Understanding Your Zodiac Sign
Your zodiac sign, also known as your sun sign, is determined by the position of the sun at the time of your birth. In Western astrology, there are twelve zodiac signs, each associated with specific personality traits, strengths, weaknesses, and even elements (Fire, Earth, Air, Water).
These signs are derived from the twelve constellations that lie along the ecliptic, the apparent path of the sun across the sky over the course of a year. Each sign spans approximately 30 degrees of the ecliptic and corresponds to a specific period of the year.
The Twelve Western Zodiac Signs and Their Dates:
- Aries (The Ram): March 21 – April 19. Element: Fire.
- Taurus (The Bull): April 20 – May 20. Element: Earth.
- Gemini (The Twins): May 21 – June 20. Element: Air.
- Cancer (The Crab): June 21 – July 22. Element: Water.
- Leo (The Lion): July 23 – August 22. Element: Fire.
- Virgo (The Maiden): August 23 – September 22. Element: Earth.
- Libra (The Scales): September 23 – October 22. Element: Air.
- Scorpio (The Scorpion): October 23 – November 21. Element: Water.
- Sagittarius (The Archer): November 22 – December 21. Element: Fire.
- Capricorn (The Sea-Goat): December 22 – January 19. Element: Earth.
- Aquarius (The Water Bearer): January 20 – February 18. Element: Air.
- Pisces (The Fish): February 19 – March 20. Element: Water.
While your sun sign provides a foundational understanding of your core personality, a complete astrological chart considers the positions of all planets, the moon, and other celestial points at your exact time and place of birth. However, your sun sign remains a popular and accessible entry point into the world of astrology.
