Dating system

In chronology, dating system (TR:35) (LH:4) (TL:39) is a method of time-keeping with respect to the counting of the annual rotations of the earth about the sun, generally based on an agreed “zero year”, from which years forward and backwards are counted; or with respect to categorizations of epochs, eras, or events, such as geological periods or extinction periods, or cosmological events, e.g. big bang dating system.

Overview

Historically, many systems have been employed to date or number years of revolution of the earth around the sun.

BC/AC

See main: Dionysian calendar

The current dating system, employed in scientific writing, is the myth-based Christ birth dating system, invented in 525AD (1260AUC) by Dionysius Exiguus, Roman monk, during the reign of Charlemagne (742-814), introduced the BC/AD dating system, usurped the previous AUC dating system, with a “from Rome construction” dating, according to him to have begun at the approximate mid-point (6.5 BC) of the reign of Caesar Augustus, from 27 BC-14 AD, but overtly themed it as a “birth of Christ” dating system, to align with the then-established Christianity form of the state religion, but passed along to us with no exact details as to how the "zero year" was determined.

Needham notation

In 1BE [+1954], Joseph Needham, the editor of the 28-volume Science and Civilization in China, completed 49AE [+2004][1], employed a "+/- notation" scheme, in place of BC/AD.

On 22 Oct 66AE [+2021], Hmolpedia, amid the elementum calendar upgrade, began water-testing the Needham notation system, to use in parallel with the BE/AE notation for dates paragraphs. The following shows the Needham notation for dates, below left, with the new Hmolpedia dating system, showing Needham notation and elementum calendar dates combined, for easy of recognition:

Needham Hmolpedia
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)[2]
Ctesibius had been responsible, about 2185 BE [-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 354-255BE [+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 (32AE) [+1987], Science and Civilization in China: Volume 5 (pg. 555)[2]

Here, the +/- method is employed, albeit with Dionysian years shown in square brackets, e.g. "230BC" (Dionysian) to "-230" (Needham) to "2185 BE [-230]" (Hmolpedia) year notation upgrade.

A general rule of thumb, with respect to readability, is that if the elementum date is four digits (or more) leave a space in between the date the year acronym, e.g. 2185 BE (better readability) vs 2185BE (less readable), and for three digits (or less) don't leave a space, e.g. 300BE, 32AE, or 1AE, are all readable.

BE/AE

See main: Thimsian calendar

The new scientific dating system, employed in Hmolpedia, is the "atoms first seen" (BE/AE) dating system, invented in 65 AE (2020AD) by Libb Thims , which dates the zero year to the year when atoms were first seen by the human eye, which occurred in the year 1955AD or 0AE.

Other systems

Petrarch

In 1345, Petrarch was dating his letters as follows: “1345 of the year of the god who you never knew”.

Paine

In 1802, Thomas Paine, in his Painean calendar, was dating his letters as follows: "February 21st, 1802, since the fable of Christ".

Holocene calendar

In 1993, Cesare Emiliani, a geological micropaleontologist, proposed the “holocene calendar”, the zero year defined as the “birth of Jesus” minus 10,000 years. Hence, to exemplify, with comparison to the elementum calendar, the year he proposed the new calendar system would be defined as follows:

Dionysian Holocene Elementum
1993 ACM 11933 HE 38 AE

Emiliani introduced this calendar to eliminate the BC–AD chronology gap caused by the lack of a year 0.[3]
