Happy Birthday to Sir Isaac Newton! Dec 25th
Correct for the Gregorian calendar which changed his date of birth to Jan 4, 1643 from the Julian calendar which was in use in England at the time of his birth. The Julian calendar, no longer in use in the U.S. or England, places his date of birth on December 25, 1642. It was so much of a fun fact and something of Science to look forward to on this day. Thanks for the info though ????.
