The hanukkiah
A lamp with nine branches: eight for the days, and a ninth, the shamash (“helper”), used to light the others. It is placed where it can be seen.

Customs
Hanukkah's customs weave together light, gratitude and family joy. Above all: kindle the lights and retell the miracle to the next generation.
A lamp with nine branches: eight for the days, and a ninth, the shamash (“helper”), used to light the others. It is placed where it can be seen.
A candle is added left to right each night, but lit right to left, beginning with the newest. Blessings are recited before lighting.
A four-sided spinning top bearing the letters נ, ג, ה, ש — “Nes Gadol Haya Sham” (“A great miracle happened there”). A beloved children's game.
Coins given to children as “Hanukkah gelt”; over time, chocolate coins wrapped in gold foil became popular too.
An “Al HaNisim” passage of thanks for the miracles is added to prayers and the grace after meals; the festive Hallel is also recited.
The hanukkiah is placed so passers-by can see its lights — the public proclamation of the miracle.
The order
On the first night, a single candle is placed at the right and lit with the shamash. Each following night one more is added to the left, and lighting always begins with the newest, left-most candle, moving rightward.
The candles are lit after sunset (before sunset on the eve of Shabbat). While they burn — about half an hour — it is customary not to work, to sing “Maoz Tzur” and to be together as a family.
