The Cosmic Calendar is a scale in which the 13.7 billion year lifespan of our universe is mapped onto a single year. This chronological arrangement was done by famous astronomer Carl Sagan. In this mapping, the Big Bang took place on January 1st at 12 a.m., while the present moment is 12 p.m. on December 31st.

The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.

As Mike Wall from Space.com explains, while 14.5 billion is still younger than the estimated birth of the Universe, the uncertainty Bond is referring to allows for plus or minus 800 million years, which means their calculations could put the formation of Methuselah at 13.7 billion years old - just after the Big Bang, although only just.
The timeline of the Universe lists events from its creation to its ultimate final state. For a timeline of the universe from the present to its presumed conclusion, see: Timeline of the far future; Chronology of the universe; Timeline of the universe; See also.

The Cosmic Calendar To give us a better idea of the time scale involved in human evolution, it is interesting to compare the numbers involved with something a little more familiar. Here, the history of the universe has been scaled down to one year, That is, one month is equivalent to one billion year, one day to 30 million years, one hour to 1. ...
The universe has an epic story – from a tiny, hot singularity to a vast cosmos headed toward eventual silence. This timeline traces the major milestones in the universe’s life, from the Big Bang 13.8 billion years ago to a theoretical future called “heat death,” when all stars have died and no energy remains.

The Cosmic Timeline Astrophysicists have deduced the age of the Universe ... (1934-1996). Sagan was the first person to explain the history of the universe in one year-as a "Cosmic Calendar"-in his television series, Cosmos. Let us look at the calendar in a bit more detail: Cosmic Calendar (From The Dragons of Eden - Carl Sagan) Pre-December Dates.
The Cosmic Calendar is a scale in which the 13.7 billion year lifetime of the universe is mapped onto a single year. This image helps to put cosmology, evolution, and written history in context. At this scale the Big Bang took place on January 1 at midnight, and the current time is mapped to December 31 at midnight.

The cosmic timeline, from the origin of the known Universe in the Big Bang, 13.8 Billion years ago, until present day. Shown are major events based on the current standard picture. After the Big Bang, the Universe underwent “Inflation”, a period of accelerated expansion that expanded the Universe by around 60 orders of magnitude.
For one, the Universe is incredibly uniform on the largest scales, but it wasn’t clear how it had become so uniform. The proposal of a theory of “Inflation” answered many of these problems. Inflation refers to a very brief period of extremely rapid expansion in the first moments of the Universe’s existence.
By compressing the timeline of the universe into a single year, the Cosmic Calendar allows us to see how our existence fits into the grand scheme of things. In this article, we will explore the concept of the Cosmic Calendar, its significance in understanding the universe’s timeline, and how it can help us appreciate our place in the cosmos.
The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.A similar analogy used to visualize the geologic time scale and the history of life on Earth is the Geologic Calendar.
