375 years ago on this day, Isaac Newton was born. We don’t know whether the apple that inspired him to his theory of gravitation was green or red, so I guess the admins play it safe.

Isn't Newton's birthday January 4th, but was December 25th in their calendar back in the day? Or is it the other way around?

You are correct. He was born December 25th, 1642 as per the Julian calendar and January 4th, 1643 as per the Gregorian calendar that almost everyone uses today.
