What are the characteristics of Xiaohan solar term?

The Gregorian calendar year 2020 has passed, which means that the lunar calendar year 2020 is about to end. Before the end of the lunar calendar in 2020, we will have to experience Xiaohan and Dahan, the two coldest solar terms of the year. Among them, the Xiaohan solar term is tomorrow, January 5, 2021. So, what are the characteristics of Xiaohan solar term? What do we need to pay attention to? Let’s take a look!

Characteristics of Xiaohan solar term

The characteristic of Xiaohan solar term is the beginning of the coldest days of the year. Xiaohan is the 23rd solar term among the twenty-four solar terms, the fifth solar term in winter, the end of the Zi month and the beginning of the Chou month. Douzhizi, the ecliptic longitude of the sun is 285°, and it crosses between January 5 and 7 of the Gregorian calendar every year.

Cold air accumulates for a long time and becomes cold. Xiaohan means that the weather is cold but not yet extreme. Like the Great Cold, Minor Heat, Great Heat and End of Heat, it is a solar term that expresses changes in temperature. The characteristic of Xiaohan solar term is that it is cold, but it is not extremely cold.

After the winter solstice, cold air frequently moves southward, and the temperature continues to drop. The temperature drops to the lowest during the minor cold and major cold of the year. Folk proverb: "The time of Xiaohan is 239, the weather is so cold that the ground is so cold that I tremble." This illustrates the degree of coldness of Xiaohan solar term.

During the Lesser Cold season, the direct sunlight point is still in the southern hemisphere, and the heat in the northern hemisphere is still being lost. 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.

According to my country's long-term meteorological records, the Minor Cold solar term is colder than the Major Cold solar term in the northern region. There is a saying in the north that "the minor cold is better than the major cold"; but for most areas in the south, the lowest temperature throughout the year will still be Appears in the Great Cold solar term.
