Hanukkah

It started yesterday!
"Hanukkah", from the Hebrew word for "dedication" or "consecration", also known as the Festival of Lights, is an eight-day Jewish holiday commemorating the rededication of the Holy Temple in Jerusalem at the time of the Maccabean Revolt of the 2nd century BCE.

I feel that I need to know more things about other cultures and religions...
