Chiron Sign Calculator

Enter your birthday to find your Chiron sign, down to the degree, and the dates of your Chiron return.

Your Chiron sign is the zodiac sign that the small body Chiron was in when you were born. Astrologers call Chiron the wounded healer. They read its sign as a deep, early hurt and, in time, the place where you are best able to help others. Everyone born within a few years of you shares your Chiron sign. To find it, you only need your date of birth.

How the calculator works

Chiron is a real object, about 200 kilometres across, that orbits the Sun between Saturn and Uranus. Charles Kowal found it on photographs taken at Palomar Observatory in 1977. It was the first of a class now called centaurs, and it sometimes grows a faint cloud of gas like a comet, so astronomers list it as both an asteroid and a comet.

The astronomy library behind this site covers the planets but not Chiron, so we worked its orbit out ourselves. We start from positions published by NASA's Jet Propulsion Laboratory, one every 20 years, and calculate the path between them under the pull of the Sun and the eight planets. Against NASA's own figures for where Chiron appears from Earth, the largest gap across 11 dates from 1930 to 2040 is 0.4 arcseconds, about 0.0001 of a degree. The comparison is on the method page.

Why Chiron spends years in some signs and months in others

Chiron's orbit is a stretched oval. At its closest it comes inside the orbit of Saturn, and at its farthest it reaches nearly to Uranus. It moves quickly at the near end and crawls at the far end. One lap takes 50.0 years, but the time is shared out very unevenly.

So a Chiron in Aries generation covers about 8 birth years, and a Chiron in Virgo generation fewer than 2.

Chiron retrograde

Chiron is retrograde once a year, for 128 to 157 days at a stretch, which is 39% of the time. About two people in five are born with it, so astrologers give it little weight on its own. Its practical effect is on the dates: Chiron usually enters a new sign, backs out of it for a few months, then goes in to stay. You can see the pattern in the table of dates.

The Chiron return

Around your 50th birthday, Chiron comes back to the place it held when you were born. Astrologers treat the Chiron return as a turning point of midlife: old hurts come up to be dealt with, and experience starts to count as something to pass on.

We worked out the return for three birthdays in every year from 1930 to 2040, 333 in all. The first exact date fell between ages 49.2 and 50.9. Because of the yearly retrograde, Chiron crosses the birth degree three times in 71% of cases, once in 24% and five times in 5%, spread over as much as two years.

A worked example

Take someone born on March 10, 1976. Chiron was at 25°27′ Aries that day, moving forward. It had been in Aries without a break since January 30, 1969 and left on May 28, 1976. The Chiron return came in three passes: May 27, 2025, October 4, 2025 and March 27, 2026, starting at age 49.

Someone born on June 15, 1995 has Chiron at 20°43′ Virgo. Chiron was near the fast end of its orbit then, and it stayed in Virgo only from September 3, 1993 to September 9, 1995. That return begins on August 19, 2045.

What each Chiron sign means

Chiron has been used in astrology only since its discovery in 1977. It is named after the centaur of Greek myth who taught heroes and healers, and who was struck by a poisoned arrow that left a wound he could not cure in himself. The readings follow that story: a wound, and the skill that grows from living with it.
