The Jewish calendar is a lunisolar calendar, meaning it synchronizes both lunar months and solar years. This calendar is used to determine the dates of Jewish holidays, and it differs from the Gregorian calendar. As a result, Jewish holidays fall on different Gregorian dates each year. The Jewish calendar consists of 12 months in a common year and 13 months in a leap year. The leap year helps to keep the lunar and solar cycles aligned.
