A Hanukkiah is a special type of menorah used during the Jewish festival of Hanukkah. It has nine branches: eight for each night of the holiday and one, called the shamash, used to light the others. The Hanukkiah is typically displayed in a prominent place to celebrate the miracle of the oil that lasted eight days in the Temple. During Hanukkah, a candle is lit on each night, starting with one on the first night and adding an additional candle each subsequent night. The lighting of the Hanukkiah is accompanied by blessings and songs, making it a central part of the holiday's celebrations.
