The 24 Solar Terms are a traditional Chinese system that divides the year into 24 equal parts, with each term marking a specific astronomical event or natural phenomenon related to the changing seasons. The system is based on observations of the sun’s annual movement and has been used in agriculture, meteorology, and cultural practices in China for over 2,000 years. The 24 Solar Terms are still widely used today to guide agricultural activities, such as planting and harvesting, and to mark seasonal festivals and events.
