ZH_5_21 — Precession of the Equinoxes: The Great Year and Ancient Awareness
The precession of the equinoxes — the slow westward drift of the vernal equinox point along the ecliptic, completing a full cycle in approximately 25,772 years (the "Great Year" or "Platonic Year") — is the longest astro
ZH_5_16 — Eclipse Prediction and the Saros Cycle
The Saros cycle — a period of approximately 6,585.3 days (18 years, 11 days, 8 hours) after which the Sun, Moon, and lunar nodes return to nearly identical relative positions — has been the primary tool for eclipse predi
ZH_1_18 — Ancient Eclipse Prediction
The ability to predict eclipses — among the most dramatic and terrifying celestial events visible from Earth — represents one of the earliest triumphs of systematic astronomical observation and mathematical reasoning. [K
ZH_1_17 — Precession Discovery Timeline
Axial precession — the 25,772-year wobble of Earth's rotational axis tracing a circle among the stars — causes the vernal equinox point to shift approximately 1° every 71.6 years against the zodiacal background. Hipparch
