Manu'a Cession Day is observed in American Samoa every July 16 to commemorate the cession of the Manu'a islands to the United States. This governmental holiday marks the signing of the Deed of Cession of Manu'a in 1904 between the United States and Tui Manuʻa Elisala, the last Tuimanuʻa chief, which integrated the Manu'a islands into American Samoa. The day is characterized by the closure of local governmental offices, while federal offices and the private sector remain open. Celebrations typically include a special church service and concerts featuring traditional songs and dances organized by youth groups. This holiday reflects the historical significance of the region and its cultural heritage.
