What is Bing Yinnian? What year is the year of Bing Yin?

The year of Bingyin is one of the 60 groups of trunk and branch years, which roughly corresponds to the Gregorian calendar year, such as 2 106, 2046, 1986, 1926, 1866, etc. (60 year cycle). In every AD year, if the number of years is divided by 60 or more, or the number of years is reduced by 6, the remainder of division by 10 is 0, and the remainder of division by 12 is 0. The year from beginning of spring to beginning of spring in the following year is "the year of the third year".

Extended data:

The chronology of cadres and branches starts from beginning of spring in the twenty-four solar terms, because it is the chronology method of the calendar of cadres and branches. The same is true of the official almanac of past dynasties (that is, the Yellow Calendar).

There is no doubt that the lunar calendar only uses branches to mark the year, which ranges from the first day of the first month to New Year's Eve. Lunar calendar and trunk calendar are two different calendars, which are different in the starting point of a year, the division rules of months and the number of days in each year. Due to the use of the Gregorian calendar after the Republic of China, many people, including a few so-called experts, lack calendar knowledge, so the two are often confused.

Because there is a corresponding relationship between the zodiac and the earthly branches, the zodiac is also counted from beginning of spring.

The trunk calendar is a calendar marked with 60 different heavenly stems and earthly branches, which is a unique solar calendar in China. It takes beginning of spring as the beginning of the year, and divides the year into twelve months with twenty-four solar terms. Every month contains two solar terms, and there is no leap month.

The dry calendar is related to the periodic movement of the earth around the sun, which can reflect the climate change throughout the year. Since ancient times, the Ganzhi calendar has been widely recognized by the government and the people, and has been applied to astronomy, geomantic omen, numerology, choice and traditional Chinese medicine, and recorded in the official almanac of past dynasties (that is, the Yellow Calendar).

Taking Qing Dynasty official history book Qing Shi Lu as an example, the chronology of official branches and departments in the book is divided into beginning of spring: for example, Zhonghua Book Company photocopied Book XVII of Qing Shi Lu and Book IX of Qianlong Shi Lu, page 573, beginning of spring (Geng Xu) on February 22nd, 2007/kloc-0.

"Historical Records" records: "Geng Xu. This is the beginning of last spring. " See also the ninety-fifth chapter of A Dream of Red Mansions in Qing Dynasty: "beginning of spring on December 18th of Jiayin year is December 19th of silver moon year". It is clearly pointed out here that the transition point of the dry calendar is in the year.

Heavenly stems and earthly branches:

Literally speaking, trunks and branches are equivalent to trunks and branches. In ancient China, the sky was dominant and the earth was subordinate. The connection between heaven and stem is called heavenly stem, and the connection between earth and stem is called earthly branch. Together, it is called heavenly stems and earthly branches, or "dry branch" for short.

There are ten heavenly stems, namely A, B, C, D, E, Ji, G, Xin, Ren and Gui, and twelve earthly branches, namely Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. The ancients put them together in the order of Jiazi, Ugly B and Bingyin (that is, the sky turns six times and the earth turns five times, which is just a cycle). Sixty pairs from Jiazi to Guihai are called Jiazi.

The ancient Chinese used these 60 pairs of branches to represent the serial numbers of years, months, days and hours, and this is the discipline of branches and branches.
