Purpose of the tools

The tools calculate astronomical positions and present traditional astrological interpretations for education, entertainment and reflection. Astrology has not been established as a scientific method for predicting personality or events. Results are not medical, legal, financial or relationship advice.

Accuracy and responsibility

Check your input carefully. Historical time-zone records, uncertain birth times, geographic approximations and calculation conventions can affect results. We provide the tools as available and may correct or update them. Do not rely on a chart as the sole basis for an important decision.

Third-party materials

Open-source components, fonts and data retain their respective licenses and attribution requirements. Source acknowledgments do not imply that NASA, GeoNames or any library author endorses astrological interpretations or this website.
