Months! A blue moon is when there are 2 full moons in 1 month.
Almost every anime series
Blue Moons aren't like solar eclipses - they don't just happen to a certain part of the Earth. A blue moon is just the name for the event where a full moon happens twice in the same month; The second full moon in that month is called a "blue moon". You can see the moon from anywhere on the Earth in a 24 hour period, so yes, the next blue moon will happen "over" the US.
You mean like a Harvest Moon, or a Blue Moon? There are certainly Moons which appear yellow enough to be called "golden" but that's a matter of individual discretion; "Golden Moon" is not an "official" Moon on any of the lists.

A blue moon happens about once every 19 years. When this happens, there isn't a full moon in February which puts two full moons in two other months.
There are 720 full moons in 60 years. Not counting Blue moons, Red moons or any other type
AstronomyA "blue moon" is the second full moon to occur in a calendar month. It happens rarely, hence the phrase, "Once in a blue moon." Because full moons occur every 29.5 days, a second full moon can occur if the first one is early enough in a month.Since a year has 11 days more than the 12 lunar months, the extra days accumulate, so that every two or three years (on average about every 2.7154 years) there is an extra full moon. The extra moon is also called a "blue moon".The original use of the term blue moon was by the Farmers Almanac, to mean the third of four full moons in a "season." This nomenclature allowed the final full moon to be used in various seasonal calculations.Hypothetical PlanetAurelia and Blue Moon are hypothetical examples of a planet and a moon on which extraterrestrial life could evolve. The fictional satellite, called Blue Moon, of a hypothetical planet (Aurelia) was an exercise underwritten by National Geographic.(see related links)
I don't know for gray and yellow but for blue... The moon is only blue every 10 years or something. The reference is called "once in a blue moon" which means it's a really long time. The moon is only blue when there are two full moons in one month. That's 28 days. Blue moons can last up to a week.
No more then any other full moon. A blue moon is just the second full moon in any one month. It happens about every 3 years hence the old saying once in a blue moon.
The term "Blue Moon" refers to the second full moon in any single month, so.. if you have a full moon on the 1st, 2nd or 3rd (in months with 31 days) you will have a "blue moon" 28 days later. The event itself is a rarity, thus the phase "once in a blue moon". Blue moons happen approximately every 2.5 years. The last New Year's Eve blue moon was in 1990. The next will be in 2028. Fortunately for New Year's Eve revelers, full moons are also known for stirring up emotions and sparking wild revelry. So be sure to look up and raise your glass as you ring in 2010.

A "blue moon" has been defined as two full moons in the same month. This can happen in any month except in February. It isn't all that rare; it happens about every other year.Two "blue moons" in the same year can only happen in January and March, which is what happens in 2018. That's because February is the only month in which it's possible to NOT have ANY full moons; February has only 28 days, and a month is 28.5 days!We can expect this (two "blue moons" in the same year) about every 31 years; any time the Moon is full on January 2, it will be full again on January 31, March 2 and March 31.
Once in a blue moon has come to mean once in a great while, but the actual frequency of blue moons averages about once every 2.7 years, a blue moon being the second full moon in the same month of a solar calendar. That average frequency is exactly the same as the average frequency of a leap month in a lunar calendar. The calculation of the average frequency of blue moons does not take into account that January and March of 2018 will EACH have two full moons, a rarity caused by the fact that February does not last as long as a lunar cycle.
When a single month has two full moons, the second full moon is called a Blue Moon. It happens every 2-3 years. Originally, the Maine Farmer's Almanac defined a "blue moon" as the 13th moon in a tropical year(from winter solstice to winter solstice). Normally, each season would consist of 3 moons. In a season of 4 moons, the third would be considered blue. Blue ink was used to record this event in the almanac. As a reference to the event, though, the idiom "once in a blue moon" means rarely. There is no set amount of time.
There are blue moons, but there are not known green moons.
Once in a blue moon! Well that is what the second full moon in a month is called, a blue moon. It is very irregular, sometimes it can happen multiple times a year or even two months in a row. Other times it can be years between them.
