The Sun sign is the zodiac sign the Sun was in at the time of your birth.
It represents your core personality, ego, and life purpose—the traits you consciously project to the world.
The Sun sign is the most commonly known sign and is determined solely by your date of birth (e.g., Aries, Taurus, Gemini).

An Example:
If your Sun sign is Leo, you might have a bold and confident outward personality. But if your Moon sign is Pisces, you may have a sensitive and intuitive inner world that isn’t immediately obvious to others.
Together, the Moon and Sun signs (along with the Rising/Ascendant sign) provide a more complete picture of your astrological personality.
