About the zodiac sign calculator
This calculator determines your Western (tropical) zodiac sign from your date of birth. Only the day and month matter — the year does not affect the sign. The result is computed instantly in your browser.
The zodiac is divided into 12 signs, each tied to one of four elements — Fire, Earth, Air or Water — and to a ruling planet. These links form the basis of classical astrology and personality descriptions.
Below the result you'll find a table of all 12 signs with their exact start and end dates. It's handy for checking the signs of friends and family or clarifying the cusp days where two signs meet.

Frequently asked questions
How do I find my zodiac sign?
Pick your date of birth in the field above and the calculator instantly shows your zodiac sign, its element and ruling planet. Only the day and month matter; the year can be anything.
Does the birth year affect the zodiac sign?
No. The Western zodiac sign depends only on the day and month of birth. The year matters for the Eastern (Chinese) zodiac, but not for the star sign.
What if I was born on the cusp of two signs?
People born on the first or last day of a sign's period are said to be born 'on the cusp.' The exact sign then depends on the year and time of birth; the calculator shows the sign based on the standard calendar dates.
What is a zodiac element?
Each sign belongs to one of four elements: Fire, Earth, Air or Water. The element reflects temperament and core character traits and is often used when assessing compatibility.
What does the ruling planet mean?
The ruling planet is the celestial body that, in astrology, governs a sign and gives it characteristic qualities — for example, Mars rules Aries, and Venus rules Taurus and Libra.
Are the zodiac sign dates accurate?
The calculator uses the commonly accepted tropical zodiac dates. In some years the boundary between signs can shift by a day due to the Sun's actual position, so on cusp days the result may differ by one day.
