What time is the Autumnal Equinox in 2020?

The Autumnal Equinox in 2020 is at 21:14 on September 22, 2020 in the Gregorian calendar, and August 6 in the Gengzi year in the lunar calendar.
Autumnal equinox is the sixteenth solar term in the twenty-four solar terms, and usually falls on September 22-24 of the Gregorian calendar every year.
On the day of the autumnal equinox, the sun reaches 180° of ecliptic longitude (the autumnal equinox point), almost directly shining on the Earth's equator, and the day and night are equal in length everywhere in the world (not considering the refraction of sunlight by the atmosphere and the twilight shadows).
There is an ancient saying that "in spring, people worship the sun, and in autumn, people worship the moon". The Autumnal Equinox was once a traditional "Moon Worship Festival".
After the autumnal equinox, the sun's direct point continues to move from the equator to the southern hemisphere, and the days begin to become shorter and the nights longer in all parts of the northern hemisphere, that is, the day begins to be shorter than the night within a day; the opposite is true in the southern hemisphere. Therefore, the autumnal equinox is also called the autumnal equinox.
At the North and South Poles, on the day of the autumnal equinox, the sun stays above the horizon all day.
After that, as the sun's direct point continues to move south, a six-month polar night begins near the North Pole, gradually expanding and then shrinking in scope; a six-month polar day begins near the South Pole, gradually expanding and then shrinking in scope.
On June 21, 2018, the State Council issued its approval to establish the "China Farmers' Harvest Festival", agreeing to establish the autumnal equinox every year as the "China Farmers' Harvest Festival" starting from 2018.

Calculation method of autumnal equinox date

Calculation formula: [Y×D+C]-L Formula interpretation: Y=last 2 digits of the year, D=0.2422, L=leap year number, in the 21st century C=23.042, in the 20th century C=23.822.
For example: The date of the autumnal equinox in 2088 = [88×0.2422+23.042]-[88/4]=44-22=22, September 22 is the autumnal equinox. Exception: For 1942, add one day to the result.
