Accurate astronomical calculation
A complete birth chart, made understandable.
Enter the local date, recorded time, and birthplace of birth. We calculate the chart first, then explain it layer by layer.
What this calculator uses
Unlike a date-only horoscope lookup, a natal chart uses an exact UTC instant plus birthplace latitude and longitude. This is what makes the Moon degree, Ascendant, Midheaven, and houses personal to the moment.
Your result includes ten core planets, Chiron and the North Node, the twelve Placidus cusps, planets in houses, and five major aspect types with configurable orbs.
All positions use the tropical zodiac. When time is known, houses use the Placidus system. Calculations are deterministic; no AI is used to produce astronomical coordinates.
