When is the slight cold solar term?

Taking 2024 as an example, slight cold began at 4: 49: 09 on June 6, 65438.

Slight cold is the 23rd solar term among the 24 solar terms, the 5th solar term in winter, the end of the second month of the dry calendar and the beginning of the ugly month. The longitude of the sun is 285 degrees, and it crosses the Gregorian calendar at 65438+1October 5-7 every year. Cold air accumulates for a long time and is cold. Slight cold means that the weather is cold but not extreme. Like severe cold, mild summer heat, severe summer heat and intense summer heat, they are all solar terms indicating temperature changes. The slight cold solar term is characterized by cold, but it is not extremely cold.

In the slight cold season, the direct point of the sun is still in the southern hemisphere, and the heat in the northern hemisphere is still in a state of loss. The heat absorbed during the day is still less than the heat released at night, so the temperature in the northern hemisphere continues to decrease. After the winter solstice, the cold air frequently goes south, and the temperature continues to drop, and the temperature drops to the lowest during the slight cold and severe cold in a year. There is a saying among the people called slight cold 239, which is shivering with cold, showing the cold degree of slight cold solar terms.

rural activity

Due to the large span between north and south in China, different regions will have different production agriculture for the same slight cold solar terms. There is not much farm work in most parts of the north, so we have winter vacation. The main tasks are heat preservation, fertilization and fertilizer accumulation in vegetable pits and sheds. In the south, winter fertilizer should be applied to crops such as wheat and rape, while in Hainan and most parts of South China, it is mainly to prevent cold and freeze and store fertilizer.

In ancient China, slight cold was divided into three stages: one was waiting for Yanbei Township, the other was waiting for magpies to start nesting, and the third was waiting for pheasants to start digging. The ancients believed that the geese among migratory birds migrated along the yin and yang. At this time, the yang moved, and the geese began to migrate north. At this time, magpies can be seen everywhere in the north, and they begin to build nests. The thrusting of pheasants means singing.
