Hanukkah (spelled Chanukah in Yiddish) is the Jewish Festival of Light. It begins at sundown December 16, 2014. This eight-day feast fluctuates on the western Gregorian calendar. It always lands between late November to early December on the Gregorian calendar. On the Hebrew lunar calendar it's always the 25th of Kislev.
Hanukkah is not the Jewish Christmas. The two holidays share nothing except calendar proximity on the calendar. Hanukkah celebrates the Miracle of the Maccabees, when the temple lights did not burn out for eight days. The festival involves lighting the menorah, feasting, dreidel games and other activities.
