Necktie Day is celebrated worldwide on October 18, originating from Croatia, where the necktie's predecessor, the silk neckerchief, was first worn by Croatian soldiers during the Thirty Years' War. These neckerchiefs, known as cravats, gained popularity in France after catching the attention of Parisians, particularly when King Louis XIV adopted the lace version. By the mid-19th century, cravats evolved into the modern necktie, becoming a fashionable accessory in Britain, where English gentlemen mastered numerous tie knots. Although Necktie Day is most prominently observed in Croatia, the United Kingdom, and France, festive events are also held in major cities around the globe, celebrating this iconic garment.
