What Is My Zodiac Sign
The calculator above finds your zodiac sign from your date of birth. It also shows what to do if you were born on a cusp: the boundaries between signs shift by a day from year to year.
How it's calculated
Your sign is determined by the position of the Sun at the moment of birth. The Sun enters a new sign not on a fixed day but at the moment it reaches a certain ecliptic longitude, and that moment shifts by about six hours a year, then jumps back every four years because of the leap day.
So the boundary between Aries and Taurus can fall on April 19, 20 or 21, depending on the year and the time zone.
| Sign | Dates |
|---|---|
| Aries | March 21 – April 19 |
| Taurus | April 20 – May 20 |
| Gemini | May 21 – June 20 |
| Cancer | June 21 – July 22 |
| Leo | July 23 – August 22 |
| Virgo | August 23 – September 22 |
| Libra | September 23 – October 22 |
| Scorpio | October 23 – November 21 |
| Sagittarius | November 22 – December 21 |
| Capricorn | December 22 – January 19 |
| Aquarius | January 20 – February 18 |
| Pisces | February 19 – March 20 |
What the result means
Your Sun sign describes the core of your personality: will, direction, the way you show up in what matters. It is not the whole person: a birth chart also includes the sign of the Moon, the Ascendant and the positions of eight other planets.
Four elements: fire (Aries, Leo, Sagittarius) is action; earth (Taurus, Virgo, Capricorn) is practicality; air (Gemini, Libra, Aquarius) is thought and communication; water (Cancer, Scorpio, Pisces) is feeling.
Three modalities: cardinal signs (Aries, Cancer, Libra, Capricorn) initiate, fixed signs (Taurus, Leo, Scorpio, Aquarius) sustain, and mutable signs (Gemini, Virgo, Sagittarius, Pisces) adapt.
Born on the cusp
There is no such thing as being "on the cusp" in astrology: at any given moment the Sun is in exactly one sign. The in-between feeling comes from comparing yourself with table dates rather than with the Sun's actual position.
The calculator on this page works out the actual position of the Sun on your birthday rather than using table dates. If the Sun moved into another sign that day, it shows the time of the ingress: in that case the sign depends on the hour of birth. The exact position of the Sun for your date, time and place of birth is in the planet table of the Ascendant calculator.
Frequently asked questions
Is there a thirteenth sign, Ophiuchus?
The constellation Ophiuchus does cross the ecliptic. But Western astrology works not with constellations but with twelve equal sectors counted from the vernal equinox point, so by the way the system is built there can be no thirteenth sign.
Why doesn't my sign sound like me?
Most often because sign descriptions are generalizations, not a diagnosis. From the point of view of astrology itself, because the Sun is only one of ten points in the chart.
Does your sign affect your personality?
Tests don't confirm it. Large studies with big samples find no link between birth month and personality traits measured by standard questionnaires.
