Terms of use
The short version: use The Birth Sky for reflection and enjoyment, not as professional advice.
Last updated 4 November 2026
What the site is for
The Birth Sky provides birth charts, numerology and related writing for reflection and entertainment. Nothing on the site is medical, psychological, legal or financial advice, and it should not be used to make decisions in those areas.
Accuracy
We work hard to calculate charts precisely, but a chart is only as accurate as the birth details you enter, and we cannot guarantee that the site is free of errors or always available.
Your use of the site
Please don't misuse the site: no automated scraping, no attempts to disrupt it, and no reselling of its content.
Our content
The text, design, illustrations and code of The Birth Sky belong to us or our licensors. You are welcome to share your own chart results for personal, non-commercial use. Constellation outlines are based on data from d3-celestial (BSD licence); place data is from GeoNames (CC BY 4.0).
