Icelandic National Day is celebrated on June 17, 2025. The day is a holiday in Iceland and celebrates the day in 1944 that The Republic of Iceland was formed. The date of 17 June was chosen because it is the birthday of Jón Sigurðsson, a major figure of Icelandic culture and the leader of the 19th century Icelandic independence movement.
