Friday the 13th is considered an unlucky day in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday, which happens at least once every year but can occur up to three times in the same year. In October 2023, Friday the 13th falls on the 13th of the month. However, there is no logical reason to fear the occasional coincidence of any day and date governed by the 400-year cycle of the Gregorian calendar.

There are many theories about the origins of the superstition surrounding Friday the 13th, but it is difficult to pinpoint the precise origins of it. Both Friday and the number 13 have been regarded as unlucky in certain cultures throughout history. In pagan times, Friday was believed to have a unique association with the divine feminine.

There are no specific events or activities that are happening on Friday the 13th, but some people may choose to avoid certain activities or stay at home due to the superstition surrounding the day. However, there are some Friday the 13th events happening in Los Angeles, California, such as a Latin party and tattoo sessions.
