How We Map the
Sky to History

Celestial Data Sources

NASA JPL Ephemeris and Swiss Ephemeris provide all planetary positions, eclipse times, and aspect calculations. Data is verified to arc-minute precision. We use tropical zodiac positions standard in Western mundane astrology.

These are the same ephemeris tables used by academic astronomers, space agencies, and navigation systems worldwide. There is no ambiguity in the celestial data. A conjunction either occurred at a given degree on a given date, or it did not. The math is settled.

Historical Verification

Every world event is independently verified through primary historical sources, academic records, and established reference works. We cross-reference multiple sources. Dates are verified against the Julian/Gregorian calendar transition where applicable.

No event enters the archive based on a single source. Where historical dating is contested, we note the uncertainty. Where calendar systems differ, we convert to the standard Western calendar and document the conversion.

Correlation Standards

A celestial event must be active—within standard orb—at the time of the historical event. We do not backfit alignments to events. The temporal relationship must hold under scrutiny.

For eclipses: within the 6-month eclipse window. Eclipse influence is traditionally measured from the eclipse date forward, with the duration of effect proportional to the eclipse type and totality.

For conjunctions and oppositions: within 2° orb. The alignment must be applying or separating within this tight window at the time the historical event occurred.

For ingresses: the planet must be in the stated sign. When a planet stations retrograde near a sign boundary, we track the full ingress cycle including re-entries.

Significance Rating

Events are rated 1–5 based on four weighted factors:

Outer planet involvement. Pluto carries the highest weight, followed by Neptune, Uranus, Saturn, and Jupiter. The slower the planet, the rarer and more structurally significant the alignment.

Aspect type. Eclipse > conjunction > opposition > square > retrograde > ingress. Hard aspects between outer planets score highest.

Cardinal point activation. Alignments at 0° Aries, Cancer, Libra, or Capricorn carry additional weight. These are the structural hinges of the tropical zodiac.

Historical magnitude. The scale and lasting impact of the world event itself. A regional political shift scores lower than a world war or global pandemic.

What We Don't Claim

We do not claim causation. We present verified temporal correlations between celestial alignments and historical events. The data is real. The patterns are observable. The mechanism is unknown.

Whether these patterns are causal, symbolic, archetypal, or coincidental is left to the reader. We are not in the business of belief. We are in the business of documentation.

Intellectual honesty requires acknowledging the limits of the framework. Mundane astrology is not a predictive science in the modern sense. It is a pattern language—one that has been observed and refined over millennia, but one that resists the kind of controlled experimentation that modern science demands.

We find that honest acknowledgment of these limits makes the patterns that do emerge more compelling, not less. The data does not need exaggeration. It speaks clearly enough on its own.
