The Blue Moon is known as a rare and powerful celestial event and has significance in offering clarity and insight into what is blocking us from our goals.

Blue Moon represents a time for closure and reflection on intentions set during the previous lunar cycle.
It is a potent time for manifestation, as there is an amplification of energy and motivation.
This period allows for deep spiritual growth, healing, and transformation.

The spiritual meaning of Blue Moon shifts us towards taking responsibility for our own lives and making the most of our potential.

As the second Full Moon in a calendar month, it is an excellent time for reflection and completing unfinished business, both physically and spiritually.

It is an invitation to let go of what no longer serves us and take proactive steps toward a happier, healthier, and more fulfilling life.

What is a blue moon?

Cultures around the world, including the Native Americans, have given names to each of the full Moons, with each typically happening in its own month.

For example the ‘Wolf Moon’ is usually the full Moon occurring within January. With the cycle of the phases of the Moon lasting approximately one month, and there being 12 months in a year, we typically have 12 full moons each year.

However, the phases of the Moon actually take 29.5 days to complete, meaning 354 days total for 12 full cycles. This falls some way short of the 365/366 days in a calendar year: therefore, roughly every two and a half years a 13th full moon is seen. This additional full moon does not fit with the normal naming scheme and so is instead referred to as a ‘blue moon’.

Traditional definition of a blue moon

Which of the 13 full moons is the blue moon is up for debate. Traditionally the definition of a blue moon is the third full Moon in an astronomical season containing four full moons. This is the most complicated definition for people using the standard calendar, as the astronomical seasons begin and end at the equinoxes and solstices (e.g. the winter season begins at the winter solstice and ends at the spring equinox, the spring season begins at the spring equinox and ends at the summer solstice and so on).

The second (mistaken) definition of a blue moon

Another definition of the blue moon, perhaps the more commonly used due to its simplicity, is actually a mistake, made in the 1940s and perpetuated by radio shows and the Trivial Pursuit board game through the 1980s. This definition describes the blue moon as the second full Moon in any calendar month with two full moons. As February 2018 had no full moon in it, both January and March ended up with two full moons, so by this definition both months contained blue moons. Interestingly though, by both definitions not everywhere in the world experienced the same number or position of blue moons in a year due to different parts of the globe having different timezones but the Moon having only one moment in time when it is full.

Quite where the term blue moon came from is unclear. It may be a mispronunciation of the disused word “belewe” which means ‘to betray’. This may be a reference to the betrayal of the usual idea of having one full moon in each month or perhaps the “betrayal” by the Moon of worshippers attempting to determine the position and duration of Lent in the calendar year.

When is the next blue moon? 

As this Moon is also a supermoon, it will be a Super Blue Moon. 

Future blue moon dates:

What colour is a blue moon?

Blue moons aren’t blue! Blue moons remain the same colour as any other full moon except in two rare cases. During a lunar eclipse, the Moon can turn blood red, lit only by the light that is bent around the Earth by its atmosphere onto the face of the Moon. As lunar eclipses occur only during full moons, and blue moons are one type of full moon, very rarely a blue moon will be red!

In very rare circumstances, the Moon can appear blue, but in this case it is a colour added to the Moon by viewing it through a haze of dust particles in our atmosphere, perhaps from a recent volcanic eruption. In this case, from space, the Moon will look just as grey as it always has!
