There is one full moon in a lunar month. When thre is 2full moons in a calendar mont it is called a blue moon. Hence the saying once in a blue moon, not very often.

"Blue Moon" is when two full moons happen in one calendar month. Since the phase period of the moon is 29.5 days, you usually only have one full moon month, but each month it is a little earlier than the previous month. About once a year or so, you get two full moons in the same calendar month, and the second one is called the "blue moon". There is no physical difference or appearance difference of the moon at this time, it just looks like a regular full moon: circular and white with gray patches.

One in 7 months has a Friday on its 13th day.  One in 28 of those should have a full moon as well.  Therefore, assuming no other patterns that prohibit certain combinations, one in every 196 months should have both a Friday the 13th and a full moon on the same night.  Once every sixteen years or so.

The moon's distance from earth is about 240,000 miles.  The orbit is roughly circular (only 5% eccentricity), so 2π*240,000 = 1.5 million miles is the circumference.  The moon travels this distance in 29.5 days, so its speed is about 51,000 miles per day or about 2100 miles per hour.

Full moon\n\nThe Galileo spacecraft took this composite image on 7 December 1992 on its way to explore the Jupiter system in 1995-97. The color is 'enhanced' in the sense that the CCD camera is sensitive to near infrared wavelengths of light beyond human vision.The Full Moon is the lunar phase that occurs when the Moon lies on the opposite side of Earth from the Sun. The Moon as seen from the surface of Earth is fully illuminated by the Sun at this time, presenting a "full" round disk to viewers on Earth. As always, only half the total surface of the Moon is illuminated.\n\n\n1 Eclipses \n2 Numbers and formulae \n3 Folklore \n4 Calendars \n5 Full Moon names \n6 The Blue moon \n7 See also \n8 References \n \n\n\n\nEclipses\nA Full Moon is the only time when a lunar eclipse is possible; at that time the Moon may move through the shadow cast by Earth. However, because of the tilt or inclination of the Moon's orbit around Earth relative to Earth's orbit around the Sun, the Moon usually passes to the north or south of Earth's shadow at Full Moon, so a lunar eclipse does not occur at every Full Moon.\n\nFull Moons are generally a poor time to conduct astronomical observations, since the bright reflected sunlight from the Moon overwhelms the dimmer light from stars.\n\n\nNumbers and formulae\nAlthough on average it takes only 27.322 days (sidereal month) for the Moon to complete one orbit around Earth, it requires about two more days than that to again catch up with the Sun. On average, the number of days between Full Moons is about 29.5306 days. The actual number of days may differ from the average number by more than a half day. From one Full Moon to the next, the number of days in one lunation can vary between 29.272 and 29.833 days.\n\nThe age and apparent size of the Full Moon vary in a cycle of just under 14 synodic months, which is called the Full moon cycle.\n\nThe combined date and time of Full Moon number N, using a fictitious moon that moves at a strictly mean rate is approximately:\n\nD = 20.362954 + 29.5305888531 × N + 102.19 × 10-12 × N 2 \nD is the number of days (and fractions) since 1 January 2000 00:00:00 UTC, \nN is the count of full moons starting with zero as the first (not 1 as you would have expected) as the first Moon in the year 2000. \nThe true Full Moon may differ from this by up to about 14.5 hours, due to the normal irregularity in the Moon's Keplerian orbit, and due to the periodic perturbations on that Keplerian orbit by the Sun, the equatorial bulge of Earth, and nearby planets.\n\nSee the New Moon page for a detailed explanation of the formula.\n\n\nFolklore\nFull Moons are traditionally associated with temporal insomnia, insanity (hence the terms lunacy and lunatic) and various magical phenomena such as lycanthropy.\n\nPsychologists have found that there is no strong evidence for effects on behaviour around Full Moon [1]. They find that studies are not consistent, with some showing a positive effect, while others will show a negative effect. In one instance, the December 23, 2000 issue of the British Medical Journal published two studies on dog bite admission to hospitals in England and Australia. The study of the Bradford Royal Infirmary found that dog bites were twice as common at Full Moon, while the study of public hospitals in Australia found they were less likely at Full Moon. Psychologists point out that there is a difference between correlation and causation. The mere fact that two events happen at the same time doesn't mean that there is a cause and effect relationship between the two.\n\nNeopagans hold a monthly ritual called an Esbat at each Full Moon.\n\nMany people practicing traditional Chinese religions prepare their ritual offerings to their ancestors and deities on every Full Moon and New Moon.\n\n\nCalendars\nThe Islamic calendar and the traditional Chinese calendar are both based on the phases of the Moon. Neither calendar, however, begins i

A lunar eclipse is much slower than a solar eclipse when viewed from Earth. On average a lunar eclipse is visible from a point on earth for between 4 and 5 hours, a solar eclipse usually lasts 90 minutes.

The question is about the lunar sidereal period.  It is 27.32166 days, as a casual web search reveals.

On September 27 1977, the Moon was full. Exact full moon occurred at 08:29 UT. For astrological purposes, the Moon passed from Pisces into Aries at  00:40 UT on the 27th. The distance to the Moon was 60.65 earth radii at 0 hours UT and 61.24 earth radii at 24 hours UT.

It depends on how you define "orbit". \n\nIf you define orbit to mean the time it takes the Moon to come back to the same point with respect to the Sun (new moon to new moon), that is a synodic month, which is 29.53059 days.\n\nIf you define orbit to mean the time it takes the Moon to come back to the same point with respect to a fixed star, that is a sideral month, which is 27.32166 days.\n\nIf you define orbit to mean the time it takes the Moon to come back to the same point with respect to the intersection of the equator and ecliptic, that is a tropical month, which is 27.32158 days.\n\nIf you define orbit to mean the time it takes the Moon to come back to its perigee, that is an anomalistic month, which is 27.55455 days.\n\nIf you define orbit to mean the time it takes the Moon to return to its ecliptical ascending node, that is a draconic month, which is 27.21222 days.

sing songs of worship and praise to the goddess and all women in general. theirs is a hard life for the choice of having children. we must respect that. the full moon is the mother in her total glory and the new moon is her time of the month so to speak!  but the moon having a cycle of 28 days the same as a womans menstral cycle is why pagans always worshiped the moon as the mother goddess. full moons were and are today a witches excuse to party!

Probably not until 2025, in 19 years' time, because of the "Metonic cycle".\n\nThere are 235 lunar cycles in 19 calendar years, with an error of only 2 hours (see the website below).  Each year, the moon phases after 12 lunar cycles are 10 or 11 days out compared to the year before.  After 3 years and 37 lunar cycles, they are only 2 or 3 days out, but it never gets any closer until that magic 19 years when it is almost perfectly back in step.

It is a valid observation.  Ask anybody that works in a hospital or bar.  I used to work in a bar, so I know people are definitely different on a full moon.  The moon affects the water and tides.  Our bodies are made up of 2/3 water.  So we would be affected, too.

It takes the moon roughly 28 days to orbit the Earth.  Divide that into the number of minutes in a day (1440), and there's your 50 minutes.

The harvest moon is the full moon that occurs closest to the fall equinox (usually late September or early October).  It got its name because the full moon was so bright that farmers could continue working on their crops late into the night.

Nope it has to be 2 full moons.  Not 2 new moons.  There's only been one full moon this month.  there will be, however, two new moons.  one was on the 1st and the other will be the 31st....  the full moon happened on December 15th.\n\nA "Blue Moon" is the name given to the second full moon in a calendar month. Because there are roughly 29.5 days between full moons, it is unusual for two full moons to "fit" into a 30 or 31 day month (and impossible to fit into a 28 or 29 day month, so February can never have a Blue Moon). The saying "Once in a Blue Moon" means a rare occurrence, and predates the current astronomical use of the term, which is quite recent. In fact, Blue Moons are not all that rare, on average there will be one Blue Moon every 2.5 years. After 1999, the next Blue Moons will be in November 2001; July 2004; and June 2007. The last one before 1999 was in July 1996. \nThe term Blue Moon is believed to have originated in 1883 after the eruption of Krakatoa. The volcano put so much dust in the atmosphere that the Moon actually looked blue in color. This was so unusual that the term "once in a Blue Moon" was coined. However, Blue Moon was also used in much the same way we use the term "Harvest Moon". There were twelve names for full moons, one for each month, and the name Blue Moon was used in years which had 13 full moons. It referred to the third full moon of the four occuring between an equinox and solstice in that year. A misinterpretation of this led to a Sky and Telescope Magazine "Star Quiz" in July 1943 followed by an article in March 1946 which stated that the second full moon in any calendar month was called a Blue Moon (attributed to the 1937 Maine Farmers' Almanac), and this definition has now become part of the language. \n\nIn January and March of 1999, we had a situation which only takes place about four times a century: two Blue Moons occurring in the same year. The last time this happened was in January and April of 1961 and it will not happen again until January and March of 2018. A double Blue Moon most commonly occurs in January/March but is also possible in January/April or January/May and only when there is no full moon at all in February. It is also possible to have a Blue Moon in December of one year and March of the next year, again, there is no full moon in the intervening February. \n\nThat might have been way more info than you wanted, but now you know... and knowing is half the battle.
