Not really true, Professor. Back when you did real science, all your astronomical calculations were relative to epochs based on either January Zero of 1950AD or 2000AD. And your Julian Date was referenced to a Biblically derived beginning of recorded history roughly 4000 years ago. Those calculations are the same today. That makes the Gregorian New Year astronomically significant. Is that still arbitrary? In a sense. But still very historically significant. Just like Sir Isaac Newton’s birthday, which you botched by celebrating on the wrong date last week, is only historically significant. Nice try, though. Dork.
