The eclipse catalogue we wished existed
NASA's eclipse catalogue, put together by Fred Espenak, is the gold standard - and it covers about 5,000 years. Wonderful for most purposes, but if you want to know which eclipses were visible from your village in 1320 BCE, or model what's coming in 13,000 CE, the catalogue runs out.
EclipseDB extends that range. It computes 30,000 years of eclipses (15,000 in each direction from now) using JPL's DE441 ephemeris, and lets you search by location or date - all in your browser, no signup.

Who uses it
Researchers, students, sky-chasers
EclipseDB is used by historians cross-checking eclipse references in old texts, students writing astronomy papers, and eclipse chasers planning trips a decade out. We also expose an API that takes a lat/lon and returns the eclipses visible from there over any 200-year window - currently powering our companion app at astronomyapps.com.
Our eclipse-computation framework behind EclipseDB is published as an open paper on Zenodo: zenodo.org/records/19319453. A research contribution by Anish Kumar PV, founder of RiSa Astronomy.
