This reop contains a little code (in some languages) for the calculation of the hebrew calendar i made for learning purposes. The code is not optimized and may contain errors.

The code is based on the book Calendrical Calculations by Edward M. Reingold and Nachum Dershowitz.

For any hebrew year the code can calculate the following:

• the cycles and remainder of a given year in the 19-year cycle.
• the number of months since the beginning of the cycle.
• the number of months since the Molad Baharad (2 days, 5 hours, and 204 parts)
• the Molad Tishri for the given year
• the weekday of Rosh Hashanah for the given year
• the weekday of the first day of Pesach for the given year
• the type of the year for a given year (חסרה, מלאה, שלמה)
• the number of days in the year
