What season is September 20th, 2020?

September 20th, 2020 is the millennium among the 24 solar terms, and there are still two days before the autumnal equinox, the 22nd autumnal equinox.

Millennium is the fifteenth solar term in the "twenty-four solar terms", which is the end of applying for the moon and the beginning of the unitary month in the calendar. When the sun reaches 165 degrees, it will cross the Gregorian calendar on September 7-9. After the Millennium solar terms, the yin and cold qi rises, the summer heat residual temperature in early autumn gradually dissipates, cold and hot alternate day and night, and the cold produces dew condensation. The ancients used four seasons to match five elements. Autumn belongs to gold, gold and white alternate with each other, and autumn dew is described in white, hence the name "White Dew".

Cold gives birth to dew, and "white dew" is an important solar term reflecting the growth of cold in nature. According to the explanation of "white dew" in the twenty-four solar terms-"water and soil condense dew, autumn belongs to gold, golden white and white dew, and qi begins to be cold". By the time the Millennium arrived, the sultry summer was basically over and the weather gradually turned cold.
