What is the origin and method of the ecliptic?

The ecliptic, originally an astronomical term, refers to the great circle where the earth's orbital plane around the sun intersects with the celestial sphere. Because the earth's revolution is attracted by other planets, the moon and other celestial bodies, the position of the ecliptic plane in space changes irregularly. Because the earth revolves around the sun for one year (365.438+09 days), the ancients divided the year into 24 segments according to the position change of the sun on the ecliptic and the evolution order of the ground climate, which was divided into 65.438+02 months. Therefore, it is normal that the "twelve constellations" based on the moon reflect the influence of cosmic celestial bodies every day (reflecting that the earth runs well on the ecliptic).

Nowadays, there are many mistakes in the printing of many books. For those who don't choose auspicious days, it is easy to make mistakes in choosing auspicious days, so we should learn the method of "auspicious days" in order to check whether there are any printing mistakes in the books. Moreover, if you don't need to consult relevant books or calendars, you can say one, two, three and four with a pinch of your finger or a frown anytime and anywhere, which will not only help others, but also show your "expert" demeanor and make you forget the method. Twelve satellites are built, divided, full, flat, fixed, held, broken, dangerous, successful, off, on and off in order.

Start method: Every year, from the first day after beginning of spring, "build", one person a day, in this order. Repeat the sacred value of the previous day in each festival; * * * Repeat 12 times a year, just to ensure that it will be built on the first day after beginning of spring next year. For example, in the first month, the first day of the first month is "construction", the second day is "division" and the third day is "full". The foundation is laid in February, the first benchmark day in February is "construction", the second day is "minute", and so on.
