Is the day as long as the night in summer?

No, the vernal equinox and the autumnal equinox are two days as long as the night. The solstice in summer has the longest day. After the summer solstice, the days are getting shorter and shorter, and the winter solstice is the shortest. After the solstice in winter, the days get longer and longer. The position of other solar terms in the time period determines the length of dark days in a day.

Summer is one of the twenty-four solar terms of the lunar calendar, and the sun is located in the yellow meridian 120. In the hot summer, China people have the custom of drinking tea, drying ginger, burning incense and drinking mutton soup.

In the summer heat, fireflies hatched, so the ancients thought fireflies were made of rotten grass. The second weather is that the weather becomes sultry and the land is wet. The third kind of weather is frequent thunderstorm, which weakens the heat and humidity, and the weather begins to transition to beginning of autumn.

Summer solar terms are in the "three volts", which is the period with the most sunshine and the highest temperature in China. Most parts of the country are dry and lack of rain, and the temperature in many areas is above 35 degrees, so the so-called "three stoves" are also the most prosperous.
