This Friday falls on the 13th of the month and, for some, it will also be a full “Harvest” moon. While that doesn’t mean anything scientifically, it is a perfect storm for the superstitious.

The Harvest Moon is the full moon closest to the autumnal equinox, and for many people it will technically begin just after midnight on Saturday the 14th. But for those of us in the Pacific, Mountain, or Central time zones, it will start on Friday the 13th, according to the Farmers’ Almanac.

If you live in the Eastern Time Zone, the moment the Moon turns full will occur just after midnight—at 12:33 a.m. on Saturday, the 14th. But if you live elsewhere in the country—in the Central, Mountain, or Pacific time zones—the moment that the Moon turns full comes before midnight on Friday, the 13th!… It has been calculated that to have a full Moon occur on the 13th day of a particular month, and for that day to be a Friday, it is (on average) a once in 20-year occurrence!

This information has also been confirmed by NASA.

An average once-per-20-years coincidence is certainly interesting, but that doesn’t mean it has never been seen. In fact, there was a full moon on Friday the 13th in 2014. Still, that hasn’t stopped some people from completely freaking out.

One “article,” for instance, insists that “spooky things” will undoubtedly occur on the date.

Places like Wisconsin will be quite lucky in being able to see this interesting Friday the 13th full moon and there is no doubt that spooky things will be coming forth. Perhaps this is the best means of setting the proper mood for us all as we make our way through September and into October, the month of Halloween… Because the energies of this full moon are going to be quite intense, the idea of it falling on a Friday the 13th for some might be quite overwhelming but it is nothing to be concerned about. While a bit eerie it is actually a positive change for the mysterious date itself. The full moon can and will help to negate some of the more peculiar energies the 13th might be bringing forth.

The concern among the superstitious has also spread to Twitter.

Another Twitter user took the superstitions to another level, by looping in Astrological principles.

Maybe thoughts and prayers can help?

Some are even trying to cash in on the event:

What a beautiful and healing gift idea. Perfect for the full moon this Friday the 13th.#ClearingKit #meditatehttps://t.co/3ks0NAXUzy — Spiritual Journey (@SpiritualLeap) September 6, 2019

The coincidence is pretty interesting, and can be a good source for jokes, but it does appear that many superstitious people are taking it too seriously. For those who believe the hype, look into the science: neither the date nor the fullness of the moon affect our personality traits or bring “luck” of any kind.
