Galician Literature Day (Día das Letras Galegas) is a public holiday in the autonomous community of Galicia, Spain, on May the 17th each year.
It is also known as Day of Galician Literature or the Day of Galician Letters. It marks the anniversary of the publication in the Galician language of the literary work Cantares gallegos published in Havana, Cuba on May 17th, 1863 by the Galician writer and poet Rosalía Castro de Murguía, also known as Rosalía de Castro.
The publication of this work marked the start of the cultural renaissance of the Galician language, known as the Rexurdimento. The first Galician Literature Day was held on May 17, 1963. The Royal Galician Academy annually honours a Galician language writer.
This year 2011 is dedicated to Lois Pereiro.
