Excuse me, when did 1986 10 10 start to pay for the cold dew solar term on October 8?

Cold dew is the seventeenth solar term in the twenty-four solar terms of the lunar calendar, belonging to the fifth solar term in autumn, which indicates the official start of the autumn season; The time is1October 7-9, 10. When the apparent sun reaches longitude 195. "Twenty-four solar terms" said: "In September, the dew is cold and will condense."

Cold dew means that the temperature is lower than that of the white dew, and the dew on the ground is colder and will soon condense into frost. In the cold dew season, Nanling and the vast area to the north have entered autumn, the northeast has entered late autumn, and the northwest has entered winter or is about to enter winter. The temperature drops gradually. White dew, cold dew and first frost all indicate the phenomenon of water vapor condensation, and cold dew is the transition from cold to cold.
