Zij

"Zij" refers to the calculations and mathematical methods used in traditional Chinese astronomy and astrology. Historically, it encompasses various systems for predicting celestial movements and their influence on earthly events, often organized into 28 segments called "lunar mansions" or "Ziji." These systems help in understanding celestial patterns, guiding activities like agriculture, navigation, and divination. While rooted in ancient practices, Zij also reflects systematic approaches to astronomy, blending observation and symbolism to interpret the cosmos’s impact on human affairs.
