<holidayfyi-glossary slug="hebrew-calendar"></holidayfyi-glossary>A lunisolar calendar used for Jewish religious observances, combining lunar months with a solar correction cycle. An extra month (Adar II) is added in 7 of every 19 years to keep festivals aligned with their agricultural seasons. Jewish holidays like Rosh Hashanah, Yom Kippur, and Passover are determined by this calendar.
