When is the solstice in the winter of 2020?

According to the astronomical calendar of China, the solar term "Winter Solstice" will be ushered in on February 2 1 day 18: 02 Beijing time. From this day on, China began to enter the "Nine Cold Days" season, which is also commonly known as "Entering Nine".

Every year around the Gregorian calendar 65438+February 22nd is the "winter solstice", the 22nd solar term among the 24 solar terms and the 4th solar term in winter. Contrary to the corresponding "summer solstice", on the "winter solstice", the sun is almost directly on the tropic of Capricorn with the shortest day and the longest night in the northern hemisphere. It was called "short day" or "short day" in ancient times. After the "winter solstice", the direct point of the sun slowly moved northward, and the days in the northern hemisphere gradually became longer and the nights gradually became shorter.

"Winter Solstice" is the key moment of yin-yang transformation in a year. When Yin Qi falls and Yang Qi rises, underground springs begin to sprout, which is a sign that winter is over and spring is coming. However, in the astronomical sense, "winter solstice" means that the severe winter should come in time. This is because during the winter solstice, the ground in the northern hemisphere loses more heat than it absorbs. Before and after the "March 9th", the area heat was minimized and the weather was coldest. Therefore, there is a saying that "1929 does not shoot, but walks on the ice in 3949" and "March 9 is cold".

People believe that "Qi begins at the Winter Solstice", so this is the best time to keep fit. "The winter solstice has been mended, and it is full of energy for a year. Pay attention to "tonifying kidney and preventing cold", eat more mutton, yam, lotus seeds, jujube and other foods to increase calories. In order to adapt to the law of "everything rests and the yang hides" in the cold winter, we might as well follow the principle of "going to bed early and getting up late, waiting for the sun" to save our strength. After lunch break, the yang is strong, which is the best time for exercise and health, but the intensity should be moderate, based on the principle of sweating slightly. " Winter solstice "health, focusing on nourishing the heart, should be calm, optimistic and open-minded, do not worry about trivial things, prevent premature aging, maintain vigorous energy, in order to live longer."
