The Millennium is the fifteenth solar term in the "twenty-four solar terms". This solar term indicates the end of Mengqiu season and the beginning of Mid-Autumn season, and it is also an important festival reflecting the temperature changes in nature.

When the sun reaches the longitude 165 degrees, it is white dew, and it will be in the Gregorian calendar on September 07-09. The ancients used the four seasons to match the five elements, and autumn was golden and golden white, so white was used to describe autumn dew. The Millennium solar term basically ended the sweltering heat in summer, which was a turning point from sultry to cool in autumn. After the Millennium, the sky is high, the clouds are light, the air is cool and the air is cool, and the temperature difference between day and night is large. At night, you will feel a little bit cold, and obviously feel that cool autumn has arrived.
