Principle of geomantic omen

The earth is constantly rotating, and the gas field of the whole earth, solar system and even the universe is constantly changing every day and year, forming different feng shui orientations at different times. This knowledge of choosing the orientation of feng shui according to the transformation of "time" is "regulating qi" The mastery of time depends on the astronomical calendar.

In the application of geomantic omen, it can be said that it is a basic skill to master the calendar accurately and skillfully.

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 all the year round, and has nothing to do with the moon phase. See the following table for the relationship between Gregorian calendar months and the 24 solar terms: the numerical order is12345678910112. Calendar months are silver moon, Uzuki, Chen Yue, Mitsuki, Wuyue, Wuyue, Yueyue, Yueyue and Ugly Moon, and all the 24 solar terms are beginning of spring.

Since the Great Cold, the Ganzhi calendar has been widely known to the government and people, and it has been used in astronomy, geomantic omen, numerology, choice and traditional Chinese medicine, and it has been recorded in the official almanac of 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. 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.

Sanyuanjiuyun is a way for ancient Han people to divide the big time. The ancestors looked up to astronomy and geography. After a long period of observation, they found that the movement of planets in the solar system will have an impact on natural and human phenomena on earth, especially the movement laws of Jupiter and Saturn. Jupiter orbits the sun for about 12 years, and Saturn orbits the sun for about 30 years. Jupiter and Saturn meet every 20 years. The ancient Han people knew this opportunity and took 180 as a positive element. Each positive element contains three elements, namely Shangyuan, Zhongyuan and Xia Yuan. There are three games every 60 years, each lasting for 20 years, that is, there are one, two and three games in Shangyuan, four, five and six games in Zhongyuan and seven, eight and nine games in Xia Yuan, thus forming a complete ternary and nine-game system.

Sanyun 1904- 1923 (Chen Jia to Guihai)

Satoshi Nakamoto

The 8th National Games 2004-2023 (from Shen Jianian to Guimao)

The 9th National Games (Chen Jiazhi Guihai)

The above is the approximate correspondence between the Gregorian calendar year and the dry and branch calendar years, and the division of years should be based on the dry and branch calendar years.
