In what month does summer start and end?

There are different criteria for dividing summer. In the northern hemisphere, it is June, July and August in the solar calendar. China is used to long summer as long summer, and meteorological summer will be postponed to long Xia Hou for about 25 days. In the southern hemisphere, 65438+February, 65438+ 10 and February are generally designated as summer. The ancients counted April, May and June of the lunar calendar as summer. Today, people regard June, July and August in the solar calendar as summer. Westerners generally say that the summer of solstice is divided into summer. Summer in China usually begins with a long summer and ends in early autumn. Long summer is the seventh solar term among the twenty-four solar terms and the first solar term in summer. The festival is held on May 5-7 of the Gregorian calendar every year. At this time, the bucket handle of the Big Dipper points to the southeast, and the longitude of the sun reaches 45. Long summer is an important solar term, marking the peak season for the growth of all things. Almanac: "The bucket refers to the southeast dimension and the long summer. Everything has grown up since then, so it is named Long Summer. " After the long summer, the sunshine increases, the temperature rises gradually, the thunderstorm increases, and the crops enter a vigorous growth stage.

Chang Xia said that saying goodbye to spring is the beginning of summer. Spring comes and summer grows, autumn harvests and winter storage, and in the long summer, everything is thriving. Because China has a vast territory and a large span from north to south, natural rhythms vary from place to place. In the long summer season, only the area south of Fuzhou-Nanling line in China enters the real summer of "the trees grow dark in summer and the balcony reflects into the pond"; And parts of the northeast and northwest just have the breath of spring at this time. According to the classification standard of modern climatology (climate average temperature) in China, the daily average temperature rises steadily to above 22℃, starting in summer.
