About Vía Kármica

Vía Kármica brings together four traditions — Western astrology, Vedic astrology, the Chinese zodiac and numerology — in one free lucky chart. It started in Spain as a service of personalised astrology reports.

How we calculate

Planetary positions come from the open-source Astronomy Engine, checked against NASA/JPL Horizons. The calculation runs entirely in your browser: we never receive your birth data.

Our editorial principles

We describe what traditions say and where each item comes from. Stone symbolism is cultural: we never claim that a stone, color or number heals, cures or guarantees any result.
