Every March 21, Tiramisu Day celebrates one of the most beloved Italian desserts, which consists of coffee, mascarpone cheese, and cocoa. Various narratives exist regarding the dessert's origins, but major Italian institutions pinpoint its modern version to Treviso, Veneto, where it is said to have originated in the 1970s at the restaurant Le Beccherie, thanks to Ada Campeol and chef Paolo 'Loli' Linguanotto. Tiramisu has gained immense popularity and is enjoyed worldwide.

Along with its culinary significance, the date of March 21 has become associated with Tiramisu Day through publications related to the Tiramisu World Cup, showcasing the dessert's cultural importance and its variations.
