The words “blood moons” and “lunar tetrad” are being used in media and religious circles. But what do they mean? It is suggested author John Hagee, popularized the term “blood moon” in his 2013 book: Four Blood Moons, Something is About to Change. However I found that the October moon was called the blood moon in Medieval times.
The moon undergoes a lunar eclipse when the earth gets between the sun and the moon, and blocks direct sun on the moon, causing only the glow to hit the moon. Since the sun’s rays are passing through earth’s atmosphere, which filters out green to violet, the major light waves that reach the moon are red. The moon may appear pinkish or reddish. Because of the reddish color, it is called a blood moon.
On the left of the above picture is the earth seen by an astronaut standing on the moon during a lunar eclipse, and a blood moon as seen from the earth.
A lunar tetrad, which already started with the lunar eclipse (blood moon) on April 14th and 15th, is “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.” (http://earthsky.org/space/what-is-a-blood-moon-lunar-eclipses-2014-2015#tetrad).
There are eight tetrads from 2001 to 2100. But the current tetrad is thought to be significant by many because each lunar eclipse falls on a Jewish holiday—either the feast of Tabernacles or the Passover feast.
The dates of the blood moons and a solar eclipse are:
10/08/2014….Feast of Tabernacles
03/20/2015….Total Solar Eclipse
09/28/2015….Feast of Tabernacles
Using Biblical prophecy, three authors, Mark Hitchcock, John Hagee and Mark Blitz write of what they feel the significance of these astrological events are. The reference verse is Joel 2:31: “The sun will be turned into darkness and the moon into blood before the great and awesome day of the Lord comes.” While not predicting a date, they see events transpiring which they feel are predicted.
There are other names for the moons. I have seen the Harvest Moon rise behind the combine over a wheat field. It is the moon closest to the autumnal equinox. It is huge and reddish and beautiful, and casts a coppery orange glow on the windrows of grain. Some sources say the Hunter’s Moon, which is the full moon after the Harvest Moon, is also called a blood moon because of that reddish appearance as it rises.
Dating back to eastern Native American labeling, there is the Full Wolf Moon, Full Snow, Full Worm, Full Pink, Full Flower, Full Strawberry, Full Buck, Full Sturgeon, Full Corn or Harvest, Full Hunter, Full Beaver and the Full Cold or Full Long Nights Moon. At http://home.hiwaay.net/~krcool/Astro/moon/moonnames.htm you will find many more moon names depending on what culture or nationality you examine. The June moon for Celtics is the Moon of Horses!
Songs have been written about the moon, poems and fairy tales tell of its power, or the man in the moon. Moonlight is romantic. And a boy might “moon” over a girl if he likes her. You can listen to and read lyrics of multiple moon songs at http://www.moonlightsys.com/themoon/lyrics.html.
Obviously the moon has been an important player in lives since the beginning. Might it be an important player at the end?
