Tokehega Day is observed in Tokelau every September 3, commemorating the anniversary of the Treaty of Tokehega, which was signed on December 2, 1980, to establish the maritime boundary between American Samoa and Tokelau. The treaty, which came into force on September 3, 1983, resulted in Swains Island, known as Olohega in Tokelau, becoming part of American Samoa, a change that many Tokelauan citizens wish to reverse. The name "Tokehega" is derived from "Toke," representing Tokelau, and "hega," from Olohega. This public holiday serves as a reminder of the historical ties and cultural significance of the islands involved. Celebrations typically include reflections on the treaty's impact and discussions about the future of Swains Island.
