The Festival of Chanukah is celebrated by lighting candles for eight nights. Actually, olive oil is preferred but candles are permissible. Chanukah is commemorating the rededication of the Temple of Jerusalem after its desecration by Antiochus of Syria.
The lights must burn for at least a half hour after the stars appear. On the first night, the first candle is set at the extreme right of the Menorah. On the second and each succeeding night, an additional light is set to the left and kindled first.
May your Chanukah candles burn brightly.
