The Hebrew calendar consists of 12 or 13 months, depending on the year! Each month has either 29 or 30 days. π
The months are: Tishrei, Cheshvan, Kislev, Tevet, Shevat, Adar, Nisan, Iyar, Sivan, Tammuz, Av, and Elul. The extra month, called Adar II, is added during leap years, making it 13 months! The calendar starts with Tishrei, when the
Jewish New Year, Rosh Hashanah, is celebrated. The Hebrew year is also different from the Gregorian calendar, which most people use today!
