2007 is the Year of the Earth Pig, and the Year of the Golden Pig is a hype.
According to Zhao Zhiheng, director of the Tianjin Astronomical Society, there has only been one "Year of the Golden Pig" in 60 years. The last "Year of the Golden Pig" was in the "Year of Xinhai" in 1971, and the next "Year of the Golden Pig" was in the "Year of Xinhai" in 2031. The upcoming "Year of the Pig" in the lunar calendar is the "Year of Dinghai", and people born in this year belong to the "earth pig".
Zhao Zhiheng said that the ancient Chinese calendar used stems and branches to record the year. During the Southern and Northern Dynasties, 12 kinds of animals were found and the 12 earthly branches were labeled one by one, called the "Twelve Zodiac Signs." The "Stem and Branch Calendar" is also connected with the "Five Elements".
The five planets in the sky: Venus, Jupiter, Mercury, Mars, and Saturn. Ancient astronomers formulated the "Five Elements Chart of Sixty Years", so that each year corresponds to a planet, with a cycle of 60 years. For example, "Jia Zi" and "Yi Chou" correspond to Venus, and people born in these two years belong to "Golden Rat" and "Taurus Ox".
After this calculation, the lunar year of 1971 is Xinhai, and people born in it are "golden pigs"; the lunar year of 2007 is Dinghai, and people born are "earth pigs"; the lunar year of 2019 is Ji. People born in Hai are "wooden pigs".
