All Implemented Interfaces:
Cloneable, Comparable<JewishDate>
public class JewishCalendar extends JewishDate
The JewishCalendar extends the JewishDate class and adds calendar methods. This open source Java code was originally ported by Avrom Finkelstien from his C++ code. It was refactored to fit the KosherJava Zmanim API with simplification of the code, enhancements and some bug fixing. The class allows setting whether the holiday and parsha scheme follows the Israel scheme or outside Israel scheme. The default is the outside Israel scheme. The parsha code was ported by Y. Paritcher from his libzmanim code.

The notation used below is D = days, H = hours and C = chalakim. Molad BaHaRad was 2D,5H,204C or 5H,204C from the start of Rosh Hashana year 1. For molad Nissan add 177D, 4H and 438C (6 * 29D, 12H and 793C), or 177D,9H,642C after Rosh Hashana year 1. Tekufas Nissan was 7D, 9H and 642C before molad Nissan according to the Rambam, or 170D, 0H and 0C after Rosh Hashana year 1. Tekufas Tishrei was 182D and 3H (365.25 / 2) before tekufas Nissan, or 12D and 15H before Rosh Hashana of year 1. Outside of Israel we start reciting Tal Umatar in Birkas Hashanim from 60 days after tekufas Tishrei. The 60 days include the day of the tekufah and the day we start reciting Tal Umatar. 60 days from the tekufah == 47D and 9H from Rosh Hashana year 1.
