Function<Integer,LocalDate>, Predicate<Integer>, Observance
public class VesakDay extends AbstractObservance
Observance of Vesak Day (also known as Buddha's Birthday), commemorating the birth, enlightenment, and death of Gautama Buddha. In Singapore, Vesak Day falls on the full moon of the fourth month of the Chinese lunisolar calendar, observed as a public holiday on the date officially gazetted by the Singapore government.

Dates for 2019–2030 are sourced from official Singapore Ministry of Manpower (MOM) public holiday gazette notifications. Dates for 2031–2055 are pre-computed from the Hong Kong Observatory Gregorian-Lunar Calendar Conversion Tables (day 15 of Chinese lunisolar month 4 in SGT), pending official MOM gazette confirmation. All entries should be verified against MOM announcements as Singapore approaches each year.
