About the Jewish Calendar

Calendar System

The Jewish calendar is a lunisolar calendar that combines lunar months with solar years. It consists of 12 or 13 months, with leap years occurring 7 times in a 19-year cycle.

Each month begins with the new moon, and months alternate between 29 and 30 days. The calendar year can have 353, 354, 355, 383, 384, or 385 days.

Hebrew Months

The Jewish year begins with Tishrei (September/October) and includes months like Cheshvan, Kislev, Tevet, Shevat, Adar, Nisan, Iyyar, Sivan, Tammuz, Av, and Elul.

In leap years, an additional month called Adar I is added before the regular Adar (which becomes Adar II).

Date Format

Hebrew dates are written right-to-left with the day of the month, followed by the month name, then the Hebrew year. Numerical values use Hebrew letters.

The Hebrew calendar epoch begins at the creation of the world, calculated as 3761 BCE in the Gregorian calendar.

Religious Significance

The Hebrew calendar determines the dates of Jewish holidays, festivals, and religious observances. It’s essential for calculating Shabbat times, holiday dates, and lifecycle events.

Major holidays include Rosh Hashanah, Yom Kippur, Sukkot, Hanukkah, Purim, and Passover, each with specific calendar calculations.
