"Sinus refers to the southeast, Wei refers to the long summer, and everything grows here, so it is named long summer." At this time, the longitude of the sun is 45 degrees. Astronomically, Chang Xia said that bidding farewell to spring is the beginning of summer days.

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 solstice in summer, the direct sunlight on the ground reaches the northernmost point of the year and almost directly reaches the Tropic of Cancer. At this time, the day in the northern hemisphere is the longest, and the farther north it is, the longer it is.

The summer solstice falls on June 2 1 or 22 every year. 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 the country, and the highest temperature in some areas can reach about 40℃.

Solstice is the earliest of the 24 solar terms. In the 7th century BC, the shadow of the sun was measured by civil soil gauge, thus the summer solstice was determined. The annual summer solstice begins on June 2nd1day (or 22nd) and ends on July 7th (or 8th). According to "Zunxian Manuscript", "The sun arrives in the north, the days are long and the shadows are short, so it is called the summer solstice. At best, it is excellent. " On the day of summer solstice, the sun directly reaches the northernmost part of the year, almost directly to the Tropic of Cancer (23 26' north latitude), and the daytime in the northern hemisphere reaches the longest, and the farther north it is, the longer it is. For example, the daily length of Haikou in Hainan is a little more than 13 hours, Hangzhou is 14 hours, Beijing is about 15 hours, and Mohe in Heilongjiang can reach 17 hours. From summer to the future, the position of direct sunlight on the ground gradually moves southward, and the daytime in the northern hemisphere is shortened day by day. There is a folk proverb that "eating noodles on the solstice in summer will shorten the day". At this time, the southern hemisphere is in the middle of winter.
