2020 is the year of the rat. What year was it called in ancient times?

2020 is the year of Gengzi, and the ancient calendar of China marked the year with tree trunks and branches. During the Southern and Northern Dynasties, 12 species of animals were discovered, and 12 earthly branches were marked one by one, which was called the "Zodiac". The branch chronology is also connected with the five elements, which refer to the five planets in the sky: Venus, Jupiter, Mercury, Mars and Saturn.

China lunar calendar determines the date and month according to the moon phase and the age according to the 24 solar terms. There are 24 solar terms from 1 winter to the 24th, and the odd ones are called Zhongqi. The 24 solar terms reflect the annual movement of the sun. Because the number of days in1February is not old enough and has exceeded1March, leap months are added in time for adjustment.

A year with a leap month is also called a lunar leap year, which includes 13 lunar months. The year of the rat in the China lunar calendar includes a "leap April". The rule of adding leap month is that every month, any month containing neutral gas is considered as a normal month, and any month without neutral gas is considered as a leap month of the previous month. The "leap April" of the Lunar Year of the Rat is the leap month of last month.

Su Yi said that the average annual length of solar calendar and lunar calendar is the same, but their starting points are very different. For example, on June 65438+1 October1Gregorian calendar in 2020, the first day of China Lunar Year of the Rat begins on June 65438+1October 25, 2020. During this period, the Lunar Year of the Pig has not finished, so the children born during this period are still pigs rather than rats.
