Revelation 6:12 American King James version:
And I beheld when he had opened the sixth seal, and, see, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
Sounds like a solar eclipse to me. But I would think it would have to be visible from at least Israel to be considerable.

I think it more important to live a good life according to the Bible and hope when it comes you’re judged favorably.
So many people have believed it was the end when it wasn’t. There have been so many blood red moons and solar eclipses, (sun black as sackcloth). I think that is why Jesus said no one knows the day or the hour, he didn’t want us wasting time thinking too heavily on it, despairing, fearing. Best to live according to His Word and you will be on the ‘safe’ side of Armageddon.
However, speculation regarding both a lunar eclipse and a solar eclipse as being responsible for the particular prophecy in question is just not physically possible, not simultaneously it isn't. Refer to the respective mechanics of lunar or solar eclipse for insight if that doesn't make sense.
Therefore, another sort of event must provide the explanation for the descriptions contained in that prophecy. Darkened sun and reddened moon can have several different terrestrial explanations, all of which are due to a large amount of particulate matter obscuring the sun and causing a color shift in the visible spectra from the moon. A large volcanic eruption, nuclear war, asteroid strike (which appears to have been described in other prophecy so that's the explanation I favor), even a very large forest fire could do it.
We're commanded to keep watch and so it's good to do so, but in seeking explanations it's best to not veer into speculation that could invite ridicule. There's certainly enough of that already without encouraging more of it.
Regarding these “blood moons” occurring and recurring on significant dates in Jewish history, it's very tempting to attach great significance to such a thing. But, has this been independently confirmed? Well-meaning students of prophecy can and often do get carried away.
