The Cosmic Calendar

The Cosmic Calendar is a way to visualize the universe's 13.8-billion-year history condensed into a single year. Imagine compressing everything from the Big Bang to today into one calendar year, where January 1 represents the universe's birth. Events like the formation of our galaxy occur in March, while Earth's formation appears in September. Human history accounts for only the last few seconds of December 31, illustrating how recent our existence is in cosmic terms. This analogy helps us grasp the vast scale of cosmic time, highlighting the universe's immense age and our relatively brief place within it.
