According to Carl Sagan’s Cosmic Calendar visualization – a method to visualize the vast history of the universe in which its 13.8 billion year lifetime is condensed down into a single year – the Big Bang took place at the beginning of January 1 at midnight, and the current moment maps onto the end of December 31 at midnight. Sagan goes on to extend the comparison in terms of surface area, explaining that if the Cosmic Calendar is scaled to the size of a football field, then “all of human history would occupy an area the size of [his] hand”.
