What Is a Zodiac Sign?
A zodiac sign, also known as a sun sign or star sign, is one of twelve 30-degree sectors of the celestial longitude that the Sun passes through during the year. Each zodiac sign corresponds to a constellation and is associated with specific personality traits, behaviors, and characteristics in Western astrology.
Your zodiac sign is determined by the position of the Sun at the exact moment of your birth. This system originated in Babylonian astronomy over 2,400 years ago and has been refined through Greek, Roman, and modern Western astrological traditions.
The 12 Zodiac Signs
Here are all twelve zodiac signs with their date ranges and symbols:
The Four Elements
Each zodiac sign is associated with one of four classical elements, which influence the sign's fundamental nature:
- Fire Signs (Aries, Leo, Sagittarius): Passionate, dynamic, energetic, and temperamental. Fire signs are natural leaders who inspire others.
- Earth Signs (Taurus, Virgo, Capricorn): Grounded, practical, reliable, and materialistic. Earth signs value stability and work hard for their goals.
- Air Signs (Gemini, Libra, Aquarius): Intellectual, communicative, social, and analytical. Air signs love ideas, relationships, and mental stimulation.
- Water Signs (Cancer, Scorpio, Pisces): Intuitive, emotional, sensitive, and mysterious. Water signs are deeply connected to their feelings and intuition.
The Three Modalities
Besides elements, each sign has a modality (or quality) that describes how it expresses its energy:
- Cardinal Signs (Aries, Cancer, Libra, Capricorn): Initiative, leadership, action-oriented. Cardinal signs start new projects and lead the way.
- Fixed Signs (Taurus, Leo, Scorpio, Aquarius): Determination, persistence, stability. Fixed signs see things through to completion.
- Mutable Signs (Gemini, Virgo, Sagittarius, Pisces): Flexibility, adaptability, change. Mutable signs are versatile and embrace transformation.
What Are Cusp Signs?
If you were born on a date that falls on the boundary between two zodiac signs (typically within 2-3 days of the transition), you may be born "on the cusp." While the Sun is technically only in one sign at any given moment, those born on cusps often exhibit characteristics of both signs.
Frequently Asked Questions
Your zodiac sign is determined by the position of the Sun relative to the constellations at the time of your birth. Each of the 12 zodiac signs occupies a 30-degree segment of the 360-degree zodiac circle, with each sign lasting approximately one month.
Your sun sign (what this calculator shows) represents your core identity, ego, and conscious self. Your moon sign represents your emotional nature, inner self, and subconscious. Your moon sign is calculated based on the Moon's position at your exact birth time and location.
Zodiac date ranges can vary by 1-2 days depending on the year, because the Sun doesn't enter each sign at exactly the same time every year (due to leap years and Earth's elliptical orbit). The dates shown here are the most commonly used ranges in Western astrology.
If born within 2-3 days of a sign transition, you may identify with traits of both signs. However, technically your sun is only in one sign at any given moment. To know your exact sign, you would need to check an ephemeris for your specific birth year, or consult an astrologer with your exact birth time.
Yes, they are completely different systems. Western astrology uses 12 monthly signs based on the Sun's position. Chinese astrology uses 12 yearly signs based on the lunar calendar, with each sign corresponding to an animal. Both have separate elements and compatibility systems.
