that according to every study of the bible, and other surviving documents, Jesus was born in the spring.
the "Midwinter" feast, timed for when the days are starting to get longer, has been celebrated by all peoples that actually experience major seasonal changes since the earliest communities. The Christian Church created "Christmas" to stop the people they were trying to convert to chritianity celebrating what they beleived was a pagan ritual.
[ it wasn't, it was a human celebration that was just for the joy of knowing that soon enough it would be warm again. ]
I know that most current holidays have nothing really to do with the "religous" base they are supposed to be about. :) My comment was more along the lines of pointing out the hypocritical nature of this particular holiday.
