About
SkyAndNumbers is a set of free astrology and numerology calculators made by EPE Tech Solutions, a small independent studio. Every calculator runs in your browser: your name, birth date, time and place are worked on by code on your own device and are never sent to us.
Astrology and numerology are traditions for reflection and entertainment. They are not science, and nothing on this site is a prediction, or health, money, legal or relationship advice. The readings are our own short summaries of what the traditions say, written for this site.
What we care about
Correct working. The sky positions, time zones and numerology sums behind each result are tested against independent sources before a page is allowed into search engines, and each result shows how it was calculated. The details are on How we calculate.

Test references, used only to check the code and never shipped: NASA JPL Horizons (public domain), the Hong Kong Observatory Gregorian-Lunar calendar conversion tables, Python zoneinfo, and the worked examples in Jean Meeus, Astronomical Algorithms (2nd edition, 1998). The lunar nodes, Black Moon Lilith, angles and houses are our own code from published formulas. We do not use Swiss Ephemeris.
How the site is paid for
It is free and has no ads, accounts or paid features today. If ads are added later, they will sit below the results, never between the form and the answer, and this page and the privacy page will say so first.
