To celebrate the ancient miracle of the oil burning a candle for eight nights, Jews celebrating Hanukkah light a candleholder called a menorah for eight nights. The menorah holds nine candles—one for each night plus a candle called the shamash used to light the other candles. On the first night, one candle is added to the menorah and lit. On the second night, another candle is added and lit. The adding and lighting of candles continues for eight nights. During these moments, people recite special blessings and prayers, sing songs, and exchange gifts to celebrate the miracle in the temple more than 2,000 years ago. https://kids.nationalgeographic.com/
