The sixty-year Ganzhi cycle combining Ten Heavenly Stems and Twelve Earthly Branches.
The Sexagenary cycle (Ganzhi) is a 60-term cyclic coordinate system for recording time, direction, and cosmological harmony in China. Attested on Shang dynasty oracle bones from 1200 BCE, the system coordinates Ten Heavenly Stems (correlating with Yin-Yang and Five Elements) with Twelve Earthly Branches (correlating with the 12 zodiac animals: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig). Standardized by the Han dynasty, it remains the foundation of Four Pillars astrology (BaZi).
