October will end with a rare full moon on Halloween, called the blue hunter's moon.
The moon won't actually look blue, rather, the "blue" name means it's the second full moon in one month. This happens every 2.5 to three years, or "once in a blue moon."
Typically, when a moon does take on a bluish hue, it is because of smoke or dust particles in the atmosphere, such as during a major volcanic eruption.
When the phrase "once in a blue moon" was coined, it meant something so rare you'd be lucky (or unlucky) to see in your lifetime, according to NASA.
So if anything unusual happens to you on Halloween, there might just be a good reason why.
The end of Daylight Saving Time means an earlier sunrise and an extra hour of sleep.
Halloween will also be extra chilly, so if you are planning on spending any time outside, bring a jacket. Temperatures will be in the 50s for most of the day.
In 1887 the Triangle reportedly saw a trace of snow on Halloween.
