The Cosmic Calendar

Imagine if the entire history of everything was reduced to a single year. Each day of that year would represent millions and millions of years of real human life. This curious idea was made famous by a brilliant scientist named Carl Sagan.

In the Cosmic Calendar, New Year's Day would be the day the Big Bang occurred, about 13.8 billion years ago. As the calendar progresses, we see galaxies form, stars shine, and planets are born. Almost reaching the end, we meet the first dinosaurs, birds, and flowers. Also, we see the asteroid that almost wiped out all life on Earth! On the last day of the year, we see the appearance of our species, and in the last seconds, all our great adventures, ideas, and dreams come true...

This way of looking at the universe helps us understand how long the universe has existed and how little we humans have been here. Also, how special our time here is, how much we should appreciate it, be grateful for it, and make the most of it.
