When will the sun set on the solstice in the summer of 2020?

From the summer solstice of 2020, the sun sets at 12 seconds at 6: 43 pm. Solstice is the earliest of the 24 solar terms. Every year on June 20th, or 2 1, or 22nd of the Gregorian calendar. In the 7th century BC, the shadow of the sun was measured by civil soil gauge, thus the summer solstice was determined.

Although the summer solstice has the longest day and the highest sun angle, it is not the hottest time of the year. Because, close to the surface of the heat, at this time still continue to save, did not reach the maximum time. As the saying goes, "Hot days are in dog days", and the real hot weather is calculated by summer solstice and beginning of autumn. From mid-July to mid-August, the temperature is the highest in all parts of China, and the highest temperature in some areas can reach about 40 degrees. From summer to the sun, the sun directly reaches the northernmost point of the year, almost directly to the Tropic of Cancer (23 27' north latitude), and the daytime in the northern hemisphere is the longest, and the farther north it is, the longer it is. After the summer solstice, the position of direct sunlight on the ground gradually moved southward, and the days in the northern hemisphere became shorter and shorter.
