the solar term of the autumnal equinox in 2021 is 3:20:55 on September 23 of the Gregorian calendar, and Thursday on August 17 of the lunar new year. The autumnal equinox is the 16th of the 24 solar terms and the fourth in autumn. At this time, the sun reaches the Yellow meridian 180 °; The festival is handed in on September 22-24 of the Gregorian calendar every year. On the autumnal equinox, "Fen" means "equinox" and "half". On the autumnal equinox, the sun is almost direct at the equator of the earth, and the length of day and night is the same all over the world. After the autumnal equinox, the position of direct sunlight moves to the southern hemisphere. The northern hemisphere gets less and less solar radiation, but more heat is lost on the ground, and the speed of temperature reduction is significantly accelerated. At the autumnal equinox, the summer heat has disappeared, the weather turns cool, and the summer heat is divided.


about the origin of the beginning of autumn


the beginning of autumn is the 13th of the 24 solar terms and the first solar term in autumn, which is handed over on August 7-9 of the Gregorian calendar every year. At this time, the handle of the Big Dipper pointed to the southwest, and the sun reached the Yellow longitude 135 °. The 24 solar terms reflect the change of "Qi" in the four seasons. The beginning of autumn is the node where Yang Qi gradually recedes and Yin Qi gradually grows, and gradually changes from Yang Sheng to Yin Sheng. The beginning of autumn also means that precipitation and humidity are at the turning point of the year and tend to decline or decrease; In nature, all things begin to grow from lush to bleak and mature. The beginning of autumn does not mean that the hot weather is over. The beginning of autumn is still in the hot season and has not yet gone out. The second solar term (summer treatment) in autumn comes out. The weather is still very hot in early autumn. The so-called "three volts of heat" also means "one volt after autumn". There is at least one volt of hot weather after the beginning of autumn. According to the calculation method of "three volts", the day of "beginning of autumn" is often still in the period of medium voltage, that is to say, the heat is not over, and the real coolness usually comes after the Bailu solar term. The watershed between hot and cool is not in the beginning of autumn.
