Editorial interest 82/100 Selection signal · not a rating of the site

A technical astronomy site presenting tools and methods for computing apparent celestial positions, eclipses, and traditional Pañcāṅga quantities.

Landing page captured for the 2026-09-28 issue.

For: Astronomy and calendrical researchers, ephemeris developers, and Pañcāṅga readers
Worth noticing: The project reports about 64.4 million astronomical transitions across roughly 34,600 years, with O(log n) lookup.

Field notes

The page lays out a pipeline from JPL DE440/DE441 reference states through independent Rust SPK/DAF evaluation, apparent-position corrections, ecliptic conversion, and sidereal/Pañcāṅga calculations. It names its precession and nutation models and reports comparisons with jplephem, Skyfield, and xalen-time; those figures are project-stated benchmarks, not independently verified here.
