What a birth chart is
A birth chart is a snapshot of the sky at the moment you were born: the exact positions of the Sun, Moon and eight planets relative to the point where you arrived. Astrology reads this configuration as a personal coordinate system — strengths, recurring scenarios, the areas where energy flows easily and the ones that ask for practice.
The chart has three layers. Planets answer "what acts": the Sun is will, the Moon is feeling, Mercury is thinking, Venus is love and values, Mars is action. Signs show how that energy is colored: Mars in Aries acts directly, Mars in Libra negotiates. Houses answer "where": career, family, money, relationships — twelve life arenas. The full reading connects all three layers, and that's exactly what the AI in Astro Orb does for your specific chart.
FAQ
+How is the chart calculated?
Right in your browser using the astronomy-engine library (JPL-level precision for planetary positions). Nothing is sent to a server — the result appears instantly.
+Why does the birth time matter?
The ascendant moves through the whole zodiac every 24 hours — about one sign every two hours. Without a time we show planets in signs; with a time you also get the ascendant, and the Mini App adds the full house grid.
