The Zodiac Signs (also called Sun Signs or Star Signs) are the foundation of Western astrology. Your zodiac sign is determined by the position of the Sun at the moment of your birth and represents your core identity, ego, and life purpose. While the Sun sign is just one piece of your complete birth chart, it's the most well-known and influential astrological placement.
In this comprehensive guide, you'll discover everything about all 12 zodiac signs: their dates, personality traits, strengths, weaknesses, compatibility with other signs, and much more.

What is a Zodiac Sign?
The zodiac is a belt of the sky divided into 12 equal sections of 30° each, through which the Sun, Moon, and planets appear to travel. Your Sun sign (commonly called your "zodiac sign") indicates which of these 12 sections the Sun occupied at your birth.
The word "zodiac" comes from the Greek zōidiakos, meaning "circle of animals," as most constellations in this belt are represented by animals or mythological creatures.
Why Your Sun Sign Matters
- ☀️ Core Identity: Represents who you are at your essence
- 🎯 Life Purpose: Indicates your fundamental goals and drives
- 💪 Vitality: Shows how you express your energy
- 👤 Ego: Defines your sense of self and pride
- 🌟 Creativity: Reflects your creative expression
Important: While your Sun sign is significant, a complete astrological profile requires your Moon sign (emotions), Rising sign (outer personality), and the positions of all planets. This creates your unique birth chart.

Born on the Cusp?
If you're born on a "cusp" (when the Sun changes signs), you need your exact birth time to know your true sign. The Sun doesn't change signs at midnight—it varies each year. Our calculator uses Swiss Ephemeris data for accurate determination.
Note: There's no such thing as being "two signs." You're one sign or the other—though the sign the Sun was approaching may influence you slightly.
