Friday the 13th is considered an unlucky day with roots in religious contexts and cultural phenomena. This superstition is likely to have originated in the Christian religion, as the number 13 is associated with unfortunate events in the Bible, such as Judas being the 13th guest at the Last Supper and several other misfortunes occurring on Fridays. Norse mythology also contributes to this belief with a story of mischief and chaos associated with the number 13.

Fast food chains Krispy Kreme and Wendy’s are offering deals to help ease superstitions surrounding Friday the 13th. Customers can use the promo code “13” to access a buy-one-get-one deal on dozens of donuts, limited to one 13-cent dozen per customer. Additionally, customers can enjoy a small Frosty for $1 until the end of the month.

This superstition has been reinforced by literature, films, and popular culture, such as the 1980 horror film *Friday the 13th*, which helped popularize the day as a harbinger of doom and bad luck. In 2024, Friday the 13th will occur twice, in September and December.
