What myth? The current usage of "Blue Moon" may be based on a 50-year old misunderstanding of earlier (but similar) uses, but language evolves as often through mistakes or misunderstandings as it does by any other mechanism. The point is, that is the current usage, and there's nothing wrong with it. There is certainly no myth. By modern definition, a Blue Moon is just what this APOD says it is: the second full Moon in a calendar month.

I am also very disappointed to see the incorrect use of the term "Blue Moon"here on APOD. While language may evolve, definitions should not. A Blue Moon is the third Full Moon in a season that has four full moons. Period. Otherwise, they aren't rare - for example; both January and March of 2018 have two full moons. Hardly a rarity.

<<In the modern system of "traditional" full moon names tied to the solstice and equinox points, a supernumerary full moon in such a period is called a blue moon. The term "blue moon" used in this sense may date to as early as the 16th century, but it became well known in the United States due to the Farmers' Almanac (published since 1818).

According to the Farmers' Almanac, a "blue moon" is the third full moon in any period between either solstice and equinox, or between equinox and solstice, (calculated using the mean tropical year), which contains four full moons. These seasons are equal in length, unlike the astronomical ones, which vary in length depending on the Earth's speed in its elliptical orbit round the sun. To compare, in 1983 the equal length seasons began at 1.48 AM on 23 March, 9.15 AM on 22 June, 4.42 PM on 21 September and 12.10 AM on 22 December, while the astronomical seasons began at 4.39 AM on 21 March, 11.09 PM on 21 June, 2.42 PM on 23 September and 10.30 AM on 22 December (all times GMT). Due to a misinterpretation of this definition in the March 1946 Sky & Telescope magazine, "blue moon" has also been used in the sense of "the second full moon in any month which contains two full moons (this usage has been noted as "erroneous" by Sky & Telescope in 1999). According to either definition, "blue moons" occur with the average frequency of intercalary months, seven times in 19 years, the Farmers' Almanac system of "full moon names" effectively defining a lunisolar calendar.>>

Well, it's a blue-haired Moon. You can see the Lady in the Moon here. The hair above her forehead is reddish - see today's APOD - but the hair over her temple in front of her ear is bluish. Again, see today's APOD.

The Moon is an old blue-haired lady!

Ooops, that hair is violet, and the lady is Dame Edna!

<<Dame Edna is a character created and played by Australian dadaist performer and comedian, Barry Humphries, famous for her lilac-coloured or "wisteria hue" hair and cat eye glasses or "face furniture," her favourite flower, the gladiola ("gladdies") and her boisterous greeting: "Hello Possums!" Edna was born Edna May Beazley in the city of Wagga Wagga. Everage started her stage career on 19 December 1955 as Mrs. Norm Everage, an "average Australian housewife" from Moonee Ponds. Edna adopted an increasingly outlandish wardrobe after being performed in London in the 1960s, and grew in stature and popularity. Following film appearances and an elevation to damehood in the 1970s, the character evolved to "Housewife and Superstar", then "Megastar" and finally "Gigastar".>>

<<Blue Moon Belgian White, a Belgian-style witbier brewed in Golden, Colorado, was launched in 1995. MillerCoors does not actively advertise the fact that the brew is owned by MillerCoors, instead focusing on the Blue Moon Brewing Co. "

Witbier, white beer, bière blanche, or simply witte is a barley/wheat, top-fermented beer brewed mainly in Belgium and the Netherlands. It gets its name due to suspended yeast and wheat proteins which cause the beer to look hazy, or white, when cold. It is a descendant from those medieval beers which were not brewed with hops, but instead flavoured and preserved with a blend of spices and other plants referred to as "gruit". It therefore still uses gruit, although nowadays the gruit consists mainly of coriander, orange, bitter orange, and hops. The taste is therefore only slightly hoppy.

Some weiss and hefeweizen beers are commonly served with a slice of lemon in North America. Blue Moon is traditionally served with a slice of orange, which its brew masters claim accentuates the flavor of the brew.

In addition to their original Belgian White variety, Blue Moon Brewing Company offers Blue Moon Summer Ale, renamed Honey Moon in 2006. According to the bottle, "This ale beer is brewed with clover honey, orange peel, pale malt, and malted white wheat."

During the autumn months, Blue Moon provides Harvest Moon in 2007. This variety contains the flavors of pumpkins and other autumnal spices.

Blue Moon offers Full Moon with the subtitle "Blue Moon Winter Ale" in 2007.

In spring, Blue Moon provides Rising Moon.

It addition to its seasonal brews, Blue Moon released a pale ale called Pale Moon in 2008.>>

• Precisely!

<<Blue moon is the appearance of the third full moon in a season with four full moons. It is never really blue. The average lunar cycle is 29.530589 days, there are 365 days in a solar year, 365 divided by 29.530589 days equals about 12.36 lunar cycles in a solar year. In the gregorian calendric cycle, there are 12 months (the word month is derived from moon). In addition to those twelve months representing full lunar cycles, each solar calendar year contains roughly eleven days more than the lunar year of 12 lunations. The extra days accumulate, so every two or three years (7 times in the 19-year Metonic cycle), there is an extra full moon. Lunisolar calendars have rules about when to insert such an intercalary or embolismic ("leap") month, and what name it is given; e.g. in the Hebrew calendar the month Adar is duplicated. The term "blue moon" comes from folklore. Different traditions and conventions place the extra "blue" full moon at different times in the year. In the Hindu calendar, this extra month is called 'Adhik (extra) masa (month)'. It is also known as purushottam maas, so as to give it a devotional name.

In calculating the dates for Lent and Easter, the Clergy identify the Lent Moon. It is thought that historically when the moon's timing was too early, they named an earlier moon as a "betrayer moon" (belewe moon), thus the Lent moon came at its expected time.

Folklore gave each moon a name according to its time of year. A moon that came too early had no folk name, and was called a blue moon, retaining the correct seasonal timings for future moons.

The Maine Farmers' Almanac defined a "blue moon" as an extra full moon that occurred in a season; one season was normally three full moons. If a season had four full moons, then the third full moon was named a "blue moon".>>
