Version guidance

Cite the exact package version when reproducibility matters. Use the current canonical website page for a general description of GetBirthChart. Record the chart schema, calculation profile, ephemeris data and timezone data alongside a software citation when those details affect your result. Include an access date for the website and mutable documentation pages.

The concept DOI resolves to the stable Zenodo project citation. For release-specific reproducibility, cite version 1.13.0 with the published version DOI 10.5281/zenodo.22206006. Do not infer that a DOI proves calculation correctness.

Release-aware citation checklist

For a coordinated release, verify the core tag, PyPI project page, GitHub Release and Zenodo version record. The web release should follow the package publish step so the public citation and install command point to the intended 1.13.0 release.
