Gospel Day is observed in the Republic of the Marshall Islands every first Friday of December. This public holiday commemorates the arrival of the first missionaries, specifically American Congregationalists, who landed at Jailut Atoll in 1857, bringing Christianity to the isolated archipelago. The United Church of Christ, a Protestant denomination, is now the largest religious group in the country, representing about 55% of the population. Celebrations on Gospel Day resemble Thanksgiving in North America, with family gatherings and celebratory meals being central to the festivities. Additionally, the Marshallese people attend special church services to honor the missionaries. Other religious groups present in the Marshall Islands include the Assemblies of God, Roman Catholics, and members of the Baha'i Faith, among others.
