I. Dew Condenses and Turns White: What Is Cold Dew?

Cold Dew is the fifth solar term of autumn.

Around October 8th each year, when the sun reaches 195 degrees of the ecliptic, temperatures plummet and dew increases—Cold Dew has arrived. The Collected Explanations of the Seventy-Two Solar Terms records: “In the ninth month, the dew grows cold and is about to condense.” At this time, the dew is colder than during White Dew and is about to freeze into frost. In the north, forests are dyed in autumn hues, while in the south, the season deepens. It truly feels like “Autumn lengthens in the empty courtyard, Cold Dew brings evening sorrow.”
