What year is the lunar calendar in 202 BC?

The second year of a cycle in traditional calendar years in China is called "ugly year". In the following AD years, if the number of years is divided by more than 60, or the number of years is reduced by 3, the remainder divided by 10 is 2, and the remainder divided by 12 is 2. The years from beginning of spring to beginning of spring the following year are all "Ugly Year".

The chronology of cadres and branches began in beginning of spring in the twenty-four solar terms, and the chronology of cadres and branches is the calendar chronology of cadres and branches. The same is true of the official almanac (that is, the Yellow Calendar). After the Republic of China, the year number of the emperor was abandoned, so it was impossible to adopt a new chronology. It is indisputable that the lunar calendar can only record the year with branches and branches, and its year range is from the first day of the first month to New Year's Eve.

However, the lunar calendar and the trunk calendar are two different calendars, and they are different in the starting point of a year, the rules for dividing months and the number of days in a year. Due to the use of the Gregorian calendar after the Republic of China, many people lack calendar knowledge, so they often confuse the calendar with the lunar calendar.

Heavenly Stems and Earthly Branches

Heavenly stems and earthly branches, referred to as Ganzhi for short, originated from the observation of astronomical phenomena in ancient China. Ten dry words: encounter, enlightenment, gentleness, firmness, harmony, Tu Wei, Shang Zhang, heavy light, mystery, sunshine. Twelve branches: Kun Dun, Chi Fenruo, She Tige,,, Luo,,, Qitan, Zuo Meng, and Dayuanxian.

The simplified heavenly stems and earthly branches: "A, B, C, D, E, Ji, G, Xin, Man and Ghost" is called the ten heavenly stems, and "Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai" are called the twelve earthly branches.

Ten heavenly stems and twelve earthly branches are matched in turn to form sixty basic units, and they cooperate with each other in a fixed order to form the chronology of the stems and branches. Heavenly stems and earthly branches's invention had a far-reaching impact, and heavenly stems and earthly branches still uses it today, for calendar, technology, calculation, naming and so on.
