Were you born in leap month 10 in' 84? What's the plan?

Reply 10# Questioning Dou's traditional leap-moon algorithm (example) (reposting) Dou's traditional leap-moon algorithm has always been a controversial topic. What should I do if I meet a leap month? Predecessors have their own unique skills, which can be summarized into six kinds: 1, counting by month according to the ancient method, which is the viewpoint of the Book of Doors, and is followed by most people; 2. Monthly; 3. The first15th day is counted as last month, and the second15th day is counted as next month; 4, get up on a monthly basis and order two rooms, and the month is still ranked in the previous month; 5. Add up the current month and leap month in the past 60 days and divide by them; 6. Determine the month of birth according to the solar terms. The ancients have long found that the 24 solar terms in a year are related to Beidou and the gathering of the sun and the moon. Every month, the sun and the moon meet once, which is a festival. When the sun and the moon meet, they will be in harmony. If Beidou doesn't meet the sun and the moon in that month, the solar term will not be established and it will become a leap month (see China Yi Xue). There is a passage in Zhang Guoxing Zong that "the moon helps bucket handle" (Landa Press, p. 19 1 page): Where the moon is built, it is what Kuixing of bucket handle pointed out. There are twelve seasons in a year, and the fight turns with the moon. As for the leap month, bucket handle refers to two days, covering the sun and the moon to run and fight. These two points actually show that leap month is not only determined by calendar, on the contrary, it is a natural phenomenon of heaven and earth. In the relationship between the bucket and the sun and the moon, the leap moon is an inevitable derivative phenomenon: at this time, the bucket does not meet the sun and the moon, and the handle of the bucket points to "between two days". In some perpetual calendars, the branch of leap month follows the branch of last month. This is equivalent to saying that leap month is counted as last month. It makes sense to calculate by month. After all, bucket handle refers to "between two Chen". How do you know that it belongs only to the upper Chen and not to the lower Chen? What happened? A textual research on the ephemeris quoted from Zhou Shu in central Hebei in Qing Dynasty pointed out: "When Qi should be there, there is no Qi in the leap (note: it is stipulated in the constitutional calendar), and bucket handle refers to the time between two dates. Therefore, one month before the leap, qi is in the dark (note: refers to the twenty-ninth or thirty days of the lunar calendar), and one month after the leap, qi is in the new moon (note: refers to the first or second day of the lunar calendar). When it is a leap month, the festival is in the middle of the month (note: it refers to a leap month without air, and its festival must be in the middle of the month). I used to do things in the first month and then in the second month, so I decided to be an adult at four o'clock. This passage is the only one I found in the voluminous ancient books about the handling of leap months, which is very precious and very reasonable. It clearly puts forward the rules for handling leap months: leap months should be based on the qi in the month and belong to the previous month and the next month respectively. However, practice is the only criterion for testing. After years of practice, the author found that the above viewpoints are inconsistent with the actual test. The author concludes that leap months should be included in the current month. 19 has only seven leap months, so there are really too few people born in leap months. I have met 8- 10 people, 3 of whom are colleagues or friends around me, who are familiar with them, and the rest are all known during online calculation. There are no mistakes in the month, so I won't list them here, because I'm not familiar with them (some didn't leave a message, but I met two people on the personality hotline of this forum. Here are three examples for your reference. **********************************************************
