About Commonwealth Covenant Day
Commonwealth Covenant Day falls on March 24 in the Commonwealth of the Northern Mariana Islands (CNMI). The CNMI Department of Commerce lists it as a holiday and the local U.S. District Court includes it on its 2026 schedule.
It commemorates the U.S. approval of the Covenant governing the islands’ political union with the United States. This is a CNMI-specific observance rather than a holiday throughout the United States.
Why Commonwealth Covenant Day matters
The Covenant is a political-status agreement emerging from negotiation and local self-determination. It should be understood in its Northern Mariana Islands historical and community context.
The holiday recalls federal approval on March 24, 1976; that approval is not the original 1975 agreement signing or the date the commonwealth’s institutions fully took shape.
History of Commonwealth Covenant Day
The Covenant was signed in February 1975, approved by the people of the Northern Mariana Islands in a June 1975 plebiscite, and approved by the U.S. Congress under Public Law 94-241 on March 24, 1976.
The annual March 24 public holiday is confirmed by CNMI official calendars. The exact initial enactment of the separate holiday schedule is not established from these reviewed records.

How to Observe Commonwealth Covenant Day
Explore the Covenant’s text and historical background from official civic and legal sources.
Respect diverse Chamorro and Carolinian perspectives and the community’s own discussion of political status.
Check CNMI-specific office, court, school and workplace schedules rather than assuming U.S. federal offices follow the same calendar.
Avoid simplifying the 1975 plebiscite, 1976 congressional action and later implementation into a single event.
