Signs in the Heavens of a Four Blood Moon in 2014 and 2015

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):

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 eclipse?

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.

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.
