Ding Mao

Ding Mao is one of the main branches, ranking fourth. The former is Bing Yin, and the latter is Chen Wu. On yin and yang and five elements, the heavenly stem belongs to the fire of yin, and the foundation of earthly branch belongs to the wood of yin, which is the fire of wood. Yin Na and the Fire in the Furnace of Five Elements.

The fourth year of a cycle in the traditional calendar of China is called "Ding Mao Year". In each calendar year, if the number of years divided by 60 is greater than 7, or the number of years is reduced by 3, the remainder divided by 10 is 4, and the remainder divided by 12 is 4. The year from beginning of spring to beginning of spring in the following year is the year of Ding Mao.

Knowledge expansion:

The chronology of cadres and branches begins in beginning of spring with 24 solar terms, and 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.

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).

Take Qing Dynasty official history book Qing Shi Lu as an example. The official editing years in the book are divided into beginning of spring: for example, Zhonghua Book Company photocopied Book 17 of Qing Shi Lu, Book 9 of Qianlong Shi Lu, with 573 pages, beginning of spring, 20071February 22 (Geng Xu), and Record is recorded as: "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.
