How to calculate the four pillars and eight characters of leap month?

For example, the first month is counted after beginning of spring, regardless of whether the New Year ends or not.

Another example is a leap in April, but after the long summer, it is considered as April's fate, and after the awning, it is considered as May, so it has nothing to do with leap. Sometimes leap in April, the first half of the month is April life, and the second half is May life, because the ear festival is over.

Year-on-year method: Party A comes first in C year and Party B comes first in E year. At the age of Bingxin, he went to Geng, Ding and Yin. If you ask where Wu Gui started, Jia Yin is a good pursuit. In the first year, C was the first. Jiaxu, the year that has passed, the first month, the main branch of the month is Bing Yin, and the second month is Ding Mao, so as to sort. Month table from the beginning of the year: years A, B, G, C, D, N, D, C, D, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D. 3. Starting from one day: A, B, G and C are the beginning. Bing Xin starts from E and lives in Geng Zi. You can't do it, but you can't. "Jiaji Jia Jia" means "Jiari, an auspicious day". The son's name is Jiazi, and the clown is "Ugly B". When the sun rises, the date will be displayed (23~ 1). Jiazi Bingzi Wuzi Gengzi Renzi Ugly (1~3) Ugly Ding Ugly Xin Ugly Yu Ugly Yin (3~5) Bingyin Wuyin Gengyin Renyin Jiayin Mao (5~7) Ding Mao Jimao Xin Mao Gui Mao Chen (7) 9 ~/. According to the year, March was called "Chen Wu", according to the calendar, March 13 was the day of "Wushen", and according to "Wurigan", the time of discovery was "Renzi". In fact, the "birthday" or "eight characters" of a birthday is another way of saying "four pillars" in Zhouyi. Four pillars refer to the time when a person was born, that is, year, month, day and hour. In order to get the correct time of birth, the sundial is the most accurate measurement during the day. When the clock time is the artificial average time and the regional standard, it is necessary to calculate the "apparent solar time difference" according to the solar terms (ecliptic) and the "local longitude time difference" according to the place of birth, so as to get the real astronomical birth time. In the eight characters, the annual and daily branches are continuous and true; The branch of month and time is calculated according to the branch of year and day, which can be said to be virtual. Birthday can only reflect the date of a person's birth at most, so it is not too much to record the time. Some people use birthdays to tell fortune, which is very unreliable. Because a person's fate is influenced by many conditions, besides the weather, there are also restrictions on the region and people he grew up in. Coupled with the different opportunities, how much can the influence of birth time account for? Arrange four columns in a figure of eight, which refer to the year, month, day and hour of a person's birth respectively. Four-column arrangement refers to finding a person's date of birth. It is mainly divided into four steps. Chronological columns, that is, the year when a person was born, are represented by branches. Note that the dividing line between last year and next year is based on the intersection time of beginning of spring, not on the first day of the first month. For example, someone was born at 22: 00 on February 4, 2000 in the solar calendar. Since the lunar calendar was handed over to beginning of spring at 20: 32 on February 4, 2000, this person's date is the year of Chen Geng in 2000, not 1999. The general algorithm of chronological column: the numbers from A to the deck of the sky stem correspond to 4, 5, 6, 7, 8, 9, 0, 1, 2, 3 respectively, and the numbers from the ground branch to Hai correspond to 4, 5, 6, 7, 8, 9, 10,1respectively. One year's trunk algorithm takes the last digit as the trunk, and the ground branch is the remainder of one year divided by 12. Take 19 78 as an example. The last digit of 1978 is 8, the stem is E, and the remainder when 1978 is divided by 12 is 10, and the corresponding branch is noon, so 1978 is noon. Simple algorithm of chronology: the premise of this method is to know which zodiac year it is, which is generally used for fast calculation in recent years. Take 2009 as an example. As we all know, 2009 is the Year of the Ox. Since it is a cow, the earthly branches are of course ugly, and the last nine years of 2009 correspond to heavenly stems, so 2009 is an ugly year. Arranging moon columns and moon columns means using branches to represent the festival of people's birth. Note that the monthly branch is not divided by the first day of each month in the lunar calendar, but by festivals. Before the handover, it was the festival of last month, and after the handover, it was the festival of next month. 1 month (silver moon) from beginning of spring to Jingzhe, February (Uzuki) from Jingzhe to Qingming, March (Chen Yue) from Qingming to long summer, April (Mitsuki) from long summer to awning, May (noon) from awning to light summer, June (non-month) from light summer to beginning of autumn, and July (Shen Yue) from beginning of autumn.
