Chiron in your chart: sign by birth date

Type the birth date and the tool shows the Chiron sign and whether it was retrograde. In the search tab you list every Chiron period in a sign, including the dips back before it settles in.

Why Chiron's sign has so many dates and reversals

Chiron (2060 Chiron) is an icy body between Saturn and Uranus that circles the Sun in about 50 years on a very eccentric orbit. Near perihelion (1996) it moves fast and stays only a year or so in Libra; near aphelion, in the signs of Pisces, Aries and Taurus, it moves slowly and stays 7 to 8 years in each. So the Chiron sign marks a wide generation in some cases (Pisces from 2011 to 2018, Aries from 2019 to 2026) and a short one in others (Libra, Virgo, Leo).
Because Chiron is retrograde for about five months a year, it crosses sign boundaries more than once. Chiron first entered Aries on April 17, 2018, went back to Pisces on September 26, 2018 and only settled into Aries on February 18, 2019. Anyone born between April 2018 and February 2019 has Aries or Pisces depending on the day, and using only "the date Chiron entered Aries" gets almost a year of births wrong. The tool's sign search lists every stretch, without hiding the reversals.
Chiron's calculations do not come from the same library as the planets, which does not include the body. The tool uses a table generated with the JPL Horizons API (object 2060, geocentric, ecliptic of date): one longitude every 10 days from 1900 to 2100, interpolated with a cubic. Tests compare ten independent Horizons values and the error stays below 0.03 degrees (under 2 arcminutes), far less than the distance between a position and a sign boundary in most cases. Outside 1900 to 2100, Chiron shows as unavailable. The reading ties the point to a wound and a gift of healing; it is symbolic tradition, not a diagnosis.

Full tool FAQ

How do I find my Venus sign without a birth time?

Venus spends 29 days in each sign on average, so on most days the date alone settles it. When Venus changes sign on your birth day, the tool shows the exact time of the change in the local time zone: those born before it have the earlier sign, those born after have the new one. Without a time, it lists both possibilities. With the time and the city, the result is fixed.

Frequently asked questions

What is the Chiron sign for someone born in 2000?

Chiron was in Sagittarius until December 11, 2001 (with a visit to Scorpio between June 1 and September 22, 1999), so anyone born in 2000 has Chiron in Sagittarius. In 2001 the change to Capricorn fell on December 11.

Why is Chiron different from the planets in the tool?

Because the ephemeris library for the planets does not include Chiron. It comes from a JPL Horizons table loaded only when needed, which is why a brief loading message appears on the first lookup.

Is Chiron a planet, asteroid or comet?

It is cataloged as a minor planet and centaur, with asteroid and comet traits. Astrology only cares about its position on the ecliptic, which is what the tool calculates; the astronomical classification does not change the sign.

Can I look up Chiron before 1900?

Not in this tool: the table covers 1900 to 2100 and outside it Chiron shows as unavailable. The limit exists to keep the error below 0.03 degrees, which was validated against Horizons.
