What festival is the Millennium?
The white dew is the fifteenth solar term in the twenty-four solar terms of the lunar calendar, and it is the white dew when the sun reaches 165 degrees. The time is around September 8 of the Gregorian calendar every year.
The origin of solar terms:
Millennium is one of the 24 solar terms of the lunar calendar. When the sun reaches 165 degrees, it is called the Millennium solar term. Millennium is the third solar term in autumn, marking the end of Qiu Meng and the beginning of Mid-Autumn Festival. Dew is water droplets formed by condensation of water vapor on the ground or near-earth objects due to temperature drop. So the Millennium actually indicates that the weather is getting cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees. Yang Qi reached its peak in the summer solstice, and these two extremes must be reversed, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew. As the saying goes, "eighteen pots of summer heat, not exposed to the Millennium." These two sentences mean that it is still hot in summer, so you must take a bath with a basin of water every day. After eighteen days, in the new millennium, don't be shirtless and naked, lest you catch cold. There is also a saying: "White dew and white fans, the autumn equinox is beautiful." This means that if there is dew before and after the white dew, the late rice will have a good harvest.
"White Dew" is a festival that reflects the temperature changes in nature. Dew is a unique natural phenomenon after the solar term of "White Dew". The weather at this time, as the Book of Rites said: "The cool wind comes, the dew falls, and cicadas sing." 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". The ancients also said in Xiao Weijing: "The fifteenth day after the summer heat is white dew", and the yin is getting heavier and heavier, and the dew condenses into white. In fact, meteorology shows that at this time of the solar term, the weather becomes cool and the sun is still very hot during the day. But as soon as the sun returns to the mountains, the temperature will drop rapidly. At night, the water vapor in the air will condense and form tiny water droplets, which are very densely attached to the green stems, leaves or petals of flowers and trees and are white. Especially after the morning sun exposure, it looks more crystal-clear and attractive, thus obtaining the beauty of "White Dew".
