Orkney Day, also known as the Feast Day of Saint Magnus of Orkney, is observed in the Orkney Islands, an archipelago off the north coast of mainland Scotland, every April 16. This day commemorates Saint Magnus Erlendsson, a notable ruler of Norwegian Orkney who was canonized in 1136 after his martyrdom on this date, although the exact year of his death is unclear. The celebration highlights the cultural heritage of the Orkney Islands and includes various religious observances in honor of Saint Magnus, whose relics were moved to Kirkwall, where a cathedral was built in his honor. Additionally, the annual St Magnus International Festival takes place every June, showcasing a week-long celebration of arts, including music, dance, drama, literature, and visual arts, further enriching the cultural landscape of Orkney.
