What does your Sun sign represent in astrology?

Your Sun sign represents your core ego, conscious identity, willpower, and the primary life energy guiding your purpose.

What if I was born on the cusp of two zodiac signs?

The Sun transitions into a new sign at a precise moment each year. Entering your exact birth time will determine your true Sun sign.

How many zodiac signs are there, and how are they ordered?

There are 12 zodiac signs, each corresponding to roughly one month: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces, in that order through the year.

Why do sign date ranges shift slightly from year to year?

The exact moment the Sun crosses into a new sign varies by a day or so each year due to the mismatch between the 365.25-day solar year and the calendar, plus the slow astronomical effect of axial precession — which is why cusp dates aren't perfectly fixed.
