"The day, month, year, time and place of birth are all needed to calculate a birth chart. Each natal chart includes the exact positions of the Sun, Moon, and the planets Mercury, Venus, Mars, Jupiter, Saturn, Chiron, Uranus, Neptune, and Pluto. Most astrologers include additional points such as the part of fortune, the lunar nodes, the vertex, some asteroids etc. These planets and additional points are then interpreted in regards to the Zodiac signs, the houses, and their various relationships with one another."
