This is a list of public holidays in Saint Helena, Ascension and Tristan da Cunha, a British overseas territory in the South Atlantic Ocean consisting of Saint Helena, Ascension Island and Tristan da Cunha.
Ascension Island was discovered on Ascension Day in 1503; it is celebrated on that island and also in Tristan da Cunha.
In the archipelago of Tristan da Cunha, Anniversary Day celebrates the day on which the islands were formally annexed to the British Empire in 1816.
Ratting Day is a local observance on Tristan da Cunha island and its date is declared annually by the Chief Islander; it can be moved at short notice depending on weather conditions.
[2] The territory has a largely Christian population and two further dates are therefore locally notable in the calendar: Easter Sunday and Whit Sunday (the Pentecost), both of which (along with their associated public holidays of Good Friday, Easter Monday, Ascension Day and Whit Monday) vary each year.
