The Gregorian calendar date of frost in 2022 is October 23 at 18:35:31, Sunday, the twenty-eighth day of the ninth lunar month.
Frost Descent is the eighteenth solar term among the twenty-four solar terms and the last solar term in autumn. Every year around October 23 of the Gregorian calendar, the sun reaches 210 degrees of ecliptic longitude, which is the beginning of the "Frost Descent" solar term.
In the frost season, hoarfrost has appeared in the Yellow River Basin of my country. On the fertile fields thousands of miles away, a piece of silver ice crystal shines. At this time, the leaves are yellow and falling. The ancient book "Explanation of the Twenty-Four Solar Terms" says: "When the air is calm and frost falls, the clouds begin to condense." It can be seen that "frost falls" means that the weather gradually becomes colder and frost begins to fall.
Frost phenological characteristics
A jackal is a sacrificial beast
The term "jackal is a sacrificial beast" first appeared in "Yi Zhou Shu": "Frost Descendence" On that day, jackals are sacrificed animals.” It is also said: "The jackals do not sacrifice animals, and their claws and teeth are bad." It means that during this solar term, wolves begin to capture prey, and sacrifice the prey to the beasts. The beasts are sacrificed to the gods, and the square pavement is used to sacrifice autumn gold. Just like the harvest of new grains in the world, they are used to offer sacrifices to heaven as a reward and to pray for good weather in the coming year. This is the meaning of the beast, and it is also the essence of man.
In the second period, the grass and trees yellow and fall
At the end of autumn, all the grass has dried up, and butterflies are flying in the frost. In autumn, the west wind blows, causing the leaves to fall and the grass to wither. The increasingly cold climate has destructively destroyed all the vitality of nature. The green color fades and the red disappears, and the wild geese disappear without a trace. And people's emotions have also entered a deep trough. The sadness of separation, the bitter wind and rain, all show the sorrow of late autumn and touch people's hearts.
The third phase of stinging insects is salty
The stinging insects all stay motionless in their holes, hanging their heads and entering a state of hibernation. Nature at this time is a kind of silent beauty. After the vibrant spring, the bustling summer, and the festive harvest autumn, the cycle of life has entered a dormant state again. The bees and butterflies are nowhere to be seen, and the stings of insects are silent, all preparing for a long winter. It is a spiritual practice, looking forward to the new life in the coming year.
