When are the sunrises and sunsets on the summer solstice?
Summer solstice is one of the 24 solar terms, which occurs on June 2 1 or 22 of the Gregorian calendar every year. On the day of the summer solstice, the sun moves to 90 degrees of the yellow meridian (in Gemini), and the position of the sun directly on the ground reaches the northernmost point of the year, almost directly on the tropic of cancer. At this time, the sunshine time is the longest in the northern hemisphere. In Beijing, the daytime can be as long as 15 hours. On this day, the northern hemisphere gets the most sunshine, almost twice as much as the southern hemisphere.
In ancient China, the summer solstice was divided into three phases: "the first phase of antlers decomposition; Second, wait for cicadas to start singing; Third-class Pinellia ternata. " Although Mi and Lu belong to the same family, the ancients thought they belonged to Yin and Yang. The deer's horn faces forward, so it belongs to Yang. On the solstice of summer, Yin Qi was born, and Yang Qi began to decline, so the front antlers began to fall off. Because mi belongs to yin, it falls in the corner of winter; After the solstice of summer, the male cicada fluttered and sang because of Yin Qi's feeling; Pinellia ternata is a shade-loving herb, named after it was born in swamps or paddy fields in midsummer.
