Information about the 24 solar terms

The solar terms of 1 and 24 are a traditional time system in which ancient China people divided a year into 24 time periods according to the running track of the sun on the ecliptic, combined with climate, farming and natural phenomena. This unique time division method originated from the ancient farming culture and astronomical observation in China, which reflected the observation and cognition of ancient farmers on the changes of natural phenomena.

2. The history of the 24 solar terms can be traced back to the Shang and Zhou Dynasties in ancient China. At that time, people began to pay attention to the movement of the sun on the ecliptic. In particular, farmers hope to predict climate change through the movement of the sun and arrange agricultural activities reasonably. The ancient agricultural society was very dependent on the natural environment, and farmers needed to decide the time of sowing, harvesting and other agricultural activities according to the seasonal changes.

3. The division of solar terms is not simply based on the time interval of 15 days per month, but on the position of the sun on the ecliptic and climate change. Twenty-four solar terms are not only widely used in ancient times, but also a part of China traditional culture.
