Guam History and Chamorro Heritage Day2026 · Date · History · Messages
Guam law designates the first Monday in March as Guam History and Chamorro Heritage Day, and the federal District Court of Guam’s 2026 holiday calendar lists 2 March 2026.
About Guam History and Chamorro Heritage Day
Guam History and Chamorro Heritage Day is a Government of Guam legal holiday observed on the first Monday in March. Public Law 32-145 added that title and placement to Guam’s public-holiday law in 2014.
The holiday provides a civic occasion to learn about Guam’s history and CHamoru heritage. The legal title uses the spelling “Chamorro,” while many contemporary institutions and community members use “CHamoru” when referring to the Indigenous people, language and culture.
Why Guam History and Chamorro Heritage Day matters
The day highlights Guam’s history and Indigenous CHamoru heritage within a territorial public-holiday framework.
Historical learning should not imply that Guam’s history began with European contact. Respectful observance can include Indigenous history, language, cultural knowledge and the island’s later political and social history using Guam-based sources.
History of Guam History and Chamorro Heritage Day
Government of Guam material records an observance under the current title on March 3, 2014 at the request of Senator Tommy Morrison.
Bill No. 286-32, introduced by Senator Tommy Morrison with co-sponsors, was enacted as Public Law 32-145 on April 28, 2014 and established Guam History and Chamorro Heritage Day as a legal holiday on the first Monday in March.
A separate legacy provision in the Guam Code still contains the older Guam Discovery Day wording for the first Monday in March, and the compiler note states that Public Law 32-145 did not address that provision. The two provisions should therefore not be collapsed into a claim of express repeal.
