I was walking through Harvard Yard at about 10:50 PM last night when a girl standing at a window on the fourth floor of Thayer called out to me. "Hey," she said. "When does Hannukah start this year?" Obviously, I was not able to answer her question.

When I was a Harvard freshman, I generally used more authoritative sources of research than random strangers walking through the Yard. Still, random freshman, in case you are reading this, Hanukkah begins at sunset on Friday, December 15.
