Find your Sun sign from your birth date in a moment. This calculator works out the real position of the Sun on the day you were born and returns your Western zodiac sign, along with its element, ruling planet and the traits the sign is known for. Because it uses the actual solar position, births on a cusp date are resolved correctly.
What Your Sun Sign Means
The Sun sign is the heart of a horoscope and the one most people know. It describes your core self, your basic identity and the direction of your conscious will, which is why daily horoscopes are written for it. The Sun spends about a month in each of the twelve signs, so your birth date alone is enough to find it for almost everyone.
Why the Cusp Is Handled Correctly
The dates that separate the signs shift slightly from year to year, so a simple date table can place a cusp birthday in the wrong sign. This tool avoids that by computing where the Sun actually was at your birth, rather than looking the date up in a fixed list. If you were born within a day of a sign change, adding your birth time makes the answer exact.
Beyond the Sun Sign
Your Sun sign is only part of the picture. The Moon sign describes your inner emotional self and the Rising sign the face you show the world, and a full birth chart places every planet in a sign and house. If the Sun sign description only half fits, that is usually because the rest of your chart fills in the detail, which the other tools here can show.
Finding Your Sun Sign
Enter your date of birth and press Calculate. Most birthdays return a clear Sun sign from the date alone, but if you were born on the day the Sun changed signs, adding your birth time and timezone settles it. The result names your tropical Sun sign with its element, ruling planet and the qualities the sign is commonly linked with.
Tropical Signs and the Seasons
The Western Sun sign is tied to the seasons rather than the constellations. Aries begins at the spring equinox, and the signs follow the turning year from there, which is the tropical system used across Western astrology. Because of a slow shift called precession, this no longer lines up with where the Sun actually sits among the background stars, so your tropical sign can differ from the constellation the Sun is really in, and from a Vedic sidereal reading.
A Starting Point, Not the Whole You
Your Sun sign is the most famous part of a chart, but it's one piece of it. The Moon, the Rising sign and the placements of the other planets fill in a far more individual picture, which is why two people of the same sign can feel so different. Read the Sun sign as the headline and the rest of the chart as the story underneath it.
Sun Sign Questions
What is my Sun sign?
Your Sun sign is the zodiac sign the Sun was passing through when you were born. Enter your birth date and the calculator finds it from the real solar position, along with its element and ruling planet.
What if I was born on a cusp?
Because the calculator uses the actual position of the Sun rather than a fixed date table, cusp births are resolved correctly. Adding your birth time makes the result exact if you were born within hours of a sign change.
Is the Sun sign the same as the star sign?
Yes. Star sign is just another name for the Sun sign, the sign the Sun occupied at birth. It is the sign used for popular daily and monthly horoscopes.
Positions are computed with the Swiss Ephemeris. Astrological interpretations are traditional and are offered for reflection, not as guaranteed predictions.
