<P> The blood moon prophecy was a series of apocalyptic beliefs promoted by Christian ministers John Hagee and Mark Biltz, which state that a tetrad (a series of four consecutive lunar eclipses--coinciding on Jewish holidays--with six full moons in between, and no intervening partial lunar eclipses) which began with the April 2014 lunar eclipse is a sign of the beginning of the end times as described in the Bible in the Book of Joel, Acts 2: 20, and Revelation 6: 12 . The tetrad ended with the lunar eclipse on September 27--28, 2015 . </P> <P> On April 15, 2014, there was a total lunar eclipse which was the first of four consecutive total eclipses in a series, known as a tetrad; a second one took place on October 8, 2014, the third one on April 4, 2015, and the remaining one took place on September 27, 2015 . It is one of eight tetrads to take place during the 21st century AD . As with most lunar eclipses, the moon appeared red during the April 15, 2014, eclipse . The red color is caused by Rayleigh scattering of sunlight through the Earth's atmosphere, the same effect that causes sunsets to appear red . Hagee also connects the solar eclipse of March 20, 2015, in the middle of the sequence . </P>
