Blood Moon Tetrads and Triples

	In 2014, the first of 4 total lunar eclipses occurs on Passover (First Feast Day), April 15, 2014, followed by a solar eclipse on April 29, 2014, then the second total lunar eclipse occurs on the Feast of Succoth (Last Fall Feast Day), October 8, 2014, followed by another solar eclipse on October 23, 2014. In 2015, the Jewish religious year begins with the total solar eclipse March 20, 2015, then two weeks later the third total lunar eclipse occurs on Passover, April 14, 2015, and then the civil year beginning with the total solar eclipse on September 13, 2015 followed two weeks later by the fourth total blood red moon on the Feast of Succoth, September 28, 2015. Tetrads of four sequential lunar eclipses with no intervening partial lunar eclipses occurs 6 other times in this century, but this is the only time it occurs on the Jewish holy days of Passover and Feast of Tabernacles. The last time that four blood red moons occurred together was in 1967-1968, probably related to the recapture of Jerusalem by Israel. The time that the tetrad occurred before this was in 1949-1950, probably related to Israel becoming a nation. Before this time, the last occurrence was 1493-1494, probably related to the expulsion of the Jews from Spain. Since 1 AD, this tetrad has occurred on these holy days a total of 7 times. In 2014-2015, it will be the 8th time. It won't occur again for another 500 years.
