What to know about Hanukkah and how it's celebrated around the world

Hanukkah — also spelled Chanukah or other transliterations from Hebrew — is Judaism’s “festival of lights.” On eight consecutive nightfalls, Jews gather with family and friends to light one additional candle in the menorah — a multibranched candelabra.

In Hebrew, Hanukkah means “dedication,” and the holiday marks the rededication of the Temple in Jerusalem in the 2nd century BC, after a small group of Jewish fighters liberated it from occupying foreign forces.

With the tiny supply of ritually pure oil that they found in the temple, they lit the menorah — and it stayed lit for eight days. The ritual of lighting a nightly candle, as well as the emphasis on cooking foods in oil such as potato pancakes called latkes, memorialize this miraculously long-lasting oil.
