Moon Phases Pic
Full Moon names date back to Native American Indians of the northern and eastern United States. Tribes kept track of the seasons by giving distinctive names to each recurring Full Moon. Their names pertained to the entire month in which each occurred. There was some variation in the names, but generally the same ones were current throughout the Algonquin tribes from New England to Lake Superior. European settlers followed the custom and even created some of their own. A few names are duplicated in subsequent months because of different regional locations of the tribes. A lunar month averages about 29.5 days and the Full Moon dates change from year to year. Click on a month or name listed in the index below to see full names and descriptions.

WORM MOON
As the temperature becomes warmer and the ground begins to thaw, earthworm casts reappear along with the return of robins. The northern tribes called this the Crow Moon, with the cawing of crows signaling the end of winter. Also known as the Crust Moon because the snow becomes crusted from thawing by day and freezing at night. The Sap Moon marked the time of tapping maple trees. Settlers also knew this as the Lenten Moon. A biblical name referring to the last full Moon of winter.

This name is from the pink grass/moss or wild ground phlox, one of the earliest widespread of flowers in spring. Other names include Sprouting Grass Moon and Egg Moon. The name Fish Moon came from the coastal tribes because the shad swam upstream to spawn. This is the first Full Moon of spring and it's also known as the Paschal Moon. The feast of Passover begins at sundown on this night and the first Sunday following the first Full Moon of spring is designated as Easter Sunday.

Traditionally, this name is for the Full Moon that occurs closest to the Autumn (Fall) Equinox. In two out of three years the Harvest Moon comes in September, but every third year it occurs in October. At the peak of the harvest, farmers can work into the night by the light of this Moon. A definite plus for the farmer. Fruit Moon or Barley Moon are names reserved for those years when the Harvest Moon appears very late in September or in early October.

COLD MOON
Also known as the Long Nights Moon among some tribes. During this month the winter cold is gripping and nights are at their longest and darkest. It is sometimes called the Moon before Yule. (the full moon before Christmas) The name Long Night Moon is doubly appropriate because the midwinter nights are indeed long and the Moon is above the horizon for a long time. The midwinter Full Moon has a high trajectory across the sky because it's directly opposite to the low Sun.

BLACK MOON

A Black Moon is also known as a New Moon or a Dark Moon.
Being the opposite of a Blue Moon, a Black Moon is the
3rd New Moon in a season having 4 New Moons.
The next seasonal Black Moon occurs 5/20/2012 @ 6:47pm CDT.

Any month containing 2 New Moons, the 2nd is labeled a Calendar New Moon.
It is believed that the second New Moon has great spiritual powers.
The next calendar Black Moon occurs on 7/30/2011 @ 1:40pm CDT.

(Due to different time zones, dates and times will vary.)
Moon Cycle Pic




























BLUE MOON

Each season contains at least 3 Full Moons. These Moons are known as the 1st, 2nd and Last Full Moon and each bear a distinctive name. The Equinox and Solstice dates are used for dividing the seasons and some seasons will contain 4 Full Moons. This additional Moon is a true "Blue Moon" and it's the 3rd Full Moon of a season, between the 2nd and Last Moon. This is the older meaning of Blue Moon.
The next seasonal Blue Moon occurs 8/20/2013 @ 8:45pm CDT.

In recent times, the Blue Moon has been based on the Gregorian Calendar and has come to be known as a Calendar Blue Moon. Since a Lunar Month averages about 29.5 days, there will occasionally be seasons with 4 Full Moons, creating a calendar month with 2 Full Moons. The 2nd Moon in a month is called a Calendar Blue Moon. These Moons are not as frequent and on average occur every 2.72 years.
The next calendar Blue Moon occurs 8/31/2012 @ 8:57am CDT.

(Due to different time zones, dates and times will vary.)

HARVEST MOON

The Harvest Moon is always the Full Moon closest to the Autumnal Equinox. If the Harvest Moon occurs in October, the September Full Moon is usually called the Corn Moon. The names Barley Moon and Fruit Moon are reserved only for those years when the Harvest Moon appears very late in September or in early October. About every 4 years the Harvest Moon occurs in October, depending on the cycles of the moon. The Autumnal Equinox for 2009 is September 22nd.

The Harvest Moon for 2011 is September 12th @ 4:27am CDT.
(the night of 9/11 thru the early morning of 9/12)

WET MOON and DRY MOON (aka CHESHIRE MOON)

A Wet Moon is when the horns of the Crescent Moon point up at an angle, away from
the horizon. It appears this way during the Summertime in the Northern Hemisphere.

A Dry Moon is when the horns of the Crescent Moon point to the side.
It appears this way during the Wintertime in the Northern Hemisphere.

Absent New Moon and Full Moon

Occasionally, the month of February will not have a New Moon . This is the only month effected
by this strange occurrence. When this happens, January and March will each have 2 New Moons.
The next February without a New Moon will be in 2014.

This same phenomenon happens with the Full Moon. When February does
not have a Full Moon, January and March will each have 2 Full Moons.
The next February without a Full Moon will be in 2018.

PERIGEE and APOGEE MOONS

Some full Moons are genuinely larger than others. It's no illusion. The Moon's orbit is an ellipse with one side 50,000 km closer to Earth than the other. The Moon's orbit periodically grows rounder and then more oval; it is never a perfect circle. The two extremes are called "perigee" (nearby) and "apogee" (far away).

Perigee - The point at which the Moon is nearest Earth each month is called a "perigee" and it varies throughout the year. A perigee Moon brings with it higher tides called "perigean tides". In most places, lunar gravity at perigee pulls tide waters only a few centimeters higher than usual. This gravitational pull can also cause weather to become more unstable. It's moonlight shining through icy winter air can produce beautiful halos, coronas, moondogs and other atmospheric optics phenomena. The Full Moon will be closest to the earth in 2011 on March 19th 2:10pm CDT.

Apogee - The point at which the Moon is farthest from Earth each month is called an "apogee". This also varies throughout the year. At apogee, the lunar gravity pulls tide waters fewer centimeters lower than usual. The gravitational pull on the earth is the opposite of Perigee. The Full Moon farthest from the earth in 2011 will be on October 12th 6:44am CDT.

VERNAL EQUINOX or SPRING EQUINOX
March 20, 2011 @ 6:21pm CDT


Most of us recognize this date as the beginning of Spring. As well as signifying changing seasons, March 20 (March 21 in some years), the Sun crosses directly over the Earth's equator, from south to north. This moment is known as the Vernal Equinox in the Northern Hemisphere. People south of the Equator get ready for the cooler temperatures of Autumnal Equinox.

The Vernal Equinox has been recognized for thousands of years. Along with the coming of Spring, the date is also significant in Christianity. Easter falls on the first Sunday after the first full moon that occurs after the Vernal Equinox.

(Due to different time zones, dates and times will vary.)
Moon Cycle Pic




























SUMMER SOLSTICE
June 21, 2011 @ 12:16pm CDT


This is when we experience the longest day of the year. People in the Northern or Southern Hemispheres experience the same phenomenon. For several days before and after each solstice, the sun appears to stand still in the sky. More specifically the noontime elevation does not seem to change. Solstice comes from the Latin meaning sun stands still. It signifies the beginning of Summer north of the Equator. Those south of the Equator will begin their Winter season. The Sun's position reaches its greatest distance above the equator, about 23 1/2 of arc. During the Summer Solstice, the sun is directly overhead at noon and over the Tropic of Cancer.

(Due to different time zones, dates and times will vary.)
Moon Cycle Pic




























AUTUMNAL EQUINOX or FALL EQUINOX
September 23, 2011 @ 4:04am CDT


A second equinox occurs each year on September 22 or 23 as the Sun crosses directly over the Earth's equator, from north to south. It marks the beginning of Fall. It's known as the Autumnal Equinox in the Northern Hemisphere. At the same moment the Southern Hemisphere is entering into Spring, or the Vernal Equinox.

(Due to different time zones, dates and times will vary.)
Moon Cycle Pic




























WINTER SOLSTICE
December 21, 2011 @ 11:30pm CST


A second Solstice occurs each year at noon on December 21 or 22. The Winter Solstice marks the shortest day and the longest night of the year. The the sun is directly overhead at noon and shines over the Tropic of Capricorn, below the Equator. This Solstice marks the beginning of Winter in the Northern Hemisphere and Summer in the Southern Hemisphere. For several days before and after each solstice, the sun appears to stand still in the sky in both the Northern and Southern Hemispheres. More specifically the noontime elevation does not seem to change. The Sun's position reaches its greatest distance below the equator, about 23 1/2 of arc. Solstice comes from the Latin meaning sun stands still.

(Due to different time zones, dates and times will vary.)
Moon Cycle Pic




























WHAT IS AN EQUINOX?

The word Equinox means "Equal Night". Because the sun is positioned above the Equator, day and night are about equal in length all over the world during both Equinoxes. These brief but monumental moments are due to the 23.4 degree tilt of the Earth's axis. We receive the Sun's rays more directly in the summer because of the tilt. In the winter, we are tilted away from the Sun causing lower temperatures.

Without the tilt of the Earth's axis, there would be no variation in the length of day and night. The temperatures would remain the same throughout the year and we would not have seasons.
Moon Cycle Pic




























WHAT IS A SOLSTICE?

In the Northern Hemisphere the longest day and shortest night of the year occur, marking the beginning of Summer. It's the reverse for the Southern Hemisphere. In March, the the Sun shines over the Tropic of Cancer at noon, above the Equator. In December, the the Sun shines over the Tropic of Capricorn at noon, below the Equator. During the two Solstices, the Sun is at its greatest distance from the Equator. For several days before and after each solstice, the sun appears to stand still in the sky. More specifically the noontime elevation does not seem to change. The Sun's position has reached its greatest distance above the equator, about 23 1/2 of arc.

Moon Line Pic



New Moon PicNew Moon: The lighted side of the Moon faces away from the Earth. This means that the Sun, Earth, and Moon are almost in a straight line, with the Moon in between the Sun and the Earth. The Moon is not visible or looks very dark (except during a solar eclipse).
Waxing Crescent Moon Pic Waxing Crescent Moon: This Moon can be seen after the New Moon, but before the First Quarter Moon. This crescent will grow larger and larger every day, until the Moon becomes a First Quarter Moon.
First Quarter Moon PicFirst Quarter Moon: The right half of the Moon appears lighted and the left side of the Moon appears dark. During the time between the New Moon and the First Quarter Moon, the part of the Moon that appears lighted gets larger and larger every day, and will continue to grow into a Full Moon.
Waxing Gibbous Moon PicWaxing Gibbous Moon: This Moon can be seen after the First Quarter Moon, but before the Full Moon. The amount of the Moon that we can see will grow larger and larger every day. Waxing means increasing, or growing larger.
Full Moon PicFull Moon: The lighted side of the Moon faces the Earth. This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle. The Moon that we see is very bright from the sunlight reflecting off it.
Waning Gibbous Moon PicWaning Gibbous Moon: This Moon can be seen after the Full Moon, but before the Last Quarter Moon. The amount of the Moon that we can see will grow smaller and smaller every day. Waning means decreasing, or growing smaller.
Last Quarter Moon PicLast Quarter Moon: Sometimes called Third Quarter. The left half of the Moon appears lighted, and the right side of the Moon appears dark. During the time between the Full Moon and the Last Quarter Moon, the part of the Moon that appears lighted gets smaller and smaller every day. It will continue to shrink into a New Moon, then the cycle starts all over again.
Waning Crescent Moon PicWaning Crescent Moon: This Moon can be seen after the Last Quarter Moon and before the New Moon. This crescent will grow smaller and smaller every day, until the Moon becomes a New Moon.

Moon Revolving Pic   More on the Moon  Moon Revolving Pic


Phases of the Moon ~ The revolution of the Moon around the Earth makes the Moon appear as if it's changing shape in the sky. This is caused by the different angles from which we see the bright part of the Moon's surface. The Moon passes through eight distinct, recognized stages during a cycle that repeats itself every 29.5 days (a lunar month). Four of those stages are considered major shapes. These are called "Phases" of the Moon.


A lunation is a lunar month, during which time the Moon completely circles the Earth in its orbit. Two other effects can be easily seen. First, due to the elliptical shape of the Moon's orbit, the apparent size of the Moon's disk changes as its distance from Earth varies. Second, although the Moon's near side directly faces the Earth on average, we get to view the Moon from slightly different angles as it orbits us. This effect is called libration and is caused partly by the tilt of the Moon's rotation axis with respect to its orbital plane. Also partly because the Moon's speed in its orbit varies but its rotation rate does not.


New Moon, First Quarter, Full Moon, and Last Quarter phases are considered to be primary phases and their dates and times are published in almanacs and on calendars. The two crescent and two gibbous phases are intermediate phases, each of which lasts for about a week between the primary phases.


The phases designate both the degree to which the Moon is illuminated and the geometric appearance of the illuminated part and always follow one another in the same order. During each lunar month, we see the Moon's appearance change from not visibly illuminated through partially illuminated to fully illuminated, then back through partially illuminated to not illuminated again.


The first time that the thin waxing crescent Moon is visible after New Moon (low in the evening sky just after sunset) marks the beginning of a month in the Islamic Calendar. A New Moon occurs when the Sun and Moon are quite close together in the sky. Full Moons occur when the Sun and Moon are at nearly opposite positions in the sky. This is why a Full Moon rises about the time of sunset and sets about the time of sunrise, for most places on Earth. The First and Last Quarters occur when the Sun and Moon are about 90 degrees apart in the sky. In fact, the two "half Moon" phases are called First Quarter and Last Quarter because they occur when the Moon is one- and three-quarters of the way around the sky (along its orbit) from New Moon.


When counting the number of days from a New Moon to one of the Moon Phases is called the Moon's "Age". Each complete cycle of phases is called a "Lunation". Since the cycle of the phases is shorter than most calendar months, the phase of the Moon at the very beginning of the month usually repeats at the very end of the month. When there are two Full Moons in a month (which occurs, on average, every 2.7 years), the second one is often called a "Blue Moon". This is where the phrase "Once in a Blue Moon" comes from.


Although Full Moons occur each month at a specific date and time, the Moon's disk may appear to be full for several nights in a row if it is clear. This is because the percentage of the Moon's disk that appears illuminated changes very slowly around the time of Full Moon. The same is true of a New Moon when the Moon is not visible at all. The Moon may appear 100% illuminated only on the night closest to the time of exact Full Moon. The nights before and after it will appear 97-99% illuminated and most people will not notice the difference. Even two days from a Full Moon the Moon's disk is 93-97% illuminated.


The primary phases of the Moon, New Moon, First Quarter, Full Moon, and Last Quarter, are defined to occur when the excess of the apparent ecliptic (celestial) longitude of the Moon over that of the Sun is 0, 90, 180, and 270 degrees. These definitions are used when the dates and times of the phases are computed for almanacs, calendars, etc.
