Is it the same day every year? Is it a solar term of nine points?

After the beginning of winter solar term, people entered the winter, and Xiaoxue solar term is the second winter solar term after beginning of winter solar term. So every year is the same day? Is light snow a nine-solar term? Let's go and have a look!

Is it the same day every year? number

Xiaoxue is the twentieth of the twenty-four solar terms. The time is165438+1October 22 or 23 of the Gregorian calendar every year, that is, when the sun reaches 240 degrees of the yellow meridian. "Light snow" is a solar term reflecting the climate characteristics. During the light snow solar term, a relatively stable meridional circulation has been established in East Asia, and low pressure or trough often appears in Siberia. When moving eastward, there will be a large-scale cold air going south, and there will be a large-scale gale and cooling weather in eastern China. Light snow solar term is a solar term with high frequency of cold wave and strong cold air activity. The light snow solar term does not necessarily snow, but refers to the light snow season, when the temperature drops to the point where it can snow. However, because the surface temperature is not low enough, even if it falls, the snowfall will be small or even absent. So whether it will snow this day depends on the current weather.

Is the light snow solar term nine solar terms? number

This is a folk method in China to calculate the flowering date in cold weather and spring. Counting nine means counting from the date of winter to Sunday (also called counting from winter to Sunday), counting nine every nine days, and so on. As the saying goes, "it's hot in dog days, but cold in dog days", and the coldest period in a year is "dog days". The light snow solar term is after the winter solstice, so it is a solar term within the nine solar terms. The correct algorithm of "counting nine" begins from winter to the first nonunion day in the future. Therefore, the specific date of "September" every year is not fixed, depending on the first nonyl day after the winter solstice. Another mistake is that the number nine is counted from the date of winter solstice, so the specific time of nine is fixed every year from the date of winter solstice, and each nine is fixed on the ninth day, 18 and the 27th day after winter solstice. The algorithm of counting nine from winter to day is wrong. As the saying goes, "Summer solstice is three years old, and winter solstice is nine years old."
