What's the difference between the era of the Yellow Emperor and AD?

To put it simply, one is based on the birth of the Yellow Emperor and the other is based on the birth of Jesus in the West.

See below for details.

With regard to the chronology of the Yellow Emperor, it is generally said that the first year began in the year when Xuanyuan, the ancestor of Chinese culture, came to power after unifying the Central Plains (that is, "Huaxia") (some people call it "the year when the Yellow Emperor was born"). The earliest formulation of the Chronicle of the Yellow Emperor began with the hand of Liu Zhi, a master of Confucian classics in the late Qing Dynasty. 1903 published the article "Chronology of the Yellow Emperor", saying that "the Yellow Emperor is also the Yellow Emperor of the Han nationality and can feel the Han nationality". Therefore, "if China people want to follow the aspiration of the Yellow Emperor, they should choose their goodness and follow it, and learn from Japan with the chronology of Emperor Jimmu and the meaning of the Yellow Emperor. [1] 1905, Song determined that the first year of the Yellow Emperor's accession to the throne was Guihai, which was 4603 years different from 1905. [2] 19 12 At the beginning of the year, Sun Yat-sen became the interim president and changed the solar calendar. " November 13th, the year of the Yellow Emperor, is the first day of the Republic of China. "[3] Soon after, The Chronicle of the Yellow Emperor disappeared in the history of China. The chronology of branches and branches consists of ten branches such as "A, B, C and D" and twelve branches such as "Zi, Ugly, Yin and Mao", which are used to divide and establish the codes of branches and branches corresponding to the calendar year, month, day and the 24 solar terms of the Yellow Emperor. Among them, the heavenly stems have a period of ten years, and the earthly branches have a period of twelve years. The chronology of trunks and branches begins in Jiazi and ends in Guihai, with a period of 60 years. According to the current general theory, the first year of the Yellow Emperor was either Jiazi [4] or Guihai, which was 2698 years earlier than the first year of AD. The author agrees that the first year of Huangdi is the first year of Jiazi, which is more in line with the traditional chronology of cadres and branches in China. From this calculation, the first year of A.D. is the year of Huangdi in 2698, and the corresponding dry year is Xinyou. A.D. 2008 is the year of Huangdi in 4705, and the corresponding dry year is Wuzi.

Huangdi AD 4705-AD 2008

Huangdi Era 4706 ←→ AD 2009 The following are two formulas for calculating Huangdi Era. Because there is no "0 year" between "BC 1" and "AD 1", the calculation of BC is different from that after AD: the year of the Yellow Emperor = 2698 BC.

In addition, I suggest that the symbol capital letter "H" be used to represent the era of the Yellow Emperor, and the capital letter "S" be used to represent the era before the Yellow Emperor. Why? Because "H" represents both "Yellow" of "Yellow Emperor" and "Hua" of "Huaxia", while "S" represents the era of "myths and legends". Under normal circumstances, the "H" in the era of the Yellow Emperor can be omitted. Finally, teach me how to quickly know the year of a certain year. 1 to 10 indicates the heavenly stems "A, B, D, E, G, G, Xin," and 1 to 12 indicates the earthly branches "Zi Chou Mao Yinchen has applied for the World Heritage at noon". Then divide the year by 10 to get the remainder, and the remainder corresponds to the corresponding heavenly stems; Divide the year by 12, and the remainder will branch accordingly. For example, in the year of Huangdi in 4705, when 4705 is divided by 10, the remainder is 5, corresponding to "e", then 4705 is divided by 12, and the remainder is 1, corresponding to "zi", then the year of Huangdi in 4705 is the year of Wuzi.

A. D. is the abbreviation of "Gregorian calendar era", which is an international calendar system. The legendary birth year of Jesus Christ is the first year of Gregorian calendar (equivalent to the first year of Emperor Ping of the Western Han Dynasty in China). AD is often represented by a.d. (Latin abbreviation of Anno Domini, meaning "the year when the Lord was born"), while BC is represented by b.c. (abbreviation before Christ, meaning "before Christ"). This chronological system began to be adopted by European countries. China adopted the Gregorian calendar month and day (19 12) one year after the Revolution of 1911, but at the same time adopted the year of the Republic of China. The calendar year of People's Republic of China (PRC) adopts the calendar year system of most countries in the world, which was decided at the first plenary session of China People's Political Consultative Conference in September 1949. At the meeting, everyone agreed to adopt the common calendar system in most countries in the modern world, that is, adopt AD as the calendar year of new China. On September 27th, the second of the four resolutions adopted at the first plenary session of the China People's Political Consultative Conference was: "The year number of People's Republic of China (PRC) adopts AD". There are many dating methods in the world, but at present the most commonly used method in the world is the AD dating method. In addition, there are chronologies of cadres and branches, astronomical chronologies, historical chronologies, and chronologies of emperors' titles. In addition, there are Islamic times, Buddhist times, Jewish times, Greek times, Japanese times and so on. In China, as early as 2000 BC, it had its own calendar. For a long period of history, China adopted the "era method of cadres and branches", that is, the ten-day cadres and the twelve-day branches were combined into one, and every 60 years was a cycle.
