Frequently asked questions
What is a sun sign?
Your sun sign is determined by the position of the Sun in the zodiac on your birth date. It is the most widely known placement in Western astrology and represents your core identity, ego, and life purpose.
Why do some sources give different date ranges for each sign?
The Sun moves into each zodiac sign on a slightly different date each year due to the way the Gregorian calendar aligns with the solar year. People born on the first or last day of a sign's range are called "cusps" — for precision, a full birth chart using exact time and location is recommended.
Is my sun sign the same as my star sign?
Yes — "sun sign" and "star sign" refer to the same thing in Western astrology. Both describe the zodiac constellation the Sun occupied at the time of your birth.

The 12 Western zodiac signs explained
Western astrology divides the ecliptic into 12 equal segments, each associated with a zodiac constellation. The signs are grouped by element (Fire: Aries, Leo, Sagittarius; Earth: Taurus, Virgo, Capricorn; Air: Gemini, Libra, Aquarius; Water: Cancer, Scorpio, Pisces) and by quality (Cardinal, Fixed, Mutable). Your sun sign reflects which segment the Sun occupied at the moment you were born.
What your sun sign reveals about you
In Western astrology, the sun sign is considered the most significant placement because the Sun represents vitality, ego, and core identity. However, a complete astrological profile includes the moon sign (emotions), rising sign (outward persona), and the positions of other planets. Your sun sign is the starting point — a foundational description of your personality archetype that many people find surprisingly accurate.
