I've always wondered if Chanukah would still be as commonly celebrated among Jews if it occured during any other time of the year. I suspect that were it not for it occuring right before Christmas, it would be about as commonly practiced as Sukkot.
We celebrate Purim plenty and it is nowhere in the proximity of Halloween.
Oh, and for people wondering about the spelling, here it is in Hebrew: חֲנֻכָּה
Because they really were all wondering...
I know that we celebrate Purim, but Purim hasn't become commercialized to the extent that Channukah has.
