The Cosmic Calendar is a method used to visualize and better understand the timeline of the universe. Midnight, January 1st, is when the Big Bang occurred, and December 31st, 23:59:59, is modern time. On the Cosmic Calendar, the early development of the universe ranged from January 1st to September 6th and the first known biotic life on Earth formed on September 14th. Dinosaurs lasted from December 25th to December 30th, 6:24. What is very interesting is the existence of primitive humans, starting on December 31st, 22:24, with the development of agriculture on 23:59:32. From this point on, from the end of the Ice Age to the start of Modern History, our history has lasted for less than 30 seconds on the Cosmic Calendar. Dinosaurs roamed the Earth for 5 days on the Cosmic Calendar, significantly more time compared to our short 7 seconds since the Iron Age. Despite the short while we have existed, we have discovered, learned, and created so much that has impacted Earth and the species on it in significant ways, for better or for worse.
