Hm, stolen days, real Christmas.....Surely pagan festivals were originally linked to the "real" calendar of nature, the true solstice when the sun is lowest in the sky, the true events in the heavens and on Earth?
Please read any of the current crop of books on the calendar, but especially "The Calendar". The reason for the date change which brought the "British" Julian calendar in line with the Continental Gregorian calendar was not just politics, it was to bring the civic calendar back in line with the astronomical reality.
Anyone celebrating the solstice on the 6th of January was seriously off beam.
It really shouldn't matter if Christian festivals are celebrated on one date rather than another. They aren't tied to nature. But pagans should surely get their astronomy right.
