Chanukah, meaning "dedication" in Hebrew, refers to the joyous eight-day celebration during which Jews commemorate the victory of the Macabees over the armies of Syria in 165 B.C.E. and the subsequent liberation and "re-dedication" of the Temple in Jerusalem. The modern home celebration of Chanukah centers around the lighting of the chanukiah, a special menorah for Chanukah; unique foods, latkes and jelly doughnuts; and special songs and games.
Adat Chaverim celelbrates Chanukah as a congregation in the social hall as every congregant brings their special chanakiah to light with one another. Check the Temple calendar fo details on the date/time of this special event each year.
