A rare type of full Moon will soon grace the sky that coincides with a spooky date: Friday the 13th.
The so-called “harvest moon,” which is the full moon nearest to the start of fall, or the autumnal equinox, will be seen in the U.S. on Friday in the Central, Mountain and Pacific time zones, according to the Farmers Almanac.
For those in the Eastern time zone, they can still get a glimpse of the moon but it will be seen after midnight, at 12:33 a.m., on Saturday.

The last nationwide full moon on Friday the 13th happened on Oct. 13, 2000. It's not expected to happen again until August 13, 2049.
Twitter users were quick to point out the eerie connection between the full moon and Friday the 13th, but the experts were quick to point out "there's no need to worry."
"A full Moon just means that we can see the half of the Moon that is facing the Sun," NASA Moon tweeted. "There’s always a full Moon somewhere in space! It’s just your perspective."
And while the upcoming moon is a full one, its size will actually be quite small.

“Harvest Moon” got its name after it allowed farmers to harvest their summer crops during the early evening thanks to the ample amount of bright moonlight that came through.
