A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. 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.
Ebenezer Burgess postulates an intercalary month was inserted every five years to anciently maintain the correspondence of the 360-day years with the true solar years (~365.24-day years). [23] For this reason, a traditional 360-day year is equivalent to a modern ~365.24-day solar or tropical year .
The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans shifted from a hunter-gatherer lifestyle to agriculture and fixed settlements.
According to the Manusmriti (c. 2nd CE), [18] one of the earliest known texts describing the yugas, the length of each yuga is 4800, 3600, 2400 and 1200 years of the gods, respectively, giving a total of 12,000 divine years to complete one cycle. For human years, they are multiplied by 360 giving 1,728,000, 1,296,000, 864,000 and 432,000 years ...

Modern human presence in Southern Africa and West Africa. [60] Appearance of mitochondrial haplogroup (mt-haplogroup) L2. 80–50 ka MIS 4, beginning of the Upper Paleolithic.
The year 1950 was chosen because it was the standard astronomical epoch at that time. [ citation needed ] It also marked [ 3 ] the publication of the first radiocarbon dates in December 1949, [ 17 ] and 1950 also antedates large-scale atmospheric testing of nuclear weapons , which altered the global ratio of carbon-14 to carbon-12 .
Say you have a 4-year-old Labrador named Comet — with the new equation, Comet's real "dog age" would be slightly older than 53. The reason for the difference is actually pretty simple.
(15) Twelve thousand of these divine years are denominated a Quadruple Age (caturyuga); of ten thousand times four hundred and thirty-two [4,320,000] solar years (18) One and seventy [71] Ages are styled here a Patriarchate (manvantara); at its end is said to be a twilight which has the number of years of a Golden Age, and which is a deluge.
