Constitution Day is observed in the Marshall Islands every May 1, commemorating the adoption of the 1979 Constitution that established the archipelago as a self-governing country. This national holiday marks the country's journey towards independence, following a referendum in 1978 where the majority supported self-governance. Celebrations typically include festive parades and sporting competitions, highlighting the significance of independence for the Marshallese people. The Constitution set up a mixed parliamentary-presidential system, with the President serving as both head of state and head of government, elected by the Nitijela, the parliament of the Marshall Islands. As the most important holiday in the country, Constitution Day reflects the pride and unity of the Marshall Islands' citizens.
