Why is Friday the 13th considered unlucky?

There are a number of theories around why Friday the 13th is considered such an unlucky date.

Most Popular

    One of the most popular ones regarding the superstition connects the date of Friday the 13th with the demise of the Knights Templar.

    Hundreds of Knights Templar were arrested on Friday 13 October, 1307, by King Philip IV of France.

    History states: “Founded around 1118 as a monastic military order devoted to the protection of pilgrims traveling to the Holy Land following the Christian capture of Jerusalem during the First Crusade, the Knights Templar quickly became one of the richest and most influential groups of the Middle Ages, thanks to lavish donations from the crowned heads of Europe, eager to curry favor with the fierce Knights.

    “By the turn of the 14th century, the Templars had established a system of castles, churches and banks throughout Western Europe. And it was this astonishing wealth that would lead to their downfall.”

    In a bid to overtake the money, land and power from the Knights Templar, King Philip IV of France ordered their arrest.

    The Knights Templar were brutally tortured, kept in isolation and fed only scraps and water.

    What are some other theories?

    Another popular theory regarding the unluckiness of Friday the 13th is attributed to the story of Jesus’s last supper, and his crucifixion. Leonardo da Vinci’s painting of the Last Supper presents 13 people in the Upper Room on the 13th of Nisan Maundy Thursday, the night prior to Jesus’s death on Good Friday.

    Judas, who betrayed Jesus, is also thought to have been the 13th guest to sit at the table.

    Additionally, the connotations of Friday the 13th being unlucky could be traced back to a novel by Thomas W Lawson called Friday, the Thirteenth, which was published in 1907.

    The story tells the tale of a banker who uses the superstition around Friday the 13th to create a Wall Street panic on that very date.

    In the 1869 biography of Italian composer Gioachino Rossini, who died on Friday 13 November, by Henry Sutherland, it is documented that the composer regarded Friday as an unlucky day, and the 13th as an unlucky number.
