Cosmic calendar is one of the ways of explaining and understanding history of
universe, whole universe’s age in this calendar (13.7 billion )years is
calculated as a year ,a day is like 37.8 million years , a minute is equivalent
to 1.58 million years and a second is 438 years. According to this calendar
(BIG BANG) event happened at (1th) January’s midnight and the current time is 31th
December’s mid night .
This concept was
popularized by Carl Sagan in his book “The Dragons of Eden” and on his television series Cosmos. In
the 2014 sequel series, Cosmos: A( Space
time Odyssey), host ” Neil deGrasse Tyson” presents the same concept of a Cosmic Calendar, but
using the revised age of the Universe of 13.8 billion years as an improvement
on Sagan's 1980 figure of 15 billion years. 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(1) an area the size of [his] hand", here are some event according to this calendar in past:
