There are identifiable cycles of change in history. This online ephemeris demonstrates a clear relationship between the motions of slower-moving planets and historical events and trends.


Events and concrete changes in history often have their beginnings in the ideas, experiments and initiatives of people, occurring before the actual event. Astrology can identify the times when formative ideas and new trends take shape, and thus shape subsequent history.

Human free-will certainly does play an enormous role in historical events, yet it operates within the context of the nature of the times and the quirks or constraints of the 'energy-weather' at any time.

An astrological study of history isn't about 'fate' or determinism in history; instead it reveals an interaction between changing energy-conditions and our human responses to evolving situations. A study of astrological history shows the many ways that this process works. It describes the inner nature of the times, and the threads and tides underlying events.

The Historical Ephemeris could transform
your understanding of world history
and the deeper psychological processes lying behind it.



May this journey into the essence of historical time and change contribute to a wider and deeper understanding of world history. This is important, since we now live in a century of choice. Big choice.

This is the consequence not necessarily of astrological cycles or influences: it is a consequence of humanity's accumulated actions and choices to this day, within the context of those astrological influences. Over time we have made the choices we've made, and today the scope of our choice is accentuated enormously since the accumulated consequences are now with us more than ever before.


A note to astrologers without historical training: it is easy to cherry-pick and interpret events to fit one's astrological theories and predilections. A wider understanding of historical events is needed. The best way to do this is to study the history first, picking events considered to be significant, and only then to put it alongside the astrological data. Astrological motions don't always create the outcomes that astrological theory expects; on a Mars conjunct Pluto, it's just as likely that peace or war could break out - the 'god of war' has many tricks up his sleeves.

A note to historians with no astrological training: conventional history asserts that there is no inherent system or pattern to history. Therefore positing a 'theory of history' involving astrology can only be bunkum. This standpoint will one day change, and astrological theory will prove useful in informing a new understanding of world historical processes. This particularly concerns the largely unconscious psychological dynamics that hide behind historical events.

A note to astrologer-historians. You will enjoy this ephemeris. There's a lot here for you. Good luck!


About the making of the ephemeris

This research was done in 1988-93 (in UK, USA and New Zealand), with slight revisions in 1999 and 2012.

Heartfelt acknowledgements to the following people for their assistance and encouragement in the calculation and compiling of this work:

  • the late Neil Michelson, San Diego USA, for starting me off with valuable data in 1988;

  • Rob Hand of Astrolabe, Cape Cod USA, for providing computing facilities (using the AstroAnalyst program), and for his ideas and encouragement (1988-89);

  • Nancy Lavoie of Massachussetts, USA, for her help and encouragement;

  • the late Steve Hill in New Zealand for facilities and for understanding this work;

  • Sig Lonegren, once of Vermont USA, now in Glastonbury, England, a dowser and prehistorian who practically encouraged this astrologer in his work.

May the Historical Ephemeris give you endless hours of fascination!

Astro-historical tables for 2,500 years

The material contained in this ephemeris leads toward a new theory and understanding of history

Part One

Astrological groundrules
in historical timecycle research:

Part Two
Chronological timelines
with astrological data
600 BCE to CE 2000

Complete Timeline (7.4Mb): PDF

Each period covers one Neptune-Pluto cycle of 495ish years, covered in two tables each cycle. Each table is thus 250ish years long.

1. Ancient Period | 577–83 BCE
2. Empire Period | 83 BCE-CE 412
3. Light/Dark Ages | 412-905
4. Medieval Period | 905-1398
5. Early Modern Period | 1398-1892
6. Global Period | 1892 to 2000

Part Three

outer-planet configurations
600 BCE to CE 2200

Part Four

Tables of
outer planet movements

Part Five
A series of articles
on astro-historical timecycles

The Uranus-Neptune-Pluto conjunction of the 570s BCE

Uranus-Neptune-Pluto grand conjunction
578-575 BCE
In a sense the beginning of recorded history.
Before that, archaeology.
This is why this ephemeris starts at 600 BCE.
