Astrologer Ephemeris & Research Tools

For research work: generate an ephemeris table for any date range, step, and set of bodies, and plot a graphic ephemeris to see aspect patterns form across years.

Custom ephemeris tables

Generate a table for any date range and step — daily, weekly, monthly — across whichever bodies you need, including asteroids, centaurs, and hypotheticals alongside the traditional set. Output can be exported for use outside the app. This is the tool for checking a claim against the actual positions rather than trusting a summary.

Graphic ephemeris

A graphic ephemeris plots positions as lines across time so aspect patterns become visible as crossings. Configurations that are invisible in a table — a slow triple conjunction forming over three years, a repeating square that tightens each pass — read immediately as shapes. This is how research questions about long periods are usually approached.

The wider research surface

Astrologer also publishes free public calculators covering individual techniques, a searchable glossary, a catalogue of chartable bodies including asteroids and fixed stars with their meanings, a 3D orrery for declination and out-of-bounds work, and a library of public-domain classical texts. These exist to be checked against, which is why they are public.
