When does Cold Dew start in 2020?

Solar term Cold Dew: Thursday, October 8, 2020 3:55:07. The 2020 Cold Dew began at 3:55:07 am on October 8.
In the Collection of Explanations of the 72 Seasonal Changes in the Lunar Calendar by Wu Cheng of the Yuan Dynasty, it is said: "In the ninth month, the dew is cold and is about to condense." This work explains Cold Dew as meaning that the temperature is lower than that during White Dew, the dew on the ground is colder and is about to condense into frost.
The "Pingqi Method" used in ancient my country divided Cold Dew into three phases: "The first phase is the arrival of wild geese; the second phase is the emergence of sparrows into clams; the third phase is the yellowing of chrysanthemums."
During this solar term, wild geese migrate southward in a line or V-shaped formation.
In late autumn, when the weather was cold and all the birds disappeared, the ancients saw many clams suddenly appear on the seashore. The stripes and colors of the shells were very similar to those of birds, so they thought they were transformed from birds.
The third phase, "chrysanthemums begin to turn yellow", means that chrysanthemums are generally in bloom at this time.

Notes on animal husbandry during the Cold Dew solar term:

The weather turns cold during the Cold Dew season, and livestock and poultry are more susceptible to disease. The following tasks should be done in livestock and poultry production:
Do a good job in epidemic prevention in autumn. It is a season when livestock diseases are prone to occur. It is necessary to carry out timely vaccination against epidemic diseases for pigs, cattle, sheep and rabbits.
As the weather turns cooler, cattle farmers must carry out breeding work in a timely manner to ensure that cows in estrus are fully pregnant.
This is the best season for grazing goats. It is best to graze them early and return them to the pen late to ensure they are in good fat condition for the winter.
Farmers raising Angora rabbits should speed up the autumn breeding work, breed more Angora rabbits, and improve the efficiency of rabbit breeding.
Professional cattle, sheep and rabbit farmers should plant ryegrass in time to provide cattle, sheep and rabbits with sufficient green feed for winter and next spring.
For those who specialize in raising laying hens and laying ducks, increasing artificial lighting can increase egg production.
October is the molting season for laying hens, and egg production decreases significantly. To speed up molting, you can reduce the food intake for about a week in the early stage of molting to cause malnutrition and promote hair loss; in the second half of the month, strengthen nutrition to encourage it to enter the peak egg-laying period as soon as possible.
Prevent the occurrence of livestock and avian influenza and take timely precautions.
