In the context of astrology, the ascendant—often referred to as the rising sign—is the specific zodiac sign that was ascending over the eastern horizon at the exact moment of an individual's birth.1

Astrologers interpret this point as a significant factor in a person's life. They believe that the constellation and celestial objects positioned at this specific point on the eastern horizon at the time of birth exert a lifelong, controlling influence over the individual. While modern usage of the term "ascendancy" has moved away from these mystical connotations, within the practice of divination, the ascendant remains a foundational element used to describe the circumstances of one's "earthly debut" and is considered a key component of a birth chart.21
