National Calzone Day Cards

National Calzone Day celebrates the calzone, an Italian oven-baked turnover originating in Naples in the 18th–19th century as a folded form of pizza. The holiday highlights the calzone's history, regional variations, and popularity as a portable, filled pizza alternative—featuring cheeses, meats, and vegetables sealed inside a pizza dough shell. Observers mark the day by enjoying calzones at pizzerias, trying homemade recipes, and exploring different styles and fillings.
