In tropical astrology, the zodiac is divided into twelve 30-degree segments, each associated with a sign. A person's sun sign is determined by the segment the Sun occupied at the moment of their birth. The Sun transits through the sign of Virgo approximately from August 23 to September 22 each year. As September 11 falls squarely within this period, any individual born on this date is designated a Virgo. This sign is an Earth element sign and is ruled by the planet Mercury.
Virgo is associated with traits such as meticulousness, practicality, analytical thinking, and a diligent nature. The influence of its ruling planet, Mercury, often imparts strong communication skills and a quick, logical mind. Consequently, individuals with this sun sign are often perceived as organized, service-oriented, and detail-focused. While the sun sign provides a general archetype, a complete astrological analysis requires a full natal chart, which considers the positions of the moon and other planets at the time of birth.
