All Implemented Interfaces:
Function<Integer,LocalDate>, Predicate<Integer>, Observance
public class ChristmasEveEarlyClose extends AbstractObservance
Observance of the NYSE's Christmas Eve half-day close (December 24). Unlike a weekend-shifting observance, this early close does not occur at all in years where December 25 falls on a Monday, Saturday, or Sunday — it is suppressed for that year rather than moved to an adjacent date. This is why isValidYear(int) is overridden here to signal absence, rather than computeDate(int) shifting to a different day as org.holiday.calendar.observance.uk.ChristmasEveEarlyClose does.

Verified against NYSE Group's official Holiday and Early Closings Calendar press releases (ir.theice.com): December 24 is an early close only when December 25 falls Tuesday through Friday.
