Is cold dew and white dew a solar term?

White dew and cold dew are both autumn solar terms in the twenty-four solar terms, but they are not the same solar terms.

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.

"Twenty-four solar terms" said: "August Festival ... Yin Qi is getting heavier and heavier, showing white." As the weather gets cold, you will find many dewdrops on the ground and leaves in the morning. This is because water vapor condenses on it at night, so it is named Bailu. The ancients used four seasons with five elements, and autumn was golden and golden white, so white was used to describe autumn dew. Entering the "Millennium", I will feel a little cold at night.

The Millennium is one of the twenty-four solar terms in the lunar calendar, and it is called the Millennium solar term when the sun reaches 165 degrees. Millennium is the third solar term in autumn, marking the end of Qiu Meng and the beginning of Mid-Autumn Festival.
