Birth date: find your sign or possible range. Add an exact time and birthplace for a house when calculable.

## What this calculator returns

chiron calculator is a free natal Chiron placement tool. It calculates your Chiron sign, degree or degree range, and apparent motion. An exact, unambiguous birth time and a confirmed place can also provide a house. The accompanying reading is symbolic reflection, not a diagnosis or prediction.

## Start with what you know

Enter your birth date and choose Unknown, Approximate or Exact time. Unknown time checks a date interval instead of assuming noon. Approximate time keeps the selected tolerance. If the possible interval crosses a sign boundary, both candidates remain visible. Add birthplace to narrow the interval; add an exact time for a house.

## Check a different result

The zodiac is tropical and Placidus is the default house system. Whole Sign is available by explicit choice. Open Calculation to check the timezone and assumptions, or Position & houses to compare systems using the same details. A polar or cusp-boundary house can remain unavailable rather than being guessed.

## Keep your details local

Birth details are calculated in your browser, not uploaded to a chart, AI or geocoding API. Copy and Print summary exclude the original birth date, time, city, coordinates and timezone. Clear details removes the page’s input, result and restore snapshot; reloading does not restore it. Ordinary website requests still reach the hosting provider.

## Reading the placement

Start with the sign, then place that theme in the life area of your calculated house. The degree helps locate and verify the placement; it is not a personality score.

In astrology, Chiron is often called the “wounded healer.” Here that is a symbolic starting point for reflection—not evidence of a wound, diagnosis or event in your life.

## Use the calculator

[Open the real calculation workspace](https://chironcalculator.org/#birth-form). Three labelled examples are available in the interface: Birthday only, Known time & place, and Near a sign change. Examples are not personal results.

The calculation runs in the browser after explicit input. This public text contains no individual chart, birth record, inference about a visitor or API for submitting birth data.
