Rare full moon on Halloween and an extra hour of sleep

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."

CNN reports a full moon on Halloween is extremely rare -- an event that hasn't occurred across time zones since 1944.

A full moon occurs on Halloween every 19 years in some time zones, so you can expect a full Halloween moon again in 2039, 2058, 2077 and 2096.

Full moon on Halloween only occurs every 19 years.

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 full Halloween moon will rise at 6:39 p.m. ET on Oct. 31. Halloween is also the last day of Daylight Saving Time, so set your clocks back one hour on Nov. 1 at 2 a.m.

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.

The coldest Halloween we've ever seen in the Triangle was in 1963, where we saw temps as low as 30 degrees. The warmest Halloween was last year's, where we felt temps as warm as 85 degrees -- yuck.

In 1887 the Triangle reportedly saw a trace of snow on Halloween.
