Simple question.  Why does Japan celebrate the end the year on December 
31st?  I'm fully aware that the Gregorian calendar was introduced 1873.  And 
am therefore guessing that it had something to do with the Meiji era 
social-political reforms.  But if anyone has anything more detailed I'd be 
grateful.

Then I can apply myself to the great Christmas Eve love hotel conundrum.  My 
latest theory is that it's somehow related to the whole Luke 2:1-7 "no room 
for them at the inn" fiasco.  One should always book ahead in the Holy 
Land - just as Taro-san should book ahead at the Hotel Seeds.
