What year were dragons born?
Judgment method—
When the number of AD years is divided by 12, all the years with a remainder of 8 are the Year of the Loong.
The formula is: the number of years in AD ÷ 12= a quotient, and the remainder is 8.
For example, if the quotient of 20 12÷ 12 is 167 and the remainder is 8, then the year of 20 12 is the Year of the Loong.
The Year of the Loong is counted from beginning of spring in the twenty-four solar terms, because the zodiac year is attached to the chronology of the trunk and branch, and the chronology of the trunk and branch is the chronology method of the trunk and branch calendar. The same is true of the official almanac of past dynasties (that is, the Yellow Calendar).
There is no doubt that the lunar calendar only uses branches to mark the year, which ranges from the first day of the first month to New Year's Eve. Lunar calendar and trunk calendar are two different calendars, which are different in the starting point of a year, the division rules of months and the number of days in each year. Due to the use of the Gregorian calendar after the Republic of China, many people lack the knowledge of the calendar, so the two are often confused.
Extended data:
Heavenly stems and earthly branches counts years-
Because heavenly stems and earthly branches cycles every 60 years, it is impossible to directly calculate the corresponding year value from the main branch. But we can calculate the corresponding year of 60 years according to the main branch, and then further calculate.
Let X be the corresponding sequence of heavenly stems, and the sequence of A-D is1-10; Y is the corresponding order of earthly branches, and sub-hai is 1- 12 in turn. Then the calculation formula of the corresponding order Z is: z = 6x-5y, and if it is negative, you can add 60.
Its calculation is based on congruence equations: z ≡ x (mod 10), z ≡ y (mod 12) and x ≡ y (mod 2), which is obtained by solving z≡36x+25y (mod 60) and further simplifying it.
The trunk calendar is a calendar marked with 60 different heavenly stems and earthly branches, which is a unique solar calendar in China. It takes beginning of spring as the beginning of the year, and divides the year into twelve months with twenty-four solar terms. Every month contains two solar terms, and there is no leap month. The dry calendar is related to the periodic movement of the earth around the sun, which can reflect the climate change throughout the year.
