As November 13, 2026, falls on a Friday, many Americans approach the date with a sense of foreboding. However, for numerous Cubans, the date synonymous with bad luck is not Friday, but rather Tuesday the 13th.
What explains the differing superstitions between such geographically close nations? The answer lies in the distinct cultural traditions each society has inherited over time.
While Friday the 13th looms large in the American psyche, in Cuba and other Spanish-speaking countries, there is a popular saying: "On Tuesday the 13th, don't get married, don't set sail, and don't stray from family."
The Significance of Tuesday the 13th in Cuban Culture
The fear surrounding Tuesday the 13th in Cuban culture is a tradition that has its roots in Spain and other Latin American countries. One popular theory ties the name Tuesday to Mars, the Roman god of war, linking the day symbolically to conflict, violence, or misfortune.
The number 13 adds another layer to the superstition. In Western Christian tradition, it is often associated with the Last Supper, where Jesus dined with his twelve apostles, including Judas. However, none of these associations scientifically prove that any specific date can bring bad luck.
The saying about avoiding marriage or travel on Tuesday serves as a caution passed down through generations. For those raised hearing this advice, it may seem more familiar than the tales of Friday the 13th popularized by American cinema.
Friday the 13th: An American Superstition
In the United States, Friday the 13th is the day that embodies the fears that much of the Hispanic world associates with Tuesday. Traditional explanations point to the crucifixion of Jesus on a Friday, combined with the already negative connotations of the number 13.
This belief gained traction through literature and entertainment. Thomas W. Lawson's novel "Friday, the Thirteenth," published in 1907, featured the date prominently in its plot. Decades later, the horror film "Friday the 13th," directed by Sean S. Cunningham and released in 1980, further cemented this superstition in popular culture.
Cultural Intersections for Cubans in the U.S.
Cubans living in the U.S. experience both traditions in their daily lives: the familial saying of Tuesday the 13th and the cinematic and conversational presence of Friday the 13th. These dates are not inherently dangerous but rather illustrate how beliefs evolve based on cultural surroundings.
This week, the National Autonomous University of Mexico reminded the public that there is no evidence linking Friday the 13th to disasters, nor a singular event explaining its origin.
In 2026, there were two Tuesday the 13ths, in January and October, and three Friday the 13ths, in February, March, and November. Today marks the last Friday the 13th of the year.
