A horoscope is an astrological chart or diagram representing the positions of the Sun, Moon, planets, astrological aspects and sensitive angles at the time of an event, such as the moment of a person's birth.
Horoscope often refers to an astrologer's interpretation, usually based on a system of solar Sun sign astrology; based strictly on the position of the Sun at the time of birth, or on the calendar significance of an event.
In Hindu astrology, birth charts are called kuṇḍali which are very significant and are based on movement of stars and moon. Auspicious events and rituals are started after checking the kuṇḍali of a person including the marriage in which the birth charts of the boy and girl are matched.
