National and International Days on March 12

National Alfred Hitchcock Day: This day celebrates the life and legacy of Alfred Hitchcock, the master of suspense. Known for blending suspense with humor, psychological complexity, and voyeuristic storytelling, Hitchcock’s career spanned multiple eras, including the silent period, British productions, and his most famous Hollywood films of the 1950s and 1960s. Though the reason for March 12 as the chosen date is unclear, it remains a fitting occasion to revisit his legendary films and their lasting impact on cinema.

National Baked Scallops Day: This day highlights one of the most beloved seafood dishes—baked scallops. Though scallops were not widely appreciated in America until the 19th century, they have since become a staple in fine dining. Scallop recipes gained popularity through the early 20th century, with dishes like Coquille St. Jacques elevating the shellfish to gourmet status. Whether baked with butter, herbs, and breadcrumbs or served in a creamy sauce, this dish continues to be a favorite among seafood lovers.

National Girl Scout Day: March 12 marks the anniversary of the founding of the Girl Scouts of the USA by Juliette Gordon Low in 1912. Starting with just 18 girls in Savannah, Georgia, the organization has grown to millions of members worldwide. This day honors the contributions of Girl Scouts in fostering leadership, service, and adventure for young girls.
