What is a natal chart?
A natal chart (also called a birth chart or horoscope) is a map of the sky at the exact moment and place of a person's birth. Rooted in Hellenistic astrology (Ptolemy, ~150 CE), it plots the positions of the Sun, Moon, and planets across 12 zodiac signs and 12 houses. The chart reveals personality traits, emotional patterns, communication style, relationship tendencies, career aptitudes, and life challenges. Modern natal astrology also considers outer planets (Uranus, Neptune, Pluto), lunar nodes (Rahu and Ketu), Lilith (Black Moon), and Chiron — each adding layers of psychological and karmic interpretation.
How does Book of Life calculate a natal chart?
Book of Life uses the Swiss Ephemeris — the same astronomical library trusted by professional astrologers worldwide — to compute planetary positions to arc-second precision. The input requires birth date, exact birth time, and birth place (geocoded to latitude, longitude, and timezone). The engine calculates: all 10 classical and modern planetary positions, the Ascendant and Midheaven (MC), 12 house cusps (Placidus system by default), lunar nodes (true node), Lilith, and Chiron. It then computes all major aspects (conjunction, opposition, trine, square, sextile) between chart points.
What does the natal report include?
The natal section of Book of Life contains 14 sub-readings, each 180–260 words of dense personal interpretation: Sun sign, Moon sign, Ascendant, MC (career and public image), Mercury (communication), Venus (love and values), Mars (drive and conflict), Jupiter (expansion), Saturn (structure and karma), Uranus (innovation and disruption), Neptune (intuition and illusion), Pluto (transformation), Rahu & Ketu (karmic axis and life purpose), and Lilith (shadow femininity). Each sub-reading begins with a brief explanation for the beginner, then delivers a deep interpretation for the experienced, and concludes with a concrete actionable insight drawn from the person's specific placement.
