Yellow Emperor - Traditional Dates

Traditional Dates

Although the traditional Chinese calendar did not mark years continuously, some Han-dynasty astronomers tried to determine the years of the life and reign of the Yellow Emperor. In 78 BC, under the reign of Emperor Zhao, an official called Zhang Shouwang (張壽望) calculated that 6,000 years had passed since the time of Huangdi; the court refused his proposal for reform, countering that only 3,629 years had elapsed. In the proleptic Julian calendar, the court's calculations would have placed the Yellow Emperor in the late 38th century BC rather than in the 27th century BC that is conventional nowadays.

During their missions in China in the seventeenth century, the Jesuits tried to determine what year should be considered the epoch of the Chinese calendar. In his Sinicae historiae decas prima (first published in Munich in 1658), Martino Martini (1614–1661) dated the royal ascension of Huangdi to 2697 BC, but started the Chinese calendar with the reign of Fuxi, which he claimed started in 2952 BC. Philippe Couplet's (1623–1693) "Chronological table of Chinese monarchs" (Tabula chronologica monarchiae sinicae; 1686) also gave the same date for the Yellow Emperor. The Jesuits' dates provoked great interest in Europe, where they were used for comparisons with Biblical chronology. Modern Chinese chronology has generally accepted Martini's dates, except that it usually places the reign of Huangdi in 2698 BC (see next paragraph) and omits Huangdi's predecessors Fuxi and Shennong, who are considered "too legendary to include."

Starting in 1903, radical publications started using the projected date of birth of the Yellow Emperor as the first year of the Chinese calendar. Different newspapers and magazines proposed different dates. Jiangsu, for example counted 1905 as year 4396 (making 2491 BC the first year of the Chinese calendar), whereas the Minbao (the organ of the Tongmenghui) reckoned 1905 as 4603 (first year: 2698 BC). Liu Shipei (劉師培; 1884–1919) claimed that the 1900 international expedition sent by eight foreign powers to suppress the Boxer Uprising entered Beijing in the 4611th year of the Yellow Emperor. Liu's calendar started with the birth of the Yellow Emperor, which was reckoned to be 2711 BC. When Sun Yat-sen declared the foundation of the Republic of China on 2 January 1912, he decreed that this was the 12th day of the 11th month of year 4609 (epoch: 2698 BC), but that the state would now be using the solar calendar and count 1912 as the first year of the Republic. Chronological tables published in the 1938 edition of the Cihai (辭海) dictionary followed Sun Yat-sen in using 2698 as the year of Huangdi's accession; this chronology is now "widely reproduced, with little variation."

Helmer Aslaksen, a mathematician who teaches at the National University of Singapore and specializes in the Chinese calendar, explains that those who use 2698 BC as a first year probably do so because they want to have "a year 0 as the starting point", or because "they assume that the Yellow Emperor started his year with the Winter solstice of 2698 BC", hence the difference with the year 2697 BC calculated by the Jesuits.
