Astrological watchers are looking forward to blood moon 2015, which will be happening on 27-28 of this month (date to defer based on location), but Christian preachers are spreading a false alarm among the public by claiming that something disastrous may happen on the day, the last blood moon of the tetrad.

A tetrad is a celestial event where four consecutive blood moons happen at approximately six-month interval. The current tetrad started with blood moon on 15 April, 2014, then on 8 October, 2014, 4 April, 2015, and will end with the 27-28 September event.

Some Christian preachers argued that the current tetrad is in sync with the Biblical prophecy of "End of the World" or prophecy of the apocalypse. They said that first blood moon of the tetrad coincided with the Jewish holy days Passover, the second fell on the Feast of the Tabernacle, third fell on the Passover, and the final blood moon of the tetrad on 28 September will mark the Feast of the Tabernacle.

"The last time there was a tetrad was back in the 1900s, and to my amazement, they also fell on the feasts of Passover and Tabernacles," pastor Mark Blitz of El Shaddai Ministries, who wrote the book "Blood Moons: Decoding the Imminent Heavenly Signs," told Express. "When I noticed the years these phenomena occurred, my mind began reeling. The last two times there were four blood moons in a row, they happened, first, right after Israel became a nation in 1948, and then again when Israel retook Jerusalem in 1967." He claimed that earthquakes will hit the world more often, which is a sign of second coming of Jesus Christ.

Pastor John Hagee, whose book "Four Blood Moons" has been made into a movie with the same title, told CNN that "The coming four blood moons points to a world-shaking event that will happen between April 2014 and October 2015." 

Mormon author Julie Rowe, who wrote two books that urge the people to prepare for the end of the world, too is said to have endorsed blood moon prophecy. In fact, News website reported that members of the Church of Jesus Christ of Latter Day Saints in Utah have started stocking up food items and other essential goods fearing earthquake and other natural calamities during the blood moon. 

However, "End of the World" prophecy has no scientific basis. Blood moon is just another astronomical phenomenon where supermoon and total lunar eclipse occur at the same time. Tetrad is a rare event but it has happened in the past and will happen again.

NASA said in a statement that it is a rare celestial event -- convergence of total lunar eclipse, full moon nearest the fall equinox, closest approach to Earth for the year -- that has happened only five times since 1900, the last being in 1982, and the next, after this month, supposed to occur in 2033.
