The Jewish religion has its own holidays and traditions, so they don't celebrate Christmas. Their most important holiday is Hanukkah, which is a celebration of the rededication of the Jewish temple in Jerusalem after it was reclaimed from the Greeks. It's also known as the Festival of Lights, because it involves lighting the candles on the menorah, which is a special candelabra with eight branches and one central candle. Hanukkah is a time for family and friends to gather and enjoy traditional foods, play games, and exchange gifts.
