While researching the relation between eclipses and the biblical calendar I found information about a crop circle from 2010 that points to May 20, 2012 as a significant date. There will be a celestial alignment that day between the Pleiades, the Sun, and the Earth as well as a partial solar eclipse.
On May 20th, 2012 an Partial Eclipse will cover the USA, Mexico, and half of the World. The "half circle" on the Crop Circle represents 0 (zero) on the Crop circle, which is "the day" the Pleiades, the Sun, and the Earth are "joined" together. This could be significant because we believe God's throne is in the North Heavens, possibly the Pleiades, and the Pleiades, the Sun, and the Earth are "JOINED" TOGETHER at this time.
