Extended data
Ding Younian is one of the eldest sons of the lunar calendar, ranking 34th among cadres and branches over the years. The year before Ding You was the year of Bing Shen, and the year after Ding You was the year of 1898.
Chronology of cadres and branches
For example, Jia Zi is the first year, Ugly B is the second year, and Bing Yin is the third year ... Sixty years is a week.
Week after week, starting from the year of Jiazi, starting from the week, and starting again and again.
Heavenly stems and earthly branches:
Ten-day stems: A (ji ǐ), B (yǐ), C (bǐng), D(Dǐng), E (w ǐ), J (jǐ), G (G ǜ ng), Xin (xǐn). Twelve earthly branches: Zi (zǐ), chou (Chou), Yin (yín), Mao (m ǐ o), Chen (chén), Si (s), Wu (), Wei (wèi) and Shen (shēn). Ugly: cattle; Yin: tiger; Thumb: rabbit; Chen: Dragon; Rudder: snake; Afternoon: horse; No: sheep; Shen: Monkey; Hey: chicken; Hey: dog; H: pigs. )。 Ten branches and twelve branches are matched in turn to form sixty basic units. The ancients used this as the serial number of year, month, day and time, which is called "the discipline of branches and branches".
Ganzhizhi sprouted in the early Han Dynasty, and in the second year of Emperor Yuanhe of the Han and Yuan Dynasties (AD 85), the court ordered the implementation of Ganzhizhi throughout the country. Since then, the year of the branch calendar and the year of the emperor have been used together in the traditional calendar of China. It is worth noting that the conversion between the year of the official branch and the Chinese zodiac is based on the first day of the first lunar month and the Lunar New Year, and the beginning of spring daily conversion is only applicable to numerology.
Gregorian calendar era number and year of main branch, for example, 1929 is the past year, 1930 is the year of Wu Geng ... and 1989 is the past year. The four years and Gengwu years we see on the calendar are arranged according to the chronology of trunks and branches. It is also worth noting that the year number belongs to the Gregorian calendar, which is subject to the Gregorian New Year (Gregorian calendar 65438+ 10/); The chronology of cadres and branches belongs to the lunar calendar, according to the Lunar New Year.
The lunar calendar is converted on the first day of the first month of the lunar calendar every year. Never confuse it. These two calendars are independent systems and are not related to each other. Also, the chronology of cadres and party branches must not be mixed with the Gregorian calendar date, otherwise it is a serious fallacy.
2. Dry branches and the moon
It began in the twelfth lunar month in the pre-Qin period, so we must first determine the geographical branch: take the month where the winter solstice is located as the sub-month, and so on. If it is a leap month, the earthly branch of last month is adopted. After determining the earthly branch, then determine the heavenly stem: if you meet A or your own year, the first month is Bingyin, the second month is Ding Mao, the third month is Chen Wu, and so on; B or Geng Year, the first month is Wuyin; The first month of Year C or Year Xin is Geng Yin, the first month of Year Ding Nian or Year Ren is Ren Yin, and the first month of Year E or Year decyl is Jia Yin.
The main branch of the first month is known, and the rest months can be inferred in the order of sixty sons. The first day of each month (that is, the first day of a digital calendar month) is the starting point of a calendar month, and the same calendar month is used in leap months. This calendar method has been adopted by officials in past dynasties.
3. anniversary of dry branches
The first day of Jia Zi, the second day of Yi Chou, and the third day of Bing Yin ... 60 days a week. A week later, starting from Jiazi Day, it started again and again. For example, the first day of the first lunar month (20 12) is the day of ghosts and gods, and the second day is the day of Shen Jia ... The first day of March is exactly 60 days, so the second day of March is the day of ghosts and gods, and the third day is Shen Jiari.
In the "Han Calendar", the official calendar has never been interrupted, and there is no confusion. It is the longest calendar in China and even the world. With a clearly recorded date, it can reach more than 2700 years.
4. When drying branches
The earthly branches in one day are also certain, so the 24 hours of the twelve earthly branches are at night 1 1 point to 1 point, 1 point to 3 o'clock is ugly, and the rest are pushed. The day is inferred from the day, and its song is as follows:
A has given birth to a, and B, G and C come first.
Bing Xin started in Wu, and was destined to be a boxer.
You can't do it, but you can't.
That is, if the day is A or his own, the child should be accompanied by A when he was a child; If the day is b or g, it should be accompanied by c as c; On the day of Bingxin, Wu was the son of Wu; Ding Renri is a boxer; Pentecost is a seedless day. When you know your child's main branch, you can infer the rest.
It is worth noting that the birth date algorithm used in traditional folklore is different from the trunk and branch of calendar. In the four columns, the annual column of dry branches uses the node time of beginning of spring, and the monthly column of dry branches uses the node time of beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, Daxue and Xiaohan. Note that it is not 0 o'clock on Boxing Day, and a main and branch sun column can be used.
