In astrology, the Rising Sign, also called the Ascendant, is the zodiac Sign positioned on the eastern horizon at the moment and place of birth. Because the horizon changes continuously as Earth rotates, the Rising Sign depends on an accurate birth time and birth location. It forms one of the principal chart angles and is often associated with how a person approaches life, engages with the surrounding world, and is initially perceived by others. Its interpretation depends on the Sign involved, its ruling Planet, related Aspects, and the larger pattern of the Natal Chart. Within Zodiacology, the Rising Sign is read as one part of Your Zodiacal Configuration, not as a complete description of the person.
