🇮🇹 Italy

Thirteen was traditionally tied to abundance — hitting all thirteen matches in the Totocalcio football pool is called fare tredici, meaning to strike it rich. That said, global culture has made 13 a debated number, and some Italians now avoid it too.

Rearrange the Roman numeral XVII and you get VIXI — Latin for I have lived, in other words, I am dead. Friday the 17th is Italy's unlucky day, and some planes and hotels skip row or room 17.
