The Cosmic Calendar casts the 13.7 billion year lifetime of the universe into a single calendar year, and was popularized by Carl Sagan on his television series Cosmos, and in his book The Dragons of Eden.
A few mind-blowing bits of perspective:
- The Milky Way does not form until May.
- Our Solar System arrives in August.
- First life appears on Earth in September.
- Dinosaurs are extinct on December 30.
- Modern humans evolve on December 31 at approximately 11:54pm.
- Recorded history begins in the final 15 seconds of the year.
- Columbus arrives in America in the last second of the year.
