Enter a date to find Chiron’s tropical sign and degree. Add time and coordinates for a Whole Sign house.
THE CALCULATION
One stated model.
This calculator calculates geocentric Chiron longitude with the tropical zodiac using a locally bundled Swiss Ephemeris model. The calculation runs in your browser; it does not send your birth data to a service or use a preset birth-date table.
With a birth time, UTC offset and coordinates, the page derives a Placidus ascendant and reports the corresponding Whole Sign house. The entire ascendant sign is house 1. A different zodiac or house system can produce a different label.
Range and uncertainty
Dates from 1 January 1800 through 31 December 2399 are accepted. Without a birth time, the result shows the range across your entered local calendar day and does not invent a house. If the range crosses a sign boundary, the sign is shown as Cannot determine.
A city label is not geocoded. For a house, enter both latitude and longitude yourself. The UTC offset is also entered manually, so historical daylight-saving rules are not inferred. Astrology is a symbolic interpretation system, not a scientific method of prediction.
USE THE RESULT WELL
Questions before interpretation.
Can I find my Chiron placement without a birth time?
Yes. Date and UTC offset return a sign and degree range for that local day. The house remains Cannot determine because it depends on the horizon at the birth moment.
What is my Chiron sign calculator showing?
It shows Chiron’s tropical zodiac longitude for your stated birth details. “Chiron placement calculator” and “what is my Chiron sign” describe the same result here.
Why might two Chiron calculators differ?
Check the date, clock time, historical UTC offset, tropical versus sidereal zodiac, and house system. A small time or offset difference matters most near a sign or house boundary.
What is my Chiron placement for?
Use this result as a chart label before reading an interpretation. For the rest of your chart, open the natal chart calculator.
After calculating the sign, read the Chiron in Aries natal guide or the Chiron in Taurus reflection guide for sign-specific questions.

When your result says Gemini, use the Chiron in Gemini guide to keep the sign, house, and a practical reflection separate.
If your result says Capricorn, read the Chiron in Capricorn guide for house-specific authority and achievement questions.
If your result says Sagittarius, read the Chiron in Sagittarius guide for natal meaning, all 12 house contexts, and a practical belief check.
If your result says Aquarius, read the Chiron in Aquarius guide for house contexts and a same-day belonging practice.
If your result says Scorpio, read the Chiron in Scorpio guide for all 12 house contexts and a boundary-aware trust-choice practice.
If your result says Leo, use the Chiron in Leo date guide to check the UTC boundary intervals before interpreting the placement.
If your chart places Chiron near the first-house boundary, read the Chiron in the 1st house guide for a reproducible two-time comparison.
