It’s often said that Isaac Newton was born on December 25, 1642. That’s true in the fact that Newton’s birth is indicated as that date in historical records, but it is more accurate to note that Newton was born on January 4, 1643. That’s is birthday in our modern Gregorian calendar. At the time of Newton’s birth, England used the older Julian calendar, hence the difference in dates.
