The Cosmic Calendar is the life of the universe condensed into a calendar year. It begins on January 1st at midnight and ends on December 31st just before midnight. The noteworthy time on this calendar is 8pm on December 1st: the start of human life. The universe is approximately 14 billion years old, so humans have only been alive for an extremely small portion of this time. Neil deGrasse Tyson hosted a documentary, that describes the life of the universe in detail and I highly recommend that you watch the documentary if you want to learn more about the Cosmic Calendar!

Good Post! The cosmic calendar really places our sense of time within context of the universes existence. Have you taken a look at theories for the possible end states of our universe? It would be the end of the cosmic “year”.

I have not actually. But thank you for the insight! I’ll start looking into that for future posts.
