Function<Integer,LocalDate>, Predicate<Integer>, Observance
public class Deepavali extends AbstractObservance
Observance of Deepavali (Diwali), the Hindu Festival of Lights. In Singapore, Deepavali is observed on the first day of the Tamil month of Karthigai and is officially gazetted by the Singapore government each year.

Dates for 2019–2030 are sourced from official Singapore Ministry of Manpower (MOM) public holiday gazette notifications. Dates for 2031–2055 are derived from Tamil Panchang calculations (Karthigai month commencement / Karthigai Amavasai, IST/SGT) cross-referenced with Drik Panchang astronomical tables, pending official Singapore MOM public holiday gazette confirmation. All entries should be verified against MOM announcements as Singapore approaches each year.
