Enum Constant Detail

BIRTHDAY

public static final HebrewAnniversary BIRTHDAY

Marks the annual birthday in hebrew calendar.

The underlying rule takes care of possible leap days (relevant for HESHVAN and KISLEV) and leap months. Example for determining the 13th birthday of a boy born in AM-5776-ADAR_I-30 (bar mitzvah):

     HebrewCalendar birth = HebrewCalendar.of(5776, HebrewMonth.ADAR_I, 30);
     assertThat(
          birth.get(HebrewAnniversary.BIRTHDAY.inHebrewYear(birth.getYear() + 13)),
          is(HebrewCalendar.of(5789, HebrewMonth.NISAN, 1)));
 

Note: The predefined method HebrewCalendar.barMitzvah() is simpler to use for this special purpose.

YAHRZEIT

public static final HebrewAnniversary YAHRZEIT

Marks the annual death day of a near relative in hebrew calendar.

The rules follows the book "Calendrical Calculations" by Dershowitz/Reingold. Some Jewish communities might deviate from these rules, however.
