What is a Blood Moon?

Want to know the dates for the Blood Moons and total lunar eclipses in 2014 and 2015? You’ve come to the right place …

We have been receiving a number of inquiries about some upcoming Blood Moons in the years 2014 and 2015. And we want to say, first of all, that the Blood Moons most people are asking about are not part of astronomy. Instead, their origin is religious, at least according to Christian pastor John Hagee, who wrote a 2013 book about Blood Moons. More about that below. Still, since they’re moons, and since people are asking us, we wanted to reply.

Hunter’s Moon collage from EarthSky Facebook friend Kausor Khan in Hyberabad, India. Notice that she choose reddish moons to depict the Hunter’s Moon. That’s because many people see the Hunter’s Moon low in the sky, and moons seen low in the sky appear reddish. In 2013, the Hunter’s Moon – sometimes called the Blood Moon – came in mid-October.

Blood Moons in astronomy. In astronomical lore, all the full moons have names. The names typically coincide with months of the year, or seasons.

One of the most famous moon names isthe Hunter’s Moon. It is the the full moon immediately following the Harvest Moon, which is the full moon occurring most closely to the autumnal equinox.

The Hunter’s Moon, in skylore, is also sometimes called the Blood Moon. Why? Probably because it’s a characteristic of these autumn full moons that they appear nearly full – and rise soon after sunset – for several evenings in a row. Many people see them when they are low in the sky, shortly after they’ve risen, at which time there’s more atmosphere between you and the moon than when the moon is overhead. When you see the moon low in the sky, the extra air between you and the moon makes the moon look reddish. Voila. Blood moon.

Why is a Hunter’s Moon linked in people’s minds with a red moon? First of all, in autumn, the angle of the ecliptic – or sun and moon’s path – makes a narrow angle with the horizon. Image via classicalastronomy.com.

Secondly, the narrow angle of the ecliptic means the moon rises noticeably farther north on the horizon, from one night to the next. So, every autumn, there is no long period of darkness between sunset and moonrise. Around the time of full moon, many people see the moon low in the sky, around the time of twilight. At that time, the moon often looks reddish. Image via classicalastronomy.com.

Blood Moons in Biblical prophecy. We’re not experts on prophecy of any kind. But we’ll tell you what we know about the new definition for Blood Moon that has caused so many questions recently.

From what we’ve been able to gather, two Christian pastors, Mark Blitz and John Hagee, use the term Blood Moon to apply to the full moons of the upcoming tetrad – four successive total lunar eclipses, with no partial lunar eclipses in between, each of which is separated from the other by six lunar months (six full moons) – in 2014 and 2015. John Hagee appears to have popularized the term in his 2013 book Four Blood Moons: Something is About to Change.

Mark Blitz and John Hagee speak of a lunar tetrad as representing a fulfillment of Biblical prophecy. After all, the moon is supposed to turn blood red before the end times, isn’t it? As described in Joel 2:31 (Common English Bible):

The sun will be turned to darkness, and the moon to blood before the great and dreadful day of the LORD comes.

That description, by the way, describes both a total solar eclipse and total lunar eclipse. Sun turned to darkness = moon directly between the Earth and sun in a total solar eclipse. Moon turned to blood = Earth directly between the sun and moon, Earth’s shadow falling on the moon in a total lunar eclipse.

We astronomy writers often describe total lunar eclipses as appearing blood red. Why red? They appear reddish because sunlight from all of Earth’s sunrises and sunsets is scattered by the Earth’s atmosphere and falls on the surface of the eclipsed moon. In years where volcanic activity is pronounced, however, a total lunar eclipse may appear more brownish or gray in color.Read more here: Why does the moon look red during a total lunar ecl...

Dates of Biblical prophecy Blood Moons in 2014 and 2015. These are the dates for the upcoming tetrad – four successive total lunar eclipses – in these years.

2014:
Total lunar eclipse: April 15
Total lunar eclipse: October 8

2015:
Total lunar eclipse: April 4
Total lunar eclipse: September 28

There are a total of 8 tetrads in the 21st century (2001 to 2100). But proponents of this Biblical prophecy regard the upcoming tetrad as especially significant because it coincides with two important Jewish holidays: Passover and Tabernacles.

The April 2014 and April 2015 total lunar eclipses align with the feast of Passover. The October 2014 and September 2015 total lunar eclipses align with the feast of Tabernacles.

The Jewish calendar is a lunar calendar. In any year, it’s inevitable that a full moon should fall on or near the feasts of Passover (15 Nissan) and Tabernacles (15 Tishri). Nissan and Tishri are the first and seventh months of the Jewish calendar, respectively.

It is somewhat ironic that three of these four lunar eclipses are not visible – even in part – from Israel. The only eclipse that can be seen at all from Israel is the tail end of the September 28, 2015 eclipse, which may be observable for a short while before sunrise.

How common is a tetrad of total lunar eclipses? Depending upon the century in which you live, a lunar tetrad (four consecutive total lunar eclipses, spaced at six lunar months apart from one another) may happen fairly frequently – or not at all.

For instance, in our 21st century (2001-2100), there are a total 8 tetrads, but in the 17th, 18th and 19th centuries, there were none at all. If we include all the centuries from the 1st century (AD 1-100) through the 21st century (2001-2100), inclusive, there are a total of 62 tetrads. The last one occurred in 2003-2004, and the next one after the 2014-2015 tetrad will happen in 2032-2033.

However, if we want to know which tetrads specifically fell on the Jewish feasts of Passover and Tabernacles, there appear to be a total of 8 in these 21 centuries:

1. 162-163 C.E. (Common Era)
2. 795-796 C.E.
3. 842-843 C.E.
4. 860-861 C.E.
5. 1493-1494 C.E.
6. 1949-1950 C.E.
7. 1967-1968 C.E.
8. 2014-2015 C.E.

Why is the term Blood Moon being used to mean a full moon of a lunar tetrad? We can’t really tell you why more and more people are using the term Blood Moon to describe the four full moons of a lunar tetrad. We don’t know why, exactly.

Here’s the definition of a lunar tetrad, again: four successive total lunar eclipses, with no partial eclipses in between, each of which is separated from the other by six lunar months (six full moons). There’s no obvious reason why Blood Moon should be associated with this term.

To the best of our knowledge, however, the use of the term Blood Moon to describe a lunar tetrad is of recent origin. It might have originated with John Hagee’s 2013 book.

We’re still not sure whether Blood Moon pertains to the full moon of any tetrad, or specifically to a tetrad that coincides with the feasts of Passover and Tabernacles.

Either way, I suspect the nouveau definition of Blood Moon will gain traction as we approach the tetrad, the four total lunar eclipses of 2014 and 2015.

Bottom line: The term Blood Moon in astronomy in sometimes used as another name for the Hunter’s Moon. The term Blood Moon in Biblical prophecy appears to have been popularized by two Christian pastors, Mark Blitz and John Hagee. They use the term Blood Moon to apply to the full moons of the upcoming tetrad – four successive total lunar eclipses, with no partial lunar eclipses in between, each of which is separated from the other by six lunar months (six full moons) – in 2014 and 2015. Astronomers will not be using the term Blood Moon to describe these four upcoming lunar eclipses.

Why does the moon look red during a total lunar eclipse?

During a total lunar eclipse, Earth’s shadow on the moon often looks red. Why?

During a lunar eclipse, you’ll see the Earth’s shadow creeping across the moon’s face. The shadow will appear dark, like a bite taken out of a cookie, until the shadow completely covers the moon. Then, during the breathtaking time of totality, the shadow on the moon’s face often suddenly changes. Instead of dark, it appears red. Why?

The reason stems from the air we breathe. During a total lunar eclipse, the Earth lies directly between the sun and the moon, causing the Earth to cast its shadow on the moon. If Earth didn’t have an atmosphere, then, when the moon was entirely within Earth’s shadow, the moon would would appear black and invisible.

Thanks to Earth’s atmosphere, what actually happens is much more subtle and beautiful.

Earth’s atmosphere extends about 50 miles (80 kilometers) above Earth’s surface. During a total lunar eclipse, when the moon is submerged in Earth’s shadow, there is circular ring around Earth – the ring of our atmosphere – through which the sun’s rays pass.

Sunlight is composed of a range of frequencies. As sunlight passes through our atmosphere, the green to violet portion of the light spectrum is, essentially, filtered out. This same effect, by the way, is what makes our sky blue during the day. Meanwhile, the reddish portion of the spectrum is least affected.

What’s more, when this reddish light first entered the atmosphere, it was bent (refracted) toward the Earth’s surface. It’s bent again when it exits on the other side of Earth. This double bending sends the reddish light onto the moon during a total lunar eclipse.

At right, the fully eclipsed moon takes on the reddish color of sunlight filtered and refracted through Earth’s atmosphere. Photo Credits: JAXA (left), Jim Fakatselis (right). Images via AstroBob

Depending on the conditions of our atmosphere at the time of the eclipse (dust, humidity, temperature and so on can all make a difference), the surviving light will illuminate the moon with a color that ranges from copper-colored to deep red.

In December 1992, not long after the eruption of Mount Pinatubo in the Philippines, there was so much dust in Earth’s atmosphere that the totally eclipsed moon could barely be seen.

Can anyone know in advance how red the moon will appear during a total lunar eclipse? Not precisely. Before an eclipse takes place, you’ll often hear people speculating about it. That uncertainty is part of the fun of eclipses, so enjoy! And watch for the red moon during a lunar eclipse.

Bottom line: A moon may look red during a total lunar eclipse because of sunlight that is filtered and refracted by Earth’s atmosphere.

thanks , I was just reading about these that are suppose to happen in 2014 and 2015 , for the Jews they are suppose to  mean, some kind of event that is suppose to happen ? to bad they cant tell us what that suppose is ? its always a after occurrence , that we hear about , not much foresight if you ask me . they wont be visible to the Holy Land , but never the less, they will happen just the same , I have often wondered why these people have felt themselves so tormented by a God that was suppose to love them ? and choose them ? BB

Quite an interesting post. Yes, they have coined that name for all the reasons here described.

Fanthumofthewinds, prophecies can not work because we all have not only will power and a choice, but because the World is our own to create. How can anyone else but me, know what I am about to create in my World?

 are not prophecies that which is to come .. foresight , Edward Casey, Nostradamus , ect ? and Of course we create , that which is in our own ' individual world ', I'm speaking as a whole ? I can change my curtains , I can change my car , I can change my address, I can change jobs , professions , ect these are personal world. So if this is the case then I must ask what is it that they as a whole are creating in theirs ? BB     

What an astoundingly profound statement Carmen! 

May I ask you, Fantumofthewinds, who is they?

Is there anyone else more porwerful than you?

Is there a big guy in the sky that moves anything, other than we do?

Do we not create the entire World?

Is not the World an accumulation of all of us?

Therefore if each individual is individually creating, it is us that are changing the World, and since I can only change my little part, how can I predict what others are going to do?

 

 I think this conversation was on the Jewish nation , so I would guess" they" are the They,, As I think this is who I was speaking of, when I answered this . after all it's supposed to be connected to them .  

Romans 2:29

"But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God."
