All Implemented Interfaces:
Function<Integer,LocalDate>, Predicate<Integer>, Observance
public class ChristmasEve extends AbstractObservance
Observance of Xetra/Frankfurt Stock Exchange's Christmas Eve full non-trading day (December 24, an "Erfüllungstag"/settlement day). Unlike org.holiday.calendar.observance.uk.ChristmasEveEarlyClose — which always occurs, shifting to the preceding Friday on a weekend — Xetra/FWB is simply not a trading day at all on weekends, so December 24 is omitted entirely (not shifted) in years it falls on a Saturday or Sunday. This mirrors org.holiday.calendar.observance.ca.ChristmasEveEarlyClose's suppression semantics, applied here to a FLOATING full-day holiday rather than an EARLY_CLOSE.

Verified against Deutsche Börse's official Xetra-Handelskalender (cashmarket.deutsche-boerse.com), 2023-2026.
