Portugal Day, also known as the Day of Camões, is observed annually on June 10 in Portugal and among Portuguese communities worldwide. This holiday commemorates the death of the national literary icon Luís de Camões, who passed away on June 10, 1580. Camões is celebrated as the greatest poet of the Portuguese language, with his notable work, Os Lusíadas, recognized as Portugal's national epic poem that honors the country's history and achievements. The observance of Portugal Day includes various parades, ceremonies, and concerts, with the President of the Portuguese Republic selecting a city each year to host the official celebration. Additionally, Portuguese diasporas in countries such as Canada, the UK, and the USA also organize their own festivities to mark the occasion.
