Method

This page is the method note for the calculator, not a meaning essay. For natal interpretation start at What is Chiron. To run the numbers use the Chiron calculator.

What we compute

The tool reports natal 2060 Chiron as sign, optional house, exact degree, retrograde, and the next return date. That is the whole engine. There is no full chart, no synastry engine, no Lilith, no Human Design.

Ephemeris

Positions come from JPL-style Keplerian elements for 2060 Chiron at epoch J2000, integrated with standard Meeus-style solar/sidereal machinery in this app. This is not Swiss Ephemeris. Do not cite Swiss Eph precision, arc-second guarantees, or a licensed JPL SPK kernel. For most natal questions the sign, house, and degree-to-the-arcminute are the useful output; if you need a professional ephemeris, compare with one.

Houses

You can switch Placidus and Whole Sign on the same result. House cusps are a model, not a measurement. At high latitudes Placidus can fail to build cusps; the calculator then falls back to Whole Sign and says so on the result card. Missing birth time or coordinates leave the house unknown. Degree-as-age folklore is not a computed event.

Birth data

Date is required. Time and a selected city unlock the house. Location search uses Open-Meteo geocoding through our proxy. Inputs are used to compute that request; we do not sell charts. Privacy detail is on the Privacy Policy.

What this is not

Interpretations on this site are astrological, not medical, psychological, or legal advice. We do not offer human readings. Visible FAQ copy on a page is not a Google FAQ rich result.

Changelog of the method

If the integrator, element set, or house fallback changes, this page should change with it. The date above is the last editorial update.
