Natal tool

Chiron calculator

Enter a birth date. Add time and a selected city for the house. Switch Placidus and Whole Sign on the same result. Sign, exact degree, retrograde, and the next return print without a time.

Date alone still returns sign, exact degree, retrograde, and the next return. House needs a birth time and a selected city.

Placidus and Whole Sign can move the house — and a cusp sign. Toggle both on the same result.

Date alone returns sign, exact degree, Rx, and the next return. Add a birth time and pick a city if you want a house. Toggle Placidus and Whole Sign on the same result — a cusp can move.

You do not get a full chart, a synastry overlay engine, or a Swiss Ephemeris printout. Pro adds saved charts, a PDF, and transit windows to this natal degree — not a second engine.

Anonymous sample — not your chart

Limits of this engine

Positions are a Kepler orbit for 2060 Chiron plus a Meeus Earth model. House cusps can sit about a degree off a Swiss Ephemeris printout. High-latitude Placidus can fall back to Whole Sign; the result card says when that happened. Degree-as-age claims are folklore, not a computed age event. Method page.

Questions before you submit

What is my natal Chiron?

It is the geocentric longitude of 2060 Chiron at birth, shown here as sign, house, exact degree, and retrograde. Read the matching natal page after you calculate — do not treat the current sky as your placement.

Can I calculate Chiron without a birth time?

Yes. Date alone returns sign, exact degree, retrograde, and the next return window. House stays unknown until you add a time and a selected city with coordinates.

Why did my Chiron house change in Whole Sign?

Placidus and Whole Sign slice the sky differently. The same birth data can move Chiron across a house — and sometimes a sign — boundary. That is expected, not a bug.

Why is the house unknown?

No time, no coordinates, or a high-latitude Placidus failure. High-latitude Placidus can fall back to Whole Sign; the result card says when that happened.

Is this Swiss Ephemeris?

No. Positions are a Kepler orbit for 2060 Chiron plus a Meeus Earth model. House cusps can sit about a degree off a Swiss Ephemeris printout. We do not sell precision guarantees.

When is my Chiron return?

The date Chiron returns to this natal degree, in a ~50-year cycle. This tool reports the next date. Meaning lives on the return page — not a second calculator.

Does the Chiron degree equal my age of healing?

No. That is degree-as-age folklore, not a computed result. The number here is ecliptic longitude in the sign. The degree page labels the age story as optional.

Can I run synastry in this form?

No overlay engine. Calculate each natal Chiron separately, then read the synastry page for who feels the overlay.

Is the natal Chiron calculator free?

Yes. Natal sign, house, exact degree, retrograde, and the next return stay on this page. Pro is $9.90/mo for saved charts, a PDF, and the dates transiting Chiron hits this degree.

Is this medical or therapeutic advice?

No. Astrology software, not a diagnosis or a treatment plan. If you want a clinician, this page is the wrong tool.
