... So, check this out ...
Today I had a 'hankering' to delve into the 1200 year Venus/Sun Grand Quintile [Pentagram] conjunction completion cycle. [Venus and Sun occupy another point on a Grand Quintile matrix [a Pentagram] every conj. and complete one every 5 times ...all 72 possibilities in apprx 1200 years. [as I do like to tinker with the algorithms in all the astro cycles that mesh with one another...] and I first ran across an article about a very special conj. Venus makes with the Sun about every 230 years...one happens to be due this June.
From Wiki [I believe we are not bound by the 100 word limit by quoting wiki as it is a public creation and in the public domain.]
"A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. The duration of such transits is usually measured in hours (the transit of 2004 lasted six hours). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is almost four times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth. Observations of transits of Venus helped scientists use the principle of parallax to calculate the distance between the Sun and the Earth.
Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities.
A transit of Venus took place on 8 June 2004 and the next will be on 6 June 2012. The previous pair of transits were in December 1874 and December 1882. After 2012, the next transits of Venus will be in December 2117 and December 2125."
...then here's the skinny on the lesser conj. that counts in this 'Grand Quintile' matrix 'dance'.
a ref. to a 1200 year cycle of pentagram matrices of Venus. This is from a page of a book I found online...you can read it at this link and then by scrolling to page 180 http://books.google.com/books?id=2X-fqV

1. June 9, 2008 @ 19* Gemini
2. Jan. 11, 2010 @ 22 Capricorn
3. Aug. 16, 2011 @ 23* Leo
4. March 28, 2013 @ 08* Aries
5. Oct. 25, 2014 @ 02* Libra
Here's the event chart for next March 28, 2013, you'll all notice that Uranus is @ 08* Aries 28' 11",an approaching conjunction to the USA natal Part of Transformation @ 09* Aries 29' 49" ...with the Sun/Venus conj. right behind it @ 08* Aries 10' 37" ... about to hit the USA Part of Transformation...One TWo THREE
[btw...from my proposed true birthchart of Jesus/Yeshua the natal Uranus of his was @ 08* Aries 12' 30" the Sun @ 11* Aries 52' 32']
Note; ...Pluto conj. the USA natal M.C. at the 12th of Capricorn
