星占い, or astrology, is the study of celestial bodies' positions and movements to gain insights into human affairs and natural phenomena. It is based on the belief that the alignment of planets and stars at the time of a person's birth can influence their personality and life events. In 日本, 星占い is popular in various forms, including daily horoscopes found in newspapers and magazines. Many people consult their zodiac signs, which are determined by their birth dates, to understand their traits and predict future happenings.
