Gregorian calendar time: November 22nd, 2015
Lunar calendar date: October 11th Sunday< /p>
Every year on November 22nd and 23rd, it is regarded as light snow when the sun reaches 240° of ecliptic longitude. "The Collection of the Seventy-Two Hours of the Moon Order" says: "In mid-October, the rain falls and is thinned by the cold air. , so it condenses into snow. "The weather gradually becomes colder during this period, and the average first snow period in the middle and lower reaches of the Yellow River is basically consistent with the light snow season. Although it starts to snow, the amount of snow is generally small, and it freezes at night and changes during the day. If the cold air is stronger and the warm and humid air currents are more active, heavy snow may also fall. For example, from November 15th to 20th, 1993, there was heavy snowfall in some winter wheat areas in the north.
"Light snow" falls in the second half of November in the Gregorian calendar and in the second half of October in the lunar calendar. "Light snow" is a season that reflects weather phenomena. The ancient book "Qunfang Pu" says: "When it snows, the air is cold and it will snow. The ground is not cold enough and the snow is not heavy." This means that during the "Light Snow" festival, due to the cold weather, the form of precipitation changes from rain to snow, but this time At that time, because "the ground was not very cold", there was not much snow, so it was called light snow.
Light snow is the twentieth solar term among the twenty-four solar terms. On November 22 or 23, it means that snow begins to fall and the amount of snow is small. . Through the perpetual calendar we can see that the Xiaoxue solar term is November 22, 2015.
What does Xiaoxue mean?
Xiaoxue solar term to "Xiaoxue" is a solar term that reflects weather phenomena. The snow is light and there is no snow on the ground. This is the original meaning of the solar term "Xiaoxue". The ancient book "Qunfang Pu" says: "When it snows, the air is cold and it will snow. The ground is not cold enough and the snow is not heavy." This means that during the "Light Snow" festival, due to the cold weather, the form of precipitation changes from rain to snow, but this time At that time, because "the ground was not very cold", snow fell less often and the amount of snow was not large, so it was called light snow. Therefore, light snow indicates the starting time and extent of snowfall. Like rain and Guyu, light snow is a solar term that directly reflects precipitation.
Calculation formula of Xiaoxue date: [Y*D+C]-L
Formula interpretation: Y=last 2 digits of year, D=0.2422, L=leap year, 21st century C=22.36, 20th century=23.08.
For example: the date of light snow in 2088=[88×0.2422+22.36]-[88/4]=43-22=21, light snow on November 21. Exception: Add 1 day to the calculation for 1978.
What to eat during the light snow festival
