The earth is in the same arbitrary spot of its orbit around the sun, a random handful of days after the winter solstice. So what do we do? We toss out paper calendars that most of us don't use anymore and replace them with new ones.
Now I am all for a good party, whatever the reason. But I swear that has to be the lamest, most arbitrary, and most nonsensical reason I've ever heard for a society to celebrate on a given day. So it probably goes without saying I'll probably be celebrating New Years eve pinching a loaf.
Otherwise, it's just like any other day of the year...
