Advanced Eclipse Engine 2.0 — a major leap to professional-grade accuracy. We rebuilt and recalibrated our physical eclipse engine against NASA’s Five Millennium Canon of Solar Eclipses (years 1–2999). Full catalog coverage: every reference eclipse found. Types match the canon in 99.9% of cases — only 17 events differ, at noise level against a multi-millennium catalog. Median timing error about 0.39 minutes; median duration error about 2.7 seconds. Versus NASA, median gamma error is about 0.0009 Earth radii and median magnitude error about 0.0008. Our hybrid detector found every hybrid eclipse across those three millennia (295/295), with the same high fidelity as total, annular, and partial types. The engine uses only physical principles and formulas — not ad-hoc heuristics: Earth–Moon–Sun geometry is modelled in a single physical framework. It is one of the few eclipse calculation libraries written strictly for iOS, running fully on-device. Local visibility is more rigorous too: topography, observer elevation, and the path band are included so results better match what you can actually see from your location. Eclipse search is free for ±5 years around today. The full historical and future range remains available with Eclipse Pro.
