The solstice in summer is the longest day and the shortest night in a year. After the summer solstice, the days will get longer and the nights will get shorter. This is because the earth's orbit around the sun is not a complete circle, but an ellipse. There is also an inclination angle between the earth's rotation axis and the equatorial plane. It is for these two reasons that the earth receives different degrees of sunlight in different seasons.
When the earth revolves around the summer solstice, the northern hemisphere is closer to the sun and the southern hemisphere is farther away from the sun. This means that the northern hemisphere receives more sunlight, while the southern hemisphere receives relatively less. Because the daytime hours in the southern hemisphere have decreased, the daytime hours in the northern hemisphere have increased accordingly. Therefore, mathematically speaking, after the summer solstice, the days do get longer.
In addition to mathematical explanations, we can also feel the phenomenon that the days become longer from summer to the future from our life experience. You can notice that in the days after the summer solstice, it gets dark very late and the day lasts for a long time. This brings a lot of convenience and fun to our life. For example, you can go out for a walk, do outdoor activities or get together with friends later in the evening to enjoy the warmth of the sun and the beauty of nature.
The historical origin of the summer solstice can be traced back to ancient China. In ancient times, summer solstice was a very important solar term. People will hold various celebrations to welcome the arrival of the summer solstice. Summer solstice is considered as an important moment in agricultural production, because it marks the longest day in a year, that is, the most sunshine time. This is very beneficial to the growth and development of crops.
In the ancient farming society of China, the solstice in summer was the most important festival. People will hold sacrificial ceremonies, folk games and temple fairs. For example, some places will hold dragon boat races, and some places will hold dragon and lion dances to celebrate the summer solstice. These activities can not only increase people's entertainment and interaction, but also pin people's good wishes for a bumper harvest and a happy life.
After the summer solstice, the days become longer, which is caused by the special shape of the earth's orbit and the inclination angle between the earth's rotation axis and the equatorial plane. The summer solstice was a very important solar term in ancient China, and people welcomed it through various celebrations. Let's celebrate the summer solstice and enjoy the warmth and happiness brought by the sunshine!
