Jewish calendar

The Jewish calendar is a lunisolar calendar, meaning it is based on both the moon's phases and the sun's cycles. It has 12 months in a normal year and 13 months in a leap year, which occurs seven times in a 19-year cycle. Months alternate between 29 and 30 days, aligning holidays with the seasons. Major holidays include Rosh Hashanah (New Year), Yom Kippur (Day of Atonement), and Passover (celebrating the Exodus). The Jewish year typically begins in September or October, with the year numbering based on the traditional date of Creation.
