All Implemented Interfaces:

Function<Integer,LocalDate>, Predicate<Integer>, Observance

public class QingmingFestival
extends AbstractObservance

Observance of Qingming Festival (清明, Tomb Sweeping Day), which falls on the solar term at ecliptic longitude 15° — the 5th of the 24 Chinese solar terms. It occurs on 4 or 5 April in the Gregorian calendar.

The date is computed via Time4J's ChineseCalendar.ofQingMing(year), which applies the SolarTerm.MINOR_03_QINGMING_015.sinceLichun() operator using precise astronomical solar-longitude calculations.
