At sundown on December 10th, 2020, Jewish families worldwide will commemorate the first night of Hanukkah, by lighting a candle on a hanukkiah or menorah. Often called the Festival of Lights, Hanukkah, which means "dedication" in Hebrew, is an eight-day celebration observed annually on the 25th day of Kislev — the Jewish calendar's ninth month. Though the exact date varies, the holiday always occurs sometime between late November and December.
