What year is Wuyin?

Wuyin year does not refer to a certain year. The15th year in the traditional calendar of China is called Wuyin year. Yin is the third branch of the earthly branch and belongs to the tiger, so it is called the Year of the Tiger. The most recent year is 1998, which circulates every 60 years.

In each calendar year, if the number of years is divided by more than 60 18, or the number of years is reduced by 3, the remainder divided by 10 is 5, and the remainder divided by 12 is 3. The years from beginning of spring to beginning of spring in the following year are "Wuyin Year". For example, 1938, 1998 and 2058 are all Wuyin years.

Brief introduction of trunk and branch chronology: The so-called trunk and branch chronology is literally equivalent to trunk and branches and leaves. In ancient China, the sky was dominant and the earth was subordinate. The connection between the sky and the trunk is called heavenly stems, and the connection between the ground and branches is called earthly branches. Together, it is called heavenly stems and earthly branches, or "dry branch" for short.

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 and 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 in a year.

Since ancient times, the trunk and branch calendars have been widely recognized by the government and people, and have been applied to astronomy, geomantic omen, numerology, choice and traditional Chinese medicine, and recorded in the official almanac of past dynasties (that is, the yellow calendar).

The chronology of cadres and branches starts from beginning of spring in the twenty-four solar terms, because the chronology of cadres and branches is the chronology of the calendar of cadres and branches. The same is true of the official almanac (that is, the Yellow Calendar). Since the Republic of China, the lunar calendar has only used branches to record the year, 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 a year.
