What to know about Hanukkah and how it's celebrated

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.'' The holiday marks the rededication of the Temple in Jerusalem nearly 2,200 years ago 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. According to the Talmud, it miraculously remained lit for eight days. The ritual of lighting a nightly candle and the emphasis on cooking foods in oil, such as potato pancakes called latkes, memorialize this holiday.

Variations in the starting date

Hanukkah always begins on the 25th day of the Jewish month of Kislev.

But the Jewish calendar, which is based on lunar cycles, is not in sync with the commonly used Gregorian calendar. Depending on the year, Hanukkah falls at various times between late November and late December.

This year, Hanukkah starts at sundown on Sunday, Dec. 14, and lasts through Dec. 22.

Bringing light into the darkness

Jews across the religious observance spectrum — from Reform to Conservative to Orthodox — focus on the same theme of bringing light into the darkness and emphasizing that even a small, against-the-odds effort can have a transforming effect.

The Talmud, an ancient compendium of commentary and teachings on Jewish law, customs and Scripture, reflects a dispute over the order of lighting. But most people start with one candle and increase the lighting by an additional candle each night while reciting or chanting special blessings.

The candles are added from right to left, but lit from left to right on the menorah, thus always starting with the newest light. The special menorah used for Hanukkah has eight branches, with a ninth place for the candle called shamash from which all others are lit.

The tradition calls for candles with a real flame, although some also use electric ones in public displays, such as in hospitals, for safety reasons.

A menorah is lit in each household and traditionally is placed where it can be seen from the outside, such as a doorway or windowsill, to symbolize the spreading of God's light to all nations.

The lighting of menorahs in city streets and parks has become more prominent in recent years in countries around the world, including in front of public landmarks.

In addition to menorah lightings, giving to charity and social works are also part of the celebration for many, reflecting the belief that the Jewish people are called by God to help make the world better for all.
