“Autumn Equinox” this year is”the earliest” in 124 years

At 21:31 on September 22, the”autumn equinox” solar term will usher in, which is a solar term that heralds a bumper harvest. Astronomical experts say that this year’s”autumn equinox” time is the earliest year since 1896 AD. Shi Zhicheng, a member of the Chinese Astronomical Society and director of the Tianjin Astronomical Society, said that the time the earth revolves around the sun is called a”tropical year” or”solar year”, and the path of the sun against the starry sky is called the”ecliptic.” Since ancient times, the”Vernal Equinox” has been set as 0 degrees, and every 15 degrees of the sun on the”ecliptic” is defined as a solar term or a middle air. The twenty-four solar terms are therefore 24 specific moments instead of specific 24 days.”Autumn Equinox” is the fourth solar term in autumn and the 16th solar term in the twenty-four solar terms.
