Galician Literature Day is observed in Spain, specifically in the autonomous community of Galicia, every May 17. This cultural observance celebrates the Galician language and its literature, having been instituted by the Royal Galician Academy in 1963. The date commemorates the publication of Rosalía de Castro's first poetry collection, "Cantares gallegos," in 1863, marking a significant moment in the 19th-century literary movement known as the Rexurdimento (Resurgence or Renaissance). Each year, the holiday honors a specific writer in Galician literature, chosen by the Royal Galician Academy from authors who have been deceased for at least a decade. The Galician language, an official language in Galicia alongside Spanish, is regulated by the Royal Galician Academy, based in A Coruña.
