It's really simple: A horoscope is an astrological chart that's calculated based upon the date, time, and place of birth. A chart also can be calculated for an occasion, an issue, and even a country! Symbols are wont to represent planets, signs, and geometric connections called aspects. In most cases, the horoscope in Western astrology is drawn on a circular wheel. The astrologer studies your chart and analyzes the patterns and factors which describe your personality and wishes. during a sense, an astrologer is 'reading' the knowledge contained in your chart.
