Hanukkah is an eight-day Jewish holiday commemorating the rededication of the Second Temple in Jerusalem at the time of the Maccabean Revolt of the 2nd century BCE. It is celebrated by lighting a menorah, playing with a dreidel, and eating foods like jelly doughnuts. The miracle celebrated is that a small jar of oil that should have lasted only one day, lasted eight days until new oil could be made.
