Hanukkah lasts eight days. On the first day you light one candle; on the second you light two; on day 8, eight candles are lit. Another candle, the "shammes", lights the other candles; this complies with the rule that the eight candles are not to be used for illumination or other practical purposes. In all, 44 candles are lit.
