Blue Moon in 2021 year
The second full moon of the month in astronomy is called the Blue Moon, which is not due to the satellite's shade, but to the idiom in English - "Once in a Blue Moon", which translates as "Once Upon a Blue Moon" and is equivalent to "After the rain on Thursday". This phenomenon occurs every 3-4 years, when the date of one of the full moons falls at the beginning of the calendar month, and the subsequent one comes just before the end of the same month. Usually in the year there are 12 full moons and each has its own name, the Blue Moon was named the 13th full moon, which sometimes happens in some years.
In fact, in rare cases, the moon can acquire a bluish tinge. For example, on cold winter nights, when ice crystals in the air form a halo around the moon, there is a scattering of moonlight, which causes such an effect (the light of the blue part of the spectrum dissipates much better in the atmosphere in red).
Also, an unusual shade of the moon may appear as a result of a volcanic eruption - for example, in 1883 there was an eruption of the Indonesian Krakatoa volcano, which was so powerful that the ash columns rose to the upper part of the atmosphere. Ashes particles absorbed waves of the red part of the spectrum, which led to the fact that the moon for several years seemed blue (sometimes - green). Volcanologist Scott Rowland of the University of Hawaii said that the sun was then lavender-colored, and the sunsets were so bright red that people in New York and some other cities called firefighters, suggesting a fire.
One way or another, it is the rarity of such events (two full moons in one month, the moon of a bluish tinge) gave rise to the English saying "Once at the Blue Moon" - something that happens very rarely. City Havana.

Overall forecast
"Blue Moon" refers to the second full moon, occurring for one calendar month. The name is due not to a change in the color of the Moon, but to the idiomatic expression "Once in a Blue Moon", borrowed from the English language, which literally translates as "Once Upon a Blue Moon," and one of the values is equivalent to the Russian expression "After the Rain on Thursday" (i.e., very rarely, or never). The full moon itself has an ordinary, ash-gray color; the appearance of a blue shade in the moon is an extremely rare phenomenon due to the optical effect. This event occurs once every 2 or 3 years.
In fact, the Blue Moon will indeed awaken in us immediate actions to change the course of life. Within four days you will probably be able to see new opportunities or, at least, think about what does not suit you. Perhaps, the solution you need is very unexpected and not at all, as you could imagine.
Sometimes the comfort zone can play a cruel joke. Until then, it can be convenient, but sooner or later it becomes exhausting and keeps from very important steps, does not let us know who we really are.
The Blue Moon contributes to the exit from the comfort zone and allows you to experience life with all its pluses and minuses. She opens her eyes to us. In order to really see new opportunities, we must trust the universe and swim along with the flow of its energies.
