What season is the Millennium? Which solar term is the Millennium?

2. The Millennium is the fifteenth solar term in the "twenty-four solar terms". This solar term indicates the end of autumn and the beginning of Mid-Autumn Festival, and it is also an important festival reflecting the temperature changes in nature. When the sun reaches longitude 165 degrees, it is white dew, from September 7 to 9 in Gregorian calendar. The ancients used four seasons with five elements, and autumn was golden and golden white, so white was used to describe autumn dew. The Millennium solar terms basically ended the sultry summer, which was the turning point from sultry to cool in autumn. After a thousand years, the sky is high and the clouds are light, the wind is crisp and the temperature difference between day and night is large. At night, you will feel a little cold, and obviously feel that cool autumn has arrived.
