No, and no again. Hanukkah is a totally different holiday and has nothing to do with Christmas other than a miracle that had happened. Hanukkah follows the Hebrew Calendar so the days may vary and yes, there are times when it falls near or even on Christmas.
I see many places in Second Life that have a Christmas Tree and a Menorah, which is really not necessary. You do not have to be politically correct by putting up decorations for both holidays. Unless you are Jewish, just skip the decor.
Did you know that latkes were not really part of Hanukkah? the Maccabees did not eat latkes; they only celebrated the miracle of the oil burning for eight days. Now, I love latkes (potato pancakes) all year round and I do not wait until Hanukkah. And, yes don't forget the jelly-filled donuts that are called sufganiyot.
Somebody asked me why are there no Hanukkah parties in Second Life? Hanukkah is basically celebrated at home, not at a party. You celebrate the festival of lights and the dedication of the tradition behind Hanukkah.
So, if you hear of a Hanukkah party it is probably a private event for Jews and their guest (which could be any religion). Feel honored if you are invited to a party like that.
There you go a little history about this holiday and whatever you celebrate remember the meaning behind it and why it is celebrated. Not because there are gifts or food involved which of course are great, but because it is the dedication we put into it.
Happy Hanukkah!!!
