benchmark_equinox_validation¶

Benchmark Badí‘ Calendar equinox JDs against NASA/JPL ephemerides via Skyfield.

contrib.misc.benchmark_equinox_validation.badidatetime_equinox_jd(year, coords=(51.477928, -0.001545, 0))[source]¶: Compute your package’s vernal equinox JD (or Naw-Rúz anchor) using your coefficient-based algorithm.

contrib.misc.benchmark_equinox_validation.jpl_vernal_equinox_jd(year, eph)[source]¶: Compute the JD of the vernal equinox (geocentric apparent Sun) using the JPL DE ephemeris (TT-based JD).
