The Difference Between Christmas Day and Christmas Day

The Vatican came up with this system to adjust the calendar. Pope Gregory the 13th was so powerful. He declared the 5th of October followed by the 15th of October through away 10 days. And so they literally had wars about it and that's how we ended up with this discrepancy where Newton, Isaac Newton's mom thought it was Christmas Day but everybody on the card thought it was the 4th of January.
