It is one of the main branches, and the order of sixty jiazi is ninth, the former is, the latter is, and the sound is "Feng Jianjin".
People who belong to monkeys are the ninth in heaven and the ninth in earth. Ren means Ren, which means that Yang is in charge of everything.
Shen means body, that is to say, all bodies have reached it. The ninth year of a cycle in China's traditional calendar is called "Ren Shennian".
I. Ren Shennian
The ninth year of a cycle in China's traditional calendar is called "Ren Shennian". In the following lunar year, the number of years divided by more than 60 12, or the number of years subtracted by 3, the remainder divided by 10 is 9, and the remainder divided by 12 is 9. The years from the first day of the first month of that year to the New Year's Eve of the following year are all "non-applicable years".
Lunar calendar is a dry calendar, and solar terms are used to guide agricultural production. Branches and branches are not divided into solar terms, regardless of traditional habits or official calendars (see the perpetual calendar compiled by Purple Mountain Observatory of Chinese Academy of Sciences for details).
Second, dry calendar
The trunk calendar, also known as ephemeris and Jiazi calendar, is an ancient calendar that marks the year, month and day with 60 different groups of heavenly stems and earthly branches.
Ganzhi calendar has a long history, extensive and profound, and contains profound cosmic astrological codes. The trunk calendar is mainly composed of four parts: trunk calendar year, trunk calendar month, trunk calendar day and trunk duration. From beginning of spring to the next beginning of spring, it is one year old, beginning of spring is the beginning of the year, and the solar term is the beginning of the month.
Ten heavenly stems and twelve earthly branches are collocated in turn to form sixty basic units and a sixty-week calendar; December and twenty-four solar terms are its basic contents. Years old is divided into December building (December order) in the official calendar, and "building" represents the direction of the top of the bucket handle of the Big Dipper; Twenty-four solar terms and December construction are the basic contents of the dry calendar.
Third, the daily branch calculation
People often use the algorithm of calculating New Year's Day's trunk and branch, and then calculate the trunk and branch of a certain day in the solar calendar, so we must first know the trunk and branch of New Year's Day. Because the daily trunks and branches circulate every 60 days, there are 365 days in a normal year and 366 days in a leap year in the solar calendar. If we know the trunks and branches of New Year's Day in one year, we can deduce the trunks and branches of New Year's Day in the next year and their ordinal numbers among 60 flowers: average year plus 5, leap year plus 6.
