Is there biblical basis for the "blood moons"? Most of the members of Christianity.SE have probably heard about the latest craze on the subject of End Times prophecy - the Blood Moons.

We are currently in the midst of what is referred to as a lunar tetrad, a period of time in which we experience a series of four consecutive total lunar eclipses, with six full moons in between, and no intervening partial lunar eclipses over a course of two years (two one year, two another), and fuelling this further is the fact that these moons usually occur on Jewish feast days. Those who teach that this sign is miraculous will note that these lunar tetrads have occurred in the past either on other Jewish feast days, or other major events in Jewish history.

While that certainly makes for a good story, research will show that these events occur on feast days because the Hebrew calendar (and thus, Jewish holidays/feast days) are based on a lunar cycle, so they aren't necessarily uncommon. And while positing that these are rare, we see they have occurred some 60+ times in the past.

Now, I know that Revelation and other Old Testament prophecy tells us the moon becomes red and the sun black, but being a prophecy intended (because of it's OT roots) for Israel, which to me would indicate both the sun and the moon taking on these colors in the sky at once, hardly an eclipse of this kind.

Are there any other biblical sources for the blood moons? Or is this more or less a cry for attention?
Joel 2:31 is an end time prophecy that features a blood moon and a solar eclipse.

Douay-Rheims Joel 2:31


  The sun shall be turned into darkness, and the moon into blood: before
  the great and dreadful day of the Lord doth come.


John Hagee and many protestants think that end times prophecy is all about the nation of Israel and the Third Temple of Jerusalem, but I would remind them that God did not allow Julian the Apostate to rebuild the temple and invalidate Christ's words in Matthew 24:1-2, so I don't see why he's going to allow it this time. 


  And Jesus being come out of the temple, went away. And his disciples
  came to shew him the buildings of the temple. [2] And he answering,
  said to them: Do you see all these things? Amen I say to you there
  shall not be left here a stone upon a stone that shall not be
  destroyed.


The Historian Ammianus Marcellinus (A.D. c.330 - 395) 
"Res Gestae," Book XXIII


  He [Julian the Apostate] planned at vast cost to restore the once
  splendid Temple at Jerusalem, which after many mortal combats during
  the siege by Vespasian and later by Titus had barely been stormed. He
  had entrusted the speedy performance of this work to Alypius of
  Antioch... But though this Alypius pushed the work on with vigor,
  aided by the governor of the province, terrible balls of fire kept
  bursting forth near the foundations of the Temple and made the place
  inaccessible to the workmen, some of whom were burned to death; and
  since in this way the element persistently repelled them, the
  enterprise halted. ("cum itaque rei idem fortiter instaret Alypius
  iuvaretque provinciae rector, metuendi globi flammarum prope
  fundamenta crebris adsultibus erumpentes fecere locum exustis
  aliquotiens operantibus inaccessum, hocque modo elemento destinatius
  repellente cessavit inceptum.")
