When is Sir Hammer DeRoburt Day?

In 2026, Sir Hammer DeRoburt Day falls on Friday, September 25, 2026. It is classified here as a paid public holiday.

History of Sir Hammer DeRoburt Day

Sir Hammer DeRoburt was born on September 25, 1922 and became a central leader in Nauru’s movement toward independence and control of its phosphate industry. He served as head chief, represented Nauruan demands internationally and became the republic’s first president in 1968.

His life also encompassed Nauru’s wartime trauma: he was among the Nauruans deported by Japanese forces to Truk, now Chuuk, during the Second World War. The annual date was formally named for him in 2020 while continuing youth activities formerly associated with September 25.

DeRoburt’s leadership should be placed in context rather than reduced to a heroic slogan. He represented Nauruan demands during the trusteeship era, rejected relocation proposals that lacked secure Nauruan land ownership, helped negotiate independence and phosphate control, and served repeatedly as president through politically unsettled years. Government made September 25 an annual holiday under his name in 2020, retaining youth activities connected with the date. Commemoration can recognise his public role while allowing historical assessment of decisions and institutions. Essential services remain rostered and private employment arrangements require separate confirmation. This Sir Hammer DeRoburt Day guide separates the verified public-service rule from broader social practice, so readers should use the current Gazette, employer directions and service notices for practical decisions.
