Natal Chart

Tropical geocentric ecliptic longitudes for the Sun, Moon and planets, computed on this page from the same AstroAlgos periodic terms (Meeus / VSOP) used in the 3D views. If you give a latitude and longitude, a tropical ascendant, Midheaven and whole-sign houses are added. Distances are not used.

Birth data

Time is UTC (same convention as the engine Julian Day). Leave the time empty to use 12:00 UTC. If you only know a local clock time, convert it first (example: UTC+2 means subtract 2 hours).

Place can be empty: the wheel then shows planets in signs only. Ascendant, Midheaven and houses need both latitude and longitude.
