A cultural observance on March 24 celebrating the political union and commonwealth status of the Northern Mariana Islands with the United States as established by the 1976 Covenant.

The U.S. Congress approved the Covenant establishing the Northern Mariana Islands as a Commonwealth in Political Union with the United States via Public Law 94-241 on March 24, 1976, signed by President Gerald Ford. The anniversary was later formalized as a public holiday by CNMI Public Law 15-04 in 2006.
Mark your calendars for a special day of celebration on Commonwealth Covenant Day, which falls on the first Monday in October each year. This holiday has been observed since 1987 in honor of the unique relationship between the United States and the Commonwealth of Puerto Rico. The covenant, or agreement, between these two entities was established in 1952 and ensures that Puerto Ricans have equal rights as U.S. citizens while maintaining their distinct cultural identity. Let's take this opportunity to appreciate the rich history and heritage of Puerto Rico and its people, while also celebrating unity and diversity within our nation.
