About the Jewish Calendar

The Jewish calendar (also known as the Hebrew calendar) is a lunisolar calendar used to determine the dates of Jewish holidays, Torah readings, and daily prayers. Each month begins with a new moon, and leap years add a 13th month (Adar II) seven times every 19 years to stay aligned with the solar year.

Select any city above to view a monthly calendar with:

• Shabbat candle lighting times — typically 18 minutes before sunset (40 minutes in Jerusalem)
• Havdalah times — calculated as 72 minutes after sunset (Rabbeinu Tam opinion); 8.5° (GRA) and 16.1° opinions also available on the Zmanim page
• Jewish holidays — including Yom Tov, fast days, and modern Israeli holidays
• Weekly Torah portion (Parashat HaShavua) — shown every Shabbat
• Rosh Chodesh — the beginning of each new Hebrew month
• Omer count — during the period between Pesach and Shavuot

Each city page also offers a .ics download to import candle lighting and Havdalah times into your Google Calendar, Apple Calendar, or Outlook.

Hebrew Calendar Months

The Hebrew calendar has 12 months in a regular year and 13 in a leap year (when Adar II is added). Each month begins with the new moon (Rosh Chodesh). The months do not correspond exactly to Gregorian months — they shift because the lunar year (about 354 days) is shorter than the solar year (365 days).

Leap years add a 13th month, Adar II (Adar Sheni), to keep Passover in spring as required by the Torah. Leap years occur in years 3, 6, 8, 11, 14, 17, and 19 of a 19-year cycle. In a leap year, Purim is celebrated in Adar II.
