I know, the title of this task sounds like the signature of a gothic personal ad. But it's for real!

I'm writing the novel Son of Man about a young man who grows up thinking he may be Jesus. The climax of the story (that leads a "crucifixion") is a demonstration that should take place in 2004 in mid to late November or early December. The date should have some occult significance, preferably as being the day when the world of the evil dead is close to our world and that kind of stuff.

Now, the Celtic festival of Samhain has this potential. Nowadays it's usually celebrated at Halloween (October 31st), but apparently the Real Halloween according to ancient Celtic lunar calendar might be somewhere between 20th October and 25th November... If I understand correctly all the Wiccan websites I've browsed through.

But is there anyone here with Google-Fu or Pagan Lore powerful enough to tell me when Lunar Samhain was in 2004?

Or if you know of other important occult dates from thereabouts, please inform me!
