My Sincere Apologies
While testing marriage dates extracted from the divorces list I realized there was a flaw in the way the random data is created. I set the lower and upper limits of the randomizing function to 1920 and 1982 (since the earliest marriage records were 2000, i.e. a minimum age of 18. I did not realize at the time that this would create, on average, a higher average age at the date of marriage, namely 52. The average age at the date of marriage for the actual data is 31. This creates a wider possible angle for the progressed Sun and Venus to fall in, and as a result, less chance of a correlation. I am posting this disclaimer right now, a couple of hours after realizing my mistake. As soon as possible I will adjust the randomizing function to generate birth dates that are, on average, the same as those of the live data, 31 years. This will no doubt reduce the percentage (which is currently about 70%). I'm hoping there will still be a significant percentage but will only know when it has been tested with these new lower and upper values. I am sorry if I've wasted your time, I've spent a month on this already and am feeling very bad about it right now as I really thought this was a true reflection of the bias. I think there will still be a bias but not so pronounced. I only found out weeks after developing this test page that 20 years ago an Australian named Paul Westran pretty much proved astrology to be valid using much the same approach, he calculates the date couples meet and shows that there is a higher prevalence of progressed Sun-Venus TRINES.
Progressed Planets Progressed planet influences work on a 'day for a year' basis from the day of your birth. A planet forming an aspect to your birth chart during the early days of your life influences you in the same manner when you are the same number of years old. For example, if the planet Venus forms a conjunction with your Sun when you are 30 days old, you can expect the same beneficial influence (a period of major love, marriage or birthing) when you are 30 years old. The closer the aspect is to 'exact' the stronger the influence, especially during the months or years when it is still approaching the exact aspect. This analysis currently uses a default orb of up to 5 degrees when calculating the progressed aspects. The default aspects analyzed are the conjunctions between the natal and progressed Sun and Venus positions. This bias is also prevalent with sextiles, and probably solar arcs (I will test those soon). Trines (120 degrees) are too wide to process. It works with a tighter orb too but it has been left fairly wide since it indicates a reasonable period around the marriage date when one can assume the person's love nature is enhanced, and often the exact marriage date does not correspond to the exact peak of the aspect. The 24732 marriage records analysed are from a Mexican marriage registry. 4373 additional marriage records are from the list of divorces.




You'll need a laptop to run the examples. They do run on a phone but take a long time due to the large output.
The data files contain both marriage partner birth dates (partner 1 and partner 2). More information about what is being demonstrated
