Our sources
The schools these pages follow, named so you can check them.
Every tradition on this site has more than one school, and most sites quietly pick one and present it as the truth. These are ours, in the open. Where practitioners genuinely disagree, the page gives both readings rather than hiding the argument.
Astrology
Tropical zodiac and Placidus houses, the working standard of modern Western practice. Sign boundaries are computed from the Sun position for your birth moment, not read off a fixed calendar, which is why a cusp birthday can land differently here than in a magazine.
Tarot
Rider Waite Smith, first published in 1909, drawn by Pamela Colman Smith. Every card meaning follows that imagery, upright and reversed, and the artwork shown on the site is that same deck rather than a modern redraw.
Numerology
Pythagorean numerology, the Western letter-to-number system. Master numbers are given in both schools: the one that keeps 11, 22 and 33 whole, and the one that reduces them to 2, 4 and 6. Pages show both results, because both are in honest use.
Human design
The canon of the system as its founder published it, unchanged and unimproved: type, strategy, authority, profile, defined and open centres, channels and the sixty-four gates. Where the canon is silent, the page stays silent too.
Geography and time
GeoNames for city coordinates and time zones. A birth time is resolved to the right place and the right historical offset, including the daylight-saving rule in force on that date, because an hour of error moves a rising sign.
Astronomy
Planetary and lunar positions come from an astronomical engine and are checked against published JPL ephemerides. Figures are verified against ephemeris data rather than borrowed from another website, so a chart calculated here matches a chart calculated by professional software.
