Last night marked the first night of Chanukah, the Festival of Lights.
Chanukah is also spelled Hanukkah. It's Hebrew. So there's no one correct spelling in English. I choose the "Ch" to remind us that the correct pronunciation of the holiday begins with the "ch" found in "Lach Ness Monster" and not the "h" in "happy."
The candle in the middle is the Shammash, or helper candle. You light that one first and then light all the other candles with it, but it doesn't "count." (Candles, like people, need helpers to stand by them and to re-light their flames when they go out. The Shammash is the candle dedicated to public service.)
Every night of the eight nights of Chanukah, Jews will light one more candle until we have filled the Menorah with 9 candles (8 plus the Shammash.)
