Actually, it's far worse than that. I was reading up on the adoption
rate of the gregorian calendar, and because of delays in its adoption by
various folks over the centuries since it was invented (and the fact
that some religions STILL don't recognize it) there are many dates that
are recorded differently throughout history since it was created.
I read up a bit on it at http://en.wikipedia.org/wiki/Gregorian_calendar
and it's enough to make your head spin... The trivia section near the
bottom is particularly interesting.
