Friday the 13th has long been associated with bad luck in Western culture. For generations, many people have believed that this date brings misfortune. Although there is no single confirmed origin for the superstition, historians say it likely comes from a mix of older beliefs about the number 13 and the day Friday.
Why is the number 13 seen as unlucky?
The belief that the number 13 brings bad luck dates back centuries. One commonly cited explanation comes from the Bible. At the Last Supper, Judas Iscariot, the disciple who later betrayed Jesus, is often described as the 13th guest at the table. Because of this association, the number gradually gained a reputation for being unlucky.
Norse mythology also includes a similar story. In one legend, a dinner gathering of the gods was disrupted by an unexpected 13th guest, Loki. His arrival is said to have led to chaos and darkness. Stories like these helped strengthen the idea that having 13 people at a table could invite misfortune.

Even today, some people avoid the number in daily life. Many hotels skip room number 13, while some apartment buildings jump from the 12th floor directly to the 14th. Several airlines also avoid labeling a row as number 13.
Why Friday carries negative associations?
Friday itself has also been linked with unlucky events in some traditions. Biblical stories mention several significant events taking place on a Friday, including the beginning of the Great Flood and the day Adam and Eve are believed to have committed the first sin.
Historical writings also reflect this belief. Geoffrey Chaucer’s The Canterbury Tales, written in the 14th century, refers to Friday as a day connected with misfortune. In the United Kingdom, Friday was once called “Hangman’s Day,” because executions often took place on that day.

How the superstition developed?
Interestingly, the idea that Friday and the number 13 together bring bad luck appears to be relatively recent. An article published in a French literary magazine in 1834 mentioned the belief that both Friday and the number 13 are unlucky.
There is even a specific term for the fear of this date. It is called paraskevidekatriaphobia, which refers to the fear of Friday the 13th.
Despite the superstition, the day is not viewed negatively everywhere. In Islam, Friday is considered the holiest day of the week. In Judaism, Friday evening marks the beginning of Shabbat, the weekly day of rest.
