Gospel Day, also known as Missionary Day, is observed in French Polynesia every March 5. This public holiday honors the missionaries who introduced Christianity to the region, with particular significance in French Polynesia as Tubuai was the first island where the gospels were taught in the native language. The arrival of the first missionaries in the early 1820s marked the beginning of Christianity's influence, which is now the predominant religion in the area, primarily represented by various Protestant denominations, particularly the Maóhi Protestant Church, along with a significant Roman Catholic community. On Gospel Day, special services are held in churches of all denominations, making it an important occasion for believers across the islands. This holiday is celebrated throughout Oceania, although each country observes it on different dates.
