Natal Chart
Definition
A map of the sky at the exact moment and place you were born — the positions of the sun, moon, and planets across the zodiac signs and houses — and the foundation of personal astrology.
A natal chart — also called a birth chart — is a map of the sky at the exact moment and place you were born: the positions of the sun, moon, and planets across the twelve zodiac signs and houses.
It’s the foundation of personal astrology, and what separates a real reading from a generic sun-sign horoscope. A natal chart is computed from precise ephemeris data using your birth date, time, and location, so accuracy depends on knowing your birth time. Everything else in astrology is read against it — your character from the chart itself, and your timing from the transits that move across it.
Because it’s personal to you, the natal chart is also what lets an AI mystic companion give guidance specific to your life rather than one of twelve templates.
