Blood moon a sign of the end times?

Kerby Anderson has written,

Many prophecy teachers point to the fact that some verses of Scripture mention the moon turning to blood and believe this tetrad of blood moons might signal the end of the age. The first blood moon occurs today during Passover (April 15). The next takes place during the Feast of Tabernacles (October 8). Then a third occurs next Passover (April 4, 2015). And the last takes place during the following Feast of Tabernacles (September 29, 2015).

The question is, is this really a sign of the end times spoken of in Scripture? According to Mr. Anderson,

These are significant events in the heavens, but do they predict the return of Christ? Authors of books on the four blood moons usually point of a number of biblical passages, such as Joel 2, Matthew 24, and Revelation 6. I realize that Christians have different views of prophecy, but I think we might at least be able to agree on a basic interpretation of these passages.

Joel 2 was written to people who needed to repent. He prophesied about the "day of the Lord" and Revelation 14 seems to confirm that the prophet Joel was referring to Armageddon in his prophecy. Jesus in Matthew 24 talks about a great tribulation and predicts a time when the sun is darkened and the moon is not giving its light. A blood moon would only occur if the sun is giving its light. Likewise, you have in Revelation 6 the sun becoming black and the moon becoming like blood. Both of these verses seem to be talking about something supernatural not a lunar eclipse.

Admittedly, the coincidences are intriguing; however, we must point out that coincidences are not  necessarily mutually contingent and there may be other factors like for instance since the Jewish calendar is a lunar calender and the coincidence of the first blood moon falling on the Passover by necessity astronomically will place the other three blood moon on a Jewish holiday also. So, as with so much that goes with prophecy identifying the signs for and of fulfillment can sometimes get really wonky depending on the inclination or the predisposition of the interpreter. Therefore, I don't think I would hock the country store to wager a bet on this one. Besides, admittedly I am color blind, but it looks more orange than blood red to me. 

Furthermore, what these doomsday sayers neglect to tell you is that the coming four blood moons will be the eighth time this has happened since 1 AD. They mean nothing as far as the Bible is concerned, as far as I can see.

It has been my observation that prophecy is understood more thoroughly after the fact, consequently, it is best not to sell one's theology out to specifics which may or may not be there. As the song goes, "Que Sera, Sera (Whatever Will Be Will Be)" and I would just leave it there in the knowledge that we are safe and secure in His presence and forever safe there in HIs loving arms.
