What is a Birth Chart?

A birth chart (also called a natal chart or astrology chart) is a snapshot of the sky at the exact moment of your birth. It maps the positions of the Sun, Moon, and planets across the 12 zodiac signs and 12 astrological houses — creating a unique cosmic fingerprint that astrologers use to understand personality, life themes, and destiny.

PLANETARIUM's AI birth chart calculator uses precise astronomical calculations (Swiss Ephemeris) to generate your natal chart, then applies AI analysis to deliver a personalized, in-depth reading in plain language.

Birth Chart vs Chinese Astrology

Western astrology birth charts use the positions of planets at birth to analyze personality and life themes through a psychological lens. Chinese Bazi (Four Pillars) uses the Five Elements (Wu Xing) energy balance of the birth time to predict destiny. Zi Wei Dou Shu (Purple Star Astrology) maps 108 stars across 12 life palaces for granular fate analysis.

PLANETARIUM is one of very few platforms that combine all three traditions in a single AI-powered reading, giving you a holistic view of your cosmic blueprint from both Eastern and Western perspectives.
