National Guy Day – June 29, 2025

National Guy Day is observed every June 29. It may not be a conventional holiday, but we think it’s an excellent way to celebrate all the great Guys out there! The name ‘Guy’ is derived from the Italian and Germanic ‘Guido,’ which was taken from the Old French ‘gui’ (‘guide’). ‘Guy’ may also be an anglicization of the Hebrew ‘Gai,’ meaning ‘ravine.’ The patron saint of comedians and dancers, St. Vitus, was also known as St. Guy. Guy is a popular name in the United States, and there have been many famous Guys, like Guy Fawkes and Guy Ritchie, throughout history.

History of National Guy Day

Guy was a popular name in the U.S. during the 1950s. It comes from the proto-Germanic ‘widuz,’ meaning ‘wood,’ and eventually developed to ‘wido.’ The Italians then borrowed and transformed the word into the Italian version, ‘Guido.’

The Italian language is from a family of languages known as the Indo-European language family. It evolved from Vulgar Latin and spread throughout the Roman Empire. In the Italian peninsula, dialects of Vulgar Latin were spoken. These dialects went on to be considered sister languages of Italian. The standard Italian spoken today can be traced back to 12th-century Tuscan and Sicilian poetry, which evolved from these sister dialects to the language used in official court proceedings during the Renaissance. Italy’s unification in the 19th century turned Italian into a commonly spoken language, even among the bourgeoisie.

Today, the language is spoken across the European continent. It is an official language of Italy and San Marino, spoken in Switzerland, and used in all Vatican City’s official state proceedings and documentation. It’s even used in Monaco, France, Montenegro, Malta, Slovenia, Croatia, Albania, the United States, and Australia because of past annexation and immigration.
