If anyone is trying to wake some dark spirits, tonight’s the night.
Halloween is here (Oct. 31), along with a full “blue moon” — meaning the second full moon in a single month. All Hallow’s Eve full moons are rare enough, occurring about once every 19 years. But this is the first time since 1944 that trick-or-treating has lined up with a blue moon, according to the Farmer’s Almanac.
The spooky lightshow in the sky should begin soon enough for even the earliest candy-hunters. Moonrise should happen between 5:50 and 6:40 p.m. local time across most of the United States, with some variance between different latitudes and positions within time zones. Right after moonrise, the moon should be visible at the horizon. As the night wears on, it will rise higher and shine brighter — illuminating any tricksters out egging houses (no, don’t do that!).
