Newton Day
January 4 · Level 6 · #1113 of 2238
Newton Day is an informal occasion to remember the scientist whose laws connected motion on Earth with the movement of planets. The date follows Isaac Newton’s birthday in the Gregorian calendar.
How it is celebrated: science enthusiasts revisit his discoveries, discuss his work and explore demonstrations involving motion or light. A prism splitting white light into a spectrum offers a particularly vivid connection to his experiments.
Newton has birthdays in two different years on paper: Christmas Day 1642 in England’s calendar at the time becomes 4 January 1643 in the Gregorian calendar.
