When is the date of the summer solstice in 2020?
Summer solstice was also called "Summer Festival" and "Summer solstice Festival" in ancient times. The ancients said: "The days are long, the shadows are short and extremely extreme, so it is called the summer solstice." It is not only one of the 24 solar terms, but also a festival in the ancient folk "four seasons and eight festivals". Since ancient times, there has been a custom of worshipping gods and ancestors on the solstice in summer to pray for disaster relief and bumper harvest. When the sun moves to 90 degrees of the yellow meridian, it is the intersection of the summer solstice and the sun, which is nearly twice as much as the daylight saving time in the southern hemisphere of the solar calendar.
The summer solstice is the northernmost day of the sun in a year and the limit of the sun's northward movement. The solstice in summer is the turning point of the sun. After this day, it went back, and the direct sunlight point began to move south from the Tropic of Cancer (23 26' north latitude), and the days in the northern hemisphere became shorter day by day.
After the summer solstice, the Tropic of Cancer and its northern region, the midday sun altitude angle also began to decrease. At the same time, after the arrival of the summer solstice, the stars in the night sky gradually became summer stars.
