About Zodiac Signs
Zodiac signs are part of Western astrology, a system that divides the year into 12 periods based on the position of the sun relative to constellations. Your zodiac sign, also called your sun sign or star sign, is determined by your birth date.
The Four Elements
Each zodiac sign belongs to one of four elements, which influence personality and temperament:
- Fire (Aries, Leo, Sagittarius): Passionate, energetic, enthusiastic, and action-oriented. Fire signs are natural leaders who inspire others.
- Earth (Taurus, Virgo, Capricorn): Practical, grounded, reliable, and focused on material security. Earth signs value stability and hard work.
- Air (Gemini, Libra, Aquarius): Intellectual, communicative, social, and idea-driven. Air signs thrive on mental stimulation and connection.
- Water (Cancer, Scorpio, Pisces): Emotional, intuitive, empathetic, and deeply feeling. Water signs are sensitive to their environment and others' emotions.
The Three Modalities
Modalities describe how each sign approaches life and initiates change:
- Cardinal (Aries, Cancer, Libra, Capricorn): Initiators who start new projects and lead change. Cardinal signs mark the beginning of each season.
- Fixed (Taurus, Leo, Scorpio, Aquarius): Stabilizers who maintain momentum and resist change. Fixed signs occur in the middle of each season.
- Mutable (Gemini, Virgo, Sagittarius, Pisces): Adapters who embrace change and transition. Mutable signs close out each season.
Ruling Planets
Each zodiac sign is governed by a ruling planet that influences its core characteristics. For example, Mars rules Aries and brings assertiveness and drive, while Venus rules Taurus and Libra, emphasizing love, beauty, and harmony.
Zodiac Sign Calculator FAQ
What is a zodiac sign?
A zodiac sign, also called a sun sign or star sign, is one of 12 astrological signs determined by your birth date. It represents the position of the sun at the time of your birth and is believed to influence your personality, behavior, and life path. The 12 signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.
How do I find my zodiac sign?
Your zodiac sign is determined by your birth date. Enter your birth month and day in the calculator above to instantly find your sign. Each sign covers approximately 30 days, starting with Aries (March 21 - April 19) and ending with Pisces (February 19 - March 20).
What if I was born on a cusp?
If you were born on the day a zodiac sign changes (called a cusp), your sun sign is determined by the exact time and location of your birth. Most cusp dates occur on the 20th-23rd of the month. This calculator uses the standard date ranges, but you may want to check your birth chart for precise accuracy if you were born on a cusp day.
What is the difference between sun sign, moon sign, and rising sign?
Your sun sign is your main zodiac sign based on your birth date. Your moon sign is determined by the position of the moon at birth and represents your emotions and inner self. Your rising sign (ascendant) is based on the constellation rising on the eastern horizon at your birth time and reflects how others see you. This calculator shows your sun sign only.
Are zodiac signs accurate?
Astrology is not a science and is not supported by empirical evidence. Whether zodiac signs accurately describe personality is a matter of personal belief. Many people find astrological descriptions resonant and use them for self-reflection, while others view them as entertainment. This tool is for informational and entertainment purposes.
What does element mean in astrology?
Each zodiac sign belongs to one of four elements: Fire, Earth, Air, or Water. Fire signs (Aries, Leo, Sagittarius) are energetic and passionate. Earth signs (Taurus, Virgo, Capricorn) are practical and grounded. Air signs (Gemini, Libra, Aquarius) are intellectual and communicative. Water signs (Cancer, Scorpio, Pisces) are emotional and intuitive.
What does modality mean in astrology?
Modality (also called quality) describes how a sign approaches change and action. Cardinal signs (Aries, Cancer, Libra, Capricorn) initiate and lead. Fixed signs (Taurus, Leo, Scorpio, Aquarius) stabilize and resist change. Mutable signs (Gemini, Virgo, Sagittarius, Pisces) adapt and transition easily.
What is a ruling planet?
Each zodiac sign is governed by a ruling planet that influences its core traits. For example, Mars rules Aries (energy, assertiveness), Venus rules Taurus and Libra (love, beauty), Mercury rules Gemini and Virgo (communication, intellect), and so on. The ruling planet adds depth to understanding each sign's characteristics.
Can I have traits from other zodiac signs?
Yes. Your sun sign is just one part of your astrological profile. You have a full birth chart that includes moon signs, rising signs, and planetary placements, which can give you traits from multiple signs. Additionally, people near cusp dates may exhibit traits from neighboring signs.
What are the best zodiac sign matches?
Compatibility in astrology is complex and depends on entire birth charts, not just sun signs. Generally, signs of the same element (Fire with Fire, Earth with Earth, etc.) or complementary elements (Fire with Air, Earth with Water) are considered compatible. However, any sign pairing can work with understanding and effort.
