Introduction
Chinese solar terms, also known as the 24 solar terms, are an ancient system of timekeeping that divides the year into 24 periods, each approximately 15 days long. These terms were developed based on the changes in the position of the sun relative to the Earth, and they are deeply rooted in Chinese culture and agricultural practices. Understanding Chinese solar terms can provide insight into the rich cultural heritage of China and its connection to nature.
