Carl Sagan's Cosmic Calendar, in which the entire 13.75 billion-year history of the universe is scaled down to a single year. At this scale, the Earth formed in August, life arose in September, and the first land plants appeared in mid-December. Apes did not appear until the very last day of the year. The first humans show up in the last six minutes and civilization in the final 30 seconds.
