Here are the results and methodology I used to attempt rectification of the USA chart.  To try and make the results as objective as possible, I have used Jigsaw 2’s rectify feature and will report the numbers it gives using various techniques.

This remains a work in progress, but some of the results are interesting nonetheless. Click here to view the Jigsaw event file.

The first phase of this exercise was to gather historical data for the formation of the USA and its subsequent history. The events (dates only) I have used are as follows:

These are my own choices for events based on how well I feel these events are important in American, therefore they are somewhat subjective but I feel most Americans would agree that these were important events.  I have chosen not to use dates such as election days or inauguration of presidents (after Washington) due to the fact that these are set dates that could skew the results based on their regularity.  Some of the dates I’ve chosen are also too close together for Jigsaw to rectify to them accurately, so I will detail which events I’ve left out of the process.

The first date that I wanted to test in Jigsaw’s was July 4, 1776 in Philadelphia, PA.  I entered this date in Jigsaw with no time specified and used the auto rectify feature to allow the program to come to its own conclusions.  For this I had to throw out some events because there were events too close together in time for Jigsaw to deal with in this manner.  The events I disabled for this run were the Congress and Supreme Court dates which were too close to Washington’s inauguration, which I felt was the most significant event of the three.  I’ll return to these events in a different manner later.  I also exempted Lee’s surrender at Appomattox since it was only six days prior to Lincoln’s assassination.  The Bay of Pigs invasion also had to go due to its proximity to the first American in space.  Robert F. Kennedy’s assassination also had to be disabled due to the Martin Luther King Jr. assassination two months earlier.

After disabling these events, the July 4th Auto-rectification on 38 events gave these top four results with Jigsaw’s default settings:

(Points are in percentages)

Overall Hits:

Time Overall Percentage
9:33 a.m. 41
11:51 a.m. 35
7:29 p.m. 19
11:41 p.m. 27

At this point, I should explain that Jigsaw takes its defaults, calculates the aspects according to those defaults, and figures out by the orbs set whether an aspect was operative during the time of the event.  The Auto-rectify defaults for Jigsaw are: Transits from Uranus, Neptune and Pluto in the 2nd Harmonic (conjunction and opposition) to the Ascendant, Midheaven and Moon with an orb of 2 degrees; Secondary Progressions from the Ascendant and Midheaven to planets the Moon through Pluto and the Moon’s Mean Node also in the 2nd Harmonic with an orb of 1 degree; and Solar Arc Directions from the Ascendant and Midheaven to planets the Moon through Pluto and the Moon’s Mean Node also in the 2nd Harmonic with an orb of 1 degree.

After this, I wanted to change some of the defaults and see what it came up with.

First, I used 12th Harmonic transits (2 degree orb) of Uranus, Neptune and Pluto to the Ascendant, Midheaven and Moon only to the 4th of July date.  This came up with the same times as the above auto-rectification by using the defaults, but three times were tied at 13 percent hits and the 11:24 p.m. chart had a hit rate of 15 percent.

I then used the Secondary progressions from the progressed angles, Moon-Pluto and Node to the Ascendant, Midheaven and Moon in the 2nd Harmonic with a 1-degree orb.  The results of this test showed very low percentages, with the highest the 11:41 p.m. time with a 6 percent hit rate.

Next I tried Solar Arc Directions using the Angles, Moon-Pluto and Node to the Ascendant, Midheaven and Moon in the 2nd Harmonic with a 1degree orb.  9:33 a.m. gave 17 percent; 11:51 a.m. gave 26 percent; 7:29 p.m. gave 32 percent; and 11:41 p.m. gave 33 percent.

So each of the individual techniques gave the highest percentage to the 11:41 p.m. chart, which is highly improbable given the historical record.

I then moved on to configuring Jigsaw’s settings closest to the combination of methods I use most: Solar Arc Directions and Transits.  For the Solar Arcs I used the 4th Harmonic (since Jigsaw lacks the 8th Harmonic selection I prefer) to the Ascendant, Midheaven and Moon with a 1-degree orb; and for the transits also using the 4th Harmonic and using Mars through Pluto to the Ascendant and Moon with a 2-degree orb.  Using this combination, I got:

Time Overall Percentage
9:33 a.m. 17
11:51 a.m. 18
7:29 p.m. 19
11:41 p.m. 21

Realize, however, that this method has a total of 500 transit hits, so the results are negligible.

I then refined it to only the conjunction for transits to lessen the number of aspect hits to correlate to the charts. This gave slightly lower results of 15, 15, 16 and 18 percent for the respective time.

Using only Solar Arc Directions in the second harmonic to limit the number of available aspect hits gives a 17 percent result to the 9:33 chart, 26 Percent to the 11:51 a.m. chart, 32 percent to the 7:29 p.m. chart, and 33 percent to the 11:41 p.m. chart.

It seems that the rectification of the 4th of July chart through Jigsaw presents some problems.  It seems to prefer a time, 11:41 p.m. that is historically improbable.

The next phase is to test some of the other proposed charts for accuracy and see how they hold up.  For this, I’ll use my preferred transits from the Saturn to Pluto in the 4th Harmonic and Solar Arc Directions of Moon through Pluto to the Ascendant, MC and Moon of the proposed 4th of July charts.  Totals are merely adding the transit and Solar Arc totals and should not be considered a percentage, just a score.

Chart Transit Solar Arc Total
Sibley 5:10 p.m. 15 17 32
2:13 a.m. 13 22 35
Dobyns 9:36 21 17 38
Penfield 13 32 45
11:51 (Historical) 17 29 46

Of the July 4th charts`, the 11:51 a.m. and Penfield charts show the highest overall score, so I’ll include them in a future comparison.

Now let’s turn to some of the other possibilities.

Since we are not looking at just one day now, I’ve expanded the search to take the Sun into account as a radix point for transits and added in the Moon through Jupiter for the radix points to be searched for in the Solar Arc hits.  In addition, all charts were tested with only with events that occurred after the proposed chart with the latest date, the Supreme Court chart so that I was testing all charts with the same events.  As before, the total is merely the combined percentage numbers from Transits and Solar Arcs.  Unless noted, charts are set in Philadelphia, and all times are LMT.

Armistead July 2, 1776 15 33 48

Grimes (Articles of Confederation, 1 Mar 1781, 3:19 p.m. 14 34 48
Constitution Signing (Sep 17, 1787, 11:29 a.m.)  13 30 43
George Washington inauguration (30 Apr 1789, noon, New York, NY) 19 37 56

Supreme Court 26 Sep 1789, noon, in New York 20 32 52
July 4, 11:51 a.m. 21 31 52
Penfield July 4 16 33 49

Here are the score for the two most popular July 4th charts compared to those above:

July 4 2:13 a.m. 17 31 48
Sibley   5:10 p.m. 18 29 47

The highest combined scoring chart is that of Washington’s inauguration, which also scores highest by Solar Arc.  The highest scoring chart by transit is the July 4th,1776 11:51 a.m. chart.

The results are very close, actually.  The resonance to Washington’s inauguration may simply be due to the fact that many of the events in used in the test are presidential events.

The fact is, we have no concrete and “real” chart of the United States.  I agree with Nick Campion that each chart is valid as part of the evolution of the nation.  However, I did hope to test the efficacy of those charts people swear by and see if they held up to objective scrutiny.

The next phase of my examination will be gathering even more data of different types and testing the larger sample, along with splitting the events into different types to test different charts with.

I’d like to thank the following people for their data contributions and ideas:

Mark McDonough, Madalyn Hillis Dineen, Jayj Jacobs,, Lorenzo Smerillo, Susan Manuel and many others who I know I must have left out.
