The night sky on Halloween will be illuminated by the blue moon, the second full moon in a month. According to NASA’s National Space Science Data Center, the breasts occur at a relatively low rate once every two years.
Each month has a full moon, but because lunar cycles and calendar years are not completely synchronous, almost every three years we end up with two in the same calendar month.
The first full moon of October, also called the harvest moon, will appear on the first day of the month. The second full moon, or blue moon, will appear on October 31. This is the first instance of a blue moon in the United States since March 2018.
According to Farmers Almanac, this is the first Halloween full moon since 1944. The last time Halloween’s full moon was published was in 2001 for the Central and Pacific time zones.
The “once in a blue moon” phenomenon does not necessarily mean that the moon will appear blue on Halloween. Although the dark blue color of an evening sky may affect the color of our vision, the Earth’s satellite may not appear blue.
Typically, when a moon turns blue, it is caused by smoke or dust particles in the atmosphere, such as during a large volcanic eruption.
When “once a sentence in the blue moon” was created, it meant that you would be very lucky (or unlucky) in your lifetime, according to NASA.
So if something weird happens to you on Halloween, there’s a good reason for it.
