二十四节气
24 Solar Terms
Chinese Philosophy · conceptThe 24 solar terms (二十四节气) are a traditional Chinese calendar system that divides the solar year into 24 periods of approximately 15 days each, based on the sun's position in the zodiac. Formalized during the Han dynasty and recorded in the Huainanzi (139 BCE), each term reflects seasonal changes in climate, agriculture, and natural phenomena. The system was declared a UNESCO Intangible Cultural Heritage in 2016. Unlike the lunar calendar, solar terms are based on the tropical year — the same astronomical foundation as the Western calendar.
Within the vast Chinese philosophical tradition, from the Hundred Schools of Thought to the classical texts that shaped East Asian civilization, 24 Solar Terms represents a key concept that continues to inform philosophical thought and practice today.
