Eclipses

Explore eclipses by Hebrew year, observer circumstances, eclipse geography and Eretz Yisrael visibility estimates, with catalogue and computed sources distinguished.

Explore solar and lunar eclipses, shadow geometry, geographic paths and local circumstances. Catalogue entries use Fred Espenak and Jean Meeus’s NASA GSFC Five Millennium Catalogues; computed searches extend exploration beyond catalogue coverage.

Eretz Yisrael visibility badges are regional sampling estimates. Ancient and distant-future timings and ground paths are uncertain, especially through ΔT. Computed events are research estimates, not historical confirmation.

Jewish Cosmology is an interactive research and educational web application connecting Hebrew dates, traditional Jewish calendar calculations and halachic concepts of time with the observable motions of the Sun, Moon and planets, astronomical seasons and eclipses.

JavaScript is required for the interactive explorers and calculations. The descriptions and navigation remain available without JavaScript.
