The Chinese solar terms, also known as the 24 solar terms, are an ancient agricultural calendar system that has been used in China for over 2,500 years. This system divides the year into 24 periods, each representing a specific time in the solar cycle. These terms are not only a reflection of the natural rhythm of the Earth but also a rich part of Chinese culture and tradition.

The concept of the solar terms originated during the Shang Dynasty (1600-1046 BC) and was further refined during the Zhou Dynasty (1046-256 BC). The ancient Chinese observed the changes in the sun’s position and its effect on the climate, agriculture, and natural phenomena. By dividing the year into 24 periods, they were able to predict and prepare for the changing seasons and agricultural activities.
