Are cold dew and white dew the same solar term?

No, cold dew and white dew belong to the same solar term in autumn, but they are not the same solar term.

September 7th to 9th is the Millennium solar term, and1October 8th to 9th is the cold dew solar term. After the Millennium, the weather turned cold and dew began to appear. Speaking of cold dew, dew increases and temperature decreases. As the saying goes, the white dew does not show the body, and the cold dew does not show the feet. This proverb clearly points out the difference between the two. What is the difference between cold dew and white dew?

1, different times

Cold dew comes from 10 every year 10 from July 7 to 9, and white dew comes from September 7 to 9 every year.

The climate is different.

In the twenty-four solar terms, the explanation of cold dew is: in September, the dew is cold and will condense. This means that during this period, the temperature is lower than that in the white dew, and the dew on the ground is colder and will soon condense into frost. When it is white dew, the temperature will not be too low, but at night, it will produce a lot of dew.

3. These three periods are different

The ancients in China divided the cold dew into three stages: one stage was the swan goose; Second, the sparrow enters the water and becomes a clam; Three chrysanthemums have yellow flowers. According to the observation of nature, the ancients in China divided the Millennium into three stages: the first stage is when the geese come, the second stage is when the mysterious birds return, and the third stage is when the birds are ashamed.
