Extra Life: How to Calculate Leap Moon Based on the Theory of "Bone"

The theory of "Weighing Bone" was created by Yuan Tiangang, a master in the Tang Dynasty, and it is also a secret that will never be passed down. The eight-character knowledge used in Treatise on Febrile Diseases and the fate decision in Zhouyi are a subject that we still don't understand. Next, I will introduce you how to calculate the leap month of the bone theory. Friends who want to know, please see below!

As we all know, there is a difference between lunar calendar algorithm and solar calendar algorithm. According to the December of the lunar calendar, the lunar calendar has only 354.4 days a year, which is less than the return of the solar calendar 10.9 days. In order to prevent the phenomenon of "snow falling in June" in some years, it is necessary to coordinate the seasonal relationship between the lunar calendar and the solar calendar. China adopted the "seventh leap month in the 19th year" in the Spring and Autumn Period. That is to say, in 19 tropic years (6939.6 days), seven leap months will be inserted into the lunar calendar, so that the cold and hot changes of the lunar calendar are basically consistent with those of the Gregorian calendar.

And 20 12 year happens to be the seventh month of the lunar calendar, so there are two July. In the theory of weighing bones, it can not explain the bone weight of people born in leap months. How to calculate the person born in leap month, should we use 0.9 beam in July or 0.5 beam in 6.5438+August?

Neither. Those born in the first half of leap month are counted as this month, and those born in the second half are counted as next month.

For example, a child born on July 20 12 14, July is 0.9 Liang.

Born on July 16 in leap month, it is 1.5 in August.

Note that the ancients used hours to measure time, and one hour is equivalent to two hours in modern times. There is a special hour at twelve o'clock, which spans two nights from11-01. If11-12 was born at night, it will be counted as the next day.

It is concluded that if there is a leap month, those born in the first half of the leap month are counted as this month, and those born in the second half are counted as next month. There are many sayings on the Internet, so let's learn about them together.
