Your zodiac sun sign is determined by the position of the Sun at the moment of your birth. It represents your core identity, ego, and life purpose. There are 12 sun signs, each spanning roughly 30 days of the calendar year, from Aries through Pisces.
The 12 signs are: Aries (Mar 21–Apr 19), Taurus (Apr 20–May 20), Gemini (May 21–Jun 20), Cancer (Jun 21–Jul 22), Leo (Jul 23–Aug 22), Virgo (Aug 23–Sep 22), Libra (Sep 23–Oct 22), Scorpio (Oct 23–Nov 21), Sagittarius (Nov 22–Dec 21), Capricorn (Dec 22–Jan 19), Aquarius (Jan 20–Feb 18), and Pisces (Feb 19–Mar 20).
The four elements are Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), and Water (Cancer, Scorpio, Pisces). Your element reflects your temperament and fundamental approach to life — Fire signs tend to be passionate, Earth signs grounded, Air signs intellectual, and Water signs emotionally intuitive.
Modality (also called quality) describes how a sign operates within its season. Cardinal signs (Aries, Cancer, Libra, Capricorn) initiate and lead. Fixed signs (Taurus, Leo, Scorpio, Aquarius) are determined and persistent. Mutable signs (Gemini, Virgo, Sagittarius, Pisces) are adaptable and flexible.
Your sun sign reflects your core personality and identity. Your moon sign, determined by the Moon's position at birth, governs your emotions and inner world. Your rising sign (ascendant) is the zodiac sign that was on the eastern horizon when you were born and represents how others perceive you. Together these three form your 'Big Three' in astrology.
A birth date is sufficient to determine your sun sign in almost all cases. The only exception is if you were born on a cusp day — the first or last day of a sign's range — where the Sun may have shifted signs depending on the exact time and location of birth. For absolute precision on cusp birthdays, knowing your birth time and location is recommended.
Being born 'on the cusp' means your birthday falls within a day or two of the transition between two zodiac signs. While traditional astrology assigns you to one sign only, some astrologers believe cusp individuals may exhibit traits of both neighboring signs. Use your exact birth time for a definitive answer if you're near a sign boundary.
Your sun sign based on the tropical zodiac (used in Western astrology) does not change — it is fixed by the calendar date of your birth. However, the sidereal zodiac used in Vedic astrology shifts over centuries due to the precession of Earth's axis, which means your Vedic sign may differ from your Western sun sign by about one sign.
