reaction's 'Reason'.
2.5.3 Principle of Special Day Distribution
The PS parameters SDGP and FILE must be correctly configurated as the following
example will show.
In cases of conflict, the data of the standard calendar will be overwritten by the data of
the PS-specific calendar.
Using the CAL,SCAL;SEND function, the standard and the PS-specific special day
calendar
part
of the BPS is extracted from the DCS calendar. The OPLS=LoSD loading
function is automatically set and the distribution of this data started.
