Full harvest moon will bring spooky sight to the skies on Friday the 13th

Get ready for a frightful sight this Friday the 13th.

According to the Farmers' Almanac, a full moon will glow ominously in the night sky late Friday over much of the U.S., except in the Eastern time zone, where the moon won't technically be full until 12:33 a.m. Saturday.

Superstitious skygazers flocked to social media ahead of the celestial display, which comes on a date widely considered bad luck in Western culture. The reason? In Christianity, the Last Supper's 13th guest, Judas, betrayed Jesus, who was crucified on a Friday, Connecticut College psychology professor Stuart Vyse told National Geographic in 2013. Eventually, those worries spread, according to the magazine.

In case y’all don’t know, next Friday is not only Friday the 13th but also a full moon. 🌝🙃 Teachers, prepare ourselves.

The good news? You'll have decades to prepare for the next Friday the 13th full moon, which will come Aug. 13, 2049, the Farmers' Almanac reported.

This weekend's lunar display is also the harvest moon, or "the full moon nearest to the autumnal equinox," according to the almanac. In addition, it is considered a "micro moon," which means it will look 14% smaller than usual, the almanac reported.
