The Blood Moon Prophecy


Blood Moon is sometimes used to describe a Total Lunar Eclipse. When the Earth casts its shadow on a Full Moon and eclipses it, the Moon may get a red glow. Not every lunar eclipse is leading to a red moon, so the 2014-2015 tetrad is unique.

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned (in “syzygy“) exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon’s location relative to its orbital nodes.

A series of four total lunar eclipses is called a tetrad

The first Blood Moon eclipse in a series of four happened on the night of April 14-15, 2014. The second one took place on the night of October 7-8, 2014. The third one today  April 4, 2015 and visible to North American skywatchers. The fourth one will be on September 28, 2015.

The Blood Moon Prophecy

The term Blood Moon in Biblical prophecy appears to have been popularized by two Christian pastors, Mark Blitz and John Charles Hagee. They use the term Blood Moon to apply to the full moons of the ongoing 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) – beginning on the night of April 14-15, 2014  lunar eclipse as a sign of the end times as described in the Bible in Acts 2:20 and Revelation 6:12

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.

In 2014 – 2015 the rare sequence of Tetrad Red Blood Moon lunar eclipses are occurring on the Jewish Holidays of Passover and the Sukkot (Feast of Tabernacles). Two solar eclipses will also occur in 2015 on the Jewish New Years for KINGS and Feast of Trumpets Holidays.

revelation_bibleActs 2:20 The sun shall be turned into darkness, and the moon into blood, before the great and notable day of the Lord come
Joel 2:31 The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of the Lord come
Revelation 6:12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood

The description, 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.

Dates of Biblical prophecy Blood Moons in 2014 and 2015.

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

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

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

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, alunar 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.

Tetrads: Four Consecutive Total Lunar Eclipses 

April’s eclipse was the first to two total lunar eclipses in 2014. The second eclipse on October 08 and it too was visible from the USA. In this case, the western USA saw the entire eclipse while the eastern USA missed the end of the eclipse because the Moon sat while the eclipse was still in progress.

These two eclipses of were the first of four consecutive total lunar eclipses (each separated by six months) – a series known as a tetrad. The third and fourth eclipses of the tetrad occur on April 04, 2015 and Sept. 28, 2015 .

During the 5000-year period from 2000 BCE through 3000 CE, there are 3479 total lunar eclipses. Approximately 16.3% (568) of all total eclipses belong to one of the 142 tetrads occurring over this period. The mechanism causing tetrads involves the eccentricity of Earth’s orbit in conjunction with the timing of eclipse seasons. During the present millennium, the first eclipse of every tetrad occurs during the period February to July. In later millennia, the first eclipse date gradually falls later in the year because of precession.

Italian astronomer Giovanni Schiaparelli first pointed out that the frequency of tetrads is variable over time. He noticed that tetrads were relatively plentiful during one 300-year interval, while none occurred during the next 300 years. For example, there are no tetrads from 1582 to 1908, but 17 tetrads occur during the following 2 and 1/2 centuries from 1909 to 2156. The ~565-year period of the tetrad “seasons” is tied to the slowly decreasing eccentricity of Earth’s orbit. Consequently, the tetrad period is gradually decreasing (Meeus, 2004). In the distant future when Earth’s eccentricity is 0 (about 470,000 years from now), tetrads will no longer be possible.

The umbral magnitudes of the total eclipses making up a tetrad are all relatively small. For the 300-year period 1901 to 2200, the largest umbral magnitude of a tetrad eclipse is 1.4251 on 1949 Apr 13. For comparison, the magnitudes of some other total eclipses during this period are much larger. Two examples are the total eclipses of July 16, 2000 and June 26,2029 with umbral magnitudes of 1.7684 and 1.8436, respectively.

The table below gives the dates of each eclipse in the 8 tetrads occurring during the 21st century. The last tetrad prior to 2014 was in 2003-04 while the next group is in 2032-33.


In folklore, all the full moons have names. The names typically coincide with months of the year, or seasons. One of the most famous moon names is the 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.


Doomsday Theories 

doomsday theoryAs with many prophecy and folklore, doomsday theories and conspiracy theories are circulating  the internet and Youtube. This time predicting the world will end in September 2015 (varying from 23-28 Sept) by a huge asteroid being on a collision course with earth.

For those worried, there’s no known asteroid on a collision course with earth. Those are usually just fear mongering Doomsday Hoaxes.

  1. Usually I do not read article on blogs, but I wish to say that this
    write-up very forced me to try and do so! Your writing taste has been amazed me.
    Thanks, quite great post.


  2. You really make it seem so easy with your presentation but I find this topic to be actually something which I think I would never understand. It seems too complicated and extremely broad for me. I’m looking forward for your next post, I will try to get the hang of it!


  3. May I simply just say what a relief to find someone who genuinely knows what they’re discussing over the internet. You definitely understand how to bring an issue to light and make it important. More and more people ought to read this and understand this side of your story. I was surprised you’re not more popular since you most certainly possess the gift.
