What year is the garrison?
1. The 25th year of a cycle in the traditional calendar year of China is called "Wuzi Year". Divide the number of years by more than 60 and 28, or subtract 3 from the number of years. Divide by 10 and the remainder is 5. Divide by 12 and the remainder is 1. The year from beginning of spring to beginning of spring in the following year is the Year of Wuzi. Note that the saying that Wu Zinian originated from the first day of the first month was only after the Republic of China, which was different from the way used by ancient officials and people.
2. In ancient China, the sky was dominant and the earth was subordinate. The connection between heaven and stem is called heavenly stem, and the connection between earth and branch is called earthly branch. Together, it is called heavenly stems and earthly branches, or "dry branch" for short. The ancients in our country used these sixty pairs of branches to represent the serial numbers of year, month, day and time, and this is the branch calendar. The chronology of cadres and branches begins in beginning of spring with 24 solar terms, and it is the chronology method of the calendar of cadres and branches. The same is true of the official almanac of past dynasties (that is, the Yellow Calendar). After the Republic of China, the emperor's year number was abandoned, and the lunar calendar can only record the year with dry branches, which ranges from the first day of the first month to New Year's Eve, which is indisputable. 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 calendar knowledge, so they often confuse the calendar with the lunar calendar.
