Guam History and Chamorro Heritage Day is observed on the first Monday in March, specifically on March 2 in 2026. This national public holiday celebrates the indigenous Chamorro people and their culture, which has been significantly impacted by centuries of colonialism. The day features traditional songs, dances, food, and storytelling, aiming to reclaim lost narratives and foster a vision for the future of the Chamorro identity. It also marks the beginning of 'Mes Chamoru,' a month filled with cultural events, including a re-enactment of Ferdinand Magellan's arrival in Guam, intended to remind Guamanians of their history rather than to celebrate it. The holiday embodies core Chamorro values such as respect, community, reciprocity, and love, providing an opportunity for Guamanians to honor their heritage and assert their right to self-determination.
