What is a blue moon and when will it happen?

Weather of Arabia - This year we will witness a distinct astronomical phenomenon, which is the "blue moon". Here is everything you need to know about this moon

"When the moon is blue" is a phrase used to describe a very rare event, but what does it mean in astrological terms? Can the moon really turn blue?

The truth is that there are two types of blue moons, but unfortunately; Neither of them have anything to do with blue

The blue moon has two types

Currently the second expression is used as a definition of a blue moon rather than being an erroneous definition.

Since the cycle of the moon phases is about a month long, we usually see 12 full moons each year . Many cultures have given distinct names to each month's full moon; Which means 12 months, 12 full moons, 12 distinct names. It sounds simple right?

Well, not exactly, this is where the blue moon comes into the equation.

The moon phases actually take 29.5 days to complete, which means it only takes 354 days to complete 12 lunar cycles, so every 2.5 years or so a 13th full moon is observed during a calendar year, and this 13th full moon does not correspond to the naming system. It is referred to as a blue moon.
