This seems to be an astronomical question, not a Biblical one.
Have a look at this: http://www.timeanddate.com/eclipse/blood-moon.html
Here's an excerpt from the above site:
Another End-of-the-world Prophecy?
Some people believe that the tetrad has special significance because the eclipses coincide with important Jewish festivals. The two April lunar eclipses in 2014 and 2015 occurred at the same time as Passover, while the October and September eclipses occur during the Feast of Tabernacles. This, they suggest, is connected to a biblical prophecy of the end of times.
The fact is, eight of the tetrads since the first century have coincided with Jewish holidays without the world going under, so there is no reason to believe that the 2014-2015 tetrad will end the world this time either.
Attempts to link total lunar eclipses with Bible prophecy are superstitious nonsense.
