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.
The word horoscope is derived
from Greek words hõra and
scopos meaning "time" and "observer"
(horoskopos, pl. horoskopoi, or "marker(s) of the hour").
