If you want to know more about May of the lunar calendar in 2019, come to Mr. Shui Mo!When is the summer solstice in 2019?The date of the summer solstice in 2019 is: Friday, June 21, 2019, 23:53:45The time of the summer solstice in 2019 is the lunar calendar: May 19, 2019 23:53:45 The summer solstice is one of the 24 solar terms, which falls between June 20 and 22 of the Gregorian calendar every year. On the summer solstice, the sun moves to 90 degrees of ecliptic longitude (the summer solstice point, currently in Gemini), and the position of the sun directly above the ground reaches the northernmost point of the year, almost directly above the Tropic of Cancer. At this time, the daylight hours in all parts of the Northern Hemisphere reach the longest of the year. For areas on and north of the Tropic of Cancer, the summer solstice is also the day when the sun is highest at noon in the year. In Beijing, the daylight on the summer solstice can last up to 15 hours, and the sun's altitude at noon can reach 73°32′. On this day, the Northern Hemisphere receives the most solar radiation, nearly twice as much as the Southern Hemisphere. After the summer solstice, high temperatures and extremely hot weather often occur, which are prone to heatstroke, colds, cardiovascular and cerebrovascular diseases, air-conditioning diseases, skin diseases, diarrhea and other diseases. The summer solstice is also the "plum rain" season in the Jianghuai area, which can easily cause objects to mold, and the human body will feel weak and listless. Mosquitoes reproduce very quickly, and intestinal bacteria are also easy to breed. Is the summer solstice the longest day?Every year on June 21 or 22, the sun reaches 90 degrees of ecliptic longitude, marking the summer solstice. This solar term was first established in the Spring and Autumn Period from 722 BC to 481 BC.Scientifically speaking, on the summer solstice, the sun's direct position above the ground reaches its northernmost point of the year, almost directly above the Tropic of Cancer (23 degrees 27 minutes north latitude). The daylight in the northern hemisphere reaches its longest, and the further north you go, the longer it gets. On the summer solstice, the sun almost directly shines over the Tropic of Cancer, the daytime in the Northern Hemisphere is the longest, and the sun does not set all day long in the Arctic Circle and within it, forming the largest polar day zone. After this day, the position of direct sunlight moves southward, the daytime in the Northern Hemisphere gradually shortens, and the directions of sunrise and sunset also begin to move southward. At the Tropic of Cancer and in the areas to its north, the altitude of the sun at noon gradually decreases and the shadow of the sun gradually lengthens. However, since the energy radiated by the sun to the ground is still greater than the energy dissipated by the ground into the air, the temperature continues to rise in a short period of time. As the saying goes, "A good fate is not as good as good luck." A person's destiny is already determined, and the only thing that can be controlled is his or her "luck."
