Holiday
Holiday header. The four holiday types with their priorities are as follows:
SPEC (special) - highest priority
DATE (month/date) - 2nd highest priority
D/WK (day of week) - 3rd highest priority
SPAN (duration) - lowest priority
To demonstrate the use of priorities, assume that Thanksgiving Break (SPEC) is pro-
grammed as a holiday schedule B. Also assume that Nov. 1st to Nov. 30th (SPAN) is
programmed as a holiday schedule A. Then on Thanksgiving Day and the Friday
after, the control will execute the events that include HOLIDAY B in their day field,
since SPEC is a higher priority than SPAN. The rest of November the control will use
events that include HOLIDAY A in their day fields. The other 11 months (assuming
no other holidays) will be controlled according to the events programmed for the
normal days (SUN - SAT).
