In hmolscience, dating system refers to a method for chronologically ordering events in the framework of an epoch or an instant in time chosen as the origin of a particular era.
The current Western hemisphere dating system—the epoch of the anno Domini calendar era—is religio-mythology based, namely epoch of the Christian era, in which the instant in time chosen as the origin is the birth of the fictional character Jesus Christ, a semi-anthropomorphized syncretism rewrite of the Egyptian god “Osiris anointed”, the literal etymological translation of the former, of Anunian theology. Scientists and other discerning thinkers, subsequently, often have tended to take issues with this incongruent mode of dating; one example of which is shown below, the statement dated with three alternative dating system modes:
“I have dictated thirty pages on the world’s religions; and I have read the Bible. My own mind is made up. I do not think that Jesus Christ ever existed.”— Napoleon Bonaparte (1817 AD) (367 PE) (175 ME)

See main: Paine dating systemIn 1802, Thomas Paine, in his letters to Elihu Palmer, was dating them as follows:
“Paris, February 21st, 1802, since the fable of Christ”
“Ctesibius had been responsible, about -230, for a simple and fundamental machine, the piston air-pump, known from the descriptions of later mechanicians. This simplest of pumps entered upon a new incarnation in the +17th century, when the virtuosi began to explore with excitement the properties of vacuous spaces, for what had been invented originally as a bellows for pumping air into something now found fresh employment as the ‘air-pump’ for getting as much air as possible out of it.”— Joseph Needham (1987), Science and Civilization in China: Volume 5 (pg. 555) 
“Excellent point. Personally, I prefer the Copernican dating system in which we count the number of years before and after the year of the publication of the De revolutionibus orbium coelestium (of course with the inclusion of a year 0, being the year of publication). In which case we live in the year 473 AP. Sadly not a lot of people know about this dating system so I am forced to use the BCE, CE system on occasion.”— AlwaysUnite (2016), Reddit message to Libb Thims, Oct 4
“1642 [the year of Newton’s birth] is the Christmas of the modern age.”— Johann Goethe (c.1810), Publication

“All before Goethe are ancients, and all who have read him are modern.”— Ralph Emerson (1852), commentary on Margaret Fuller 
“In the era BC (before cybernetics) it [Elements of Physical Biology] was an important source of education and encouragement for few souls who had gleam in their eyes about the prospective mathematization of the social sciences. It had a substantial influence on Henry Schultz and Paul Samuelson, and, I am sure, many others besides myself. As a matter of fact, most of the ideas of [Norbert] Wiener emphasizes—for example, the relation of entropy to organizational behavior—can be found in Lotka, and I have felt some annoyance at the lack of recognition of the latter’s contributions.”
“Written in the land of the living; on the right bank of the Adige, in Verona, in the year of that god whom you never knew the 1345th.”— Petrarch (1345), signoff to a letter; compare: Goethean calendar 
“When referencing dates based on the approximate birth of Jesus, give appropriate credit for the basis of the date (B.C. or A.D.). "BCE" and "CE" are unacceptable substitutes because they deny the historical basis—i.e. they are anti-Christian. See CE.”— Benjamin S. (2006), Conservapedia, Commandments (Ѻ)
“10 Jul 2014? Nah. The Christian Calendar is disgustingly deleterious.”— NikolaTesla (2014), post #58 in the Beg-Thims discussion
