Ding Younian is one of the years in the lunar calendar, with a period of 6 years, for example, 1897, 1957 and 217 are all Ding Younian. Sixty Jiazi is the oldest dating method, and people born in Ding Younian are also called independent chickens.
Extended information
Ding Younian is one of the first jiazi in the lunar calendar, ranking 34th in the year of trunk and branch. The year before Ding You was the year of Bing Shen, and the year after Ding You was the year of the Reform Movement of 1898.
chronology of branches and branches
If Jiazi is the first year, Ugly B is the second year, and Bingyin is the third year ... 6 years is a week.
when the week is over, it will start from the year of Jiazi, and the cycle will continue.
heavenly stems and earthly branches:
Ten-day stems: A (ji ǐ), B (yǐ), C (bǐng), D (d ǐ ng), E (w ǐ 9;), J (jǐ), G (g ǜ ng), Xin (. Twelve earthly branches: Zi (zǐ), Chou (chǒu), Yin (yín), Mao (m ǐ o), Chen (chén), Si (s), Wu (wǔ), Wei (wèi) and Shen (shēn). Ugly: cattle; Yin: Tiger; 锛: Rabbit; Chen: dragon; 舵: snake; Afternoon: horse; Not: sheep; Shen: Monkey; Hey: chicken; Hey: dog; H: Pig. ）。 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".
The chronology of Ganzhi dates back to the early Han Dynasty. In the second year of Emperor Yuanhe of the Han Dynasty (AD 85), the court ordered the implementation of Ganzhi chronology throughout the country. From then on, the chronology of the branch and the year of the emperor were used together in the calendar of China traditional calendar. It is worth noting that the year of the trunk and branch and the conversion of the zodiac are based on the first day of the first lunar month and the Lunar New Year, and the provisions of beginning of spring's daily conversion are only applicable to numerology.
Gregorian calendar era number and the year of the main branch, for example, 1929 is the year of the past, 193 is the year of Gengwu ... and 1989 is the year of the past. The four years and the year of Geng Wu that we see on the calendar are arranged according to the method of trunk and branch chronology. In addition, it is worth noting that the year number belongs to the Gregorian calendar, which shall prevail according to the Gregorian New Year (the Gregorian calendar is on January 1st every year); The year of cadres and branches belongs to the lunar calendar, which is based on the lunar new year
, that is, the first day of the first month of the lunar calendar is converted every year, which is absolutely not to be confused. The two calendars are independent systems that have nothing to do with each other. Also, the chronology of cadres and branches must not be mixed with the Gregorian calendar date, otherwise it is a very serious fallacy.
2. The calendar month of the main branch
started in the twelfth lunar month of the pre-Qin period, so it is necessary to determine the geographical branch first: take the month where the winter solstice is located as the sub-month, and so on. In case of leap month, the earthly branch of last month is adopted. After determining the earthly branch, come down and 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 Wuchen, and so on; In the year of B or G, the first month is Wuyin; The first month of the year of C or Xin is Geng Yin, the year of D or Ren is Ren Yin, and the first month of E or decyl is Jia Yin.
the main branch of the first month is known, and the rest months can be inferred according to the order of sixty jiazi. The first day of each month (that is, the first day of the digital calendar month) is the starting point of the calendar month, and the same calendar month is used in the event of a leap month. This calendar month method has been adopted by officials in past dynasties.
3. the date of the dry branch
the first day of Jiazi, the second day of Ugly B, the third day of Bingyin ... 6 days is a week. After a week, it starts from Jiazi Day, and goes on and on. For example, the first day of the first month of the Lunar New Year (212 AD) is the day of Gui Shen, and the second day is the day of Jia Shen ... It happens to be 6 days on the first day of March, so the second day of March is the day of Gui Shen, and the third day is the day of Jia Shen.
in the Han calendar, the calendar of the cadres and the branches has never been interrupted or recorded in disorder, which is the longest calendar in China and the world. With a clearly recorded date, it can reach more than 27 years.
4. The earthly branches at the time of the year
are also certain, so 24 hours with twelve earthly branches are from 11: to 1: at night, 1: to 3: is ugly, and the rest are pushed. The day of the day is inferred from the heavenly stems on that day, and its songs are as follows:
A has given birth to A, B, G and C are the first,
C, Xin starts from E, and Ding, Ren, Geng, Zi lives,
Where is E, Ren is the real way.
that is, if the day belongs to Jia or himself, it should be matched with A as Jia Zi; If the day is B or G, it should be accompanied by C as C; On the day of Bingxin, Wu is the son of Wu; Ding Renri is a boxer; The day of Pentecox is a non-seed. When you know the main branches of your child, you can infer the rest.
It is worth noting that the birthdates algorithm used in traditional folklore is different from the trunk and branch of the calendar. The trunk and branch of the four-column annual column uses the node time of beginning of spring, and the trunk and branch monthly column uses the node time of beginning of spring, Jingzhe, Qingming, long summer, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Cold Dew, beginning of winter, Heavy Snow and Slight Cold. Note that it is not : on Boxing Day, so one.
