Seychelles in the context of Gulf Standard Time

Determining the boundaries between the continents is generally a matter of geographical convention and consensus. Several slightly different conventions are in use. The number of continents is most commonly considered seven (in English-speaking countries) but may range as low as four when Afro-Eurasia and the Americas are both considered as single continents. An island can be considered to be associated with a given continent by either lying on the continent's adjacent continental shelf (e.g. Singapore, the British Isles) or being a part of a microcontinent on the same principal tectonic plate (e.g. Madagascar and Seychelles). An island can also be entirely oceanic while still being associated with a continent by geology (e.g. Bermuda, the Australian Indian Ocean Territories) or by common geopolitical convention (e.g. Ascension Island, the South Sandwich Islands). Another example is the grouping into Oceania of the Pacific Islands with Australia and Zealandia.

There are three overland boundaries subject to definition:

The Common Market for Eastern and Southern Africa (COMESA) is a regional economic community in Africa with twenty-one member states stretching from Tunisia to Eswatini. COMESA was formed in December 1994, replacing a Preferential Trade Area which had existed since 1981. Nine of the member states formed a free trade area in 2000 (Djibouti, Egypt, Kenya, Madagascar, Malawi, Mauritius, Sudan, Zambia and Zimbabwe), with Rwanda and Burundi joining the FTA in 2004, the Comoros and Libya in 2006, Seychelles in 2009, Uganda in 2012 and Tunisia in 2018.

COMESA is one of the pillars of the African Economic Community.

The Comoros, officially the Union of the Comoros, is an archipelagic country made up of three islands in Southeastern Africa, located at the northern end of the Mozambique Channel in the Indian Ocean. Its capital and largest city is Moroni. The religion of the majority of the population, and the official state religion, is Islam. Comoros proclaimed its independence from France on 6 July 1975. The Comoros is the only country of the Arab League which is entirely in the Southern Hemisphere. It is a member state of the African Union, the Organisation internationale de la Francophonie, the Organisation of Islamic Co-operation, and the Indian Ocean Commission. The country has three official languages: Comorian, French and Arabic.

At 1,659 km (641 sq mi), the Comoros is the third-smallest African country by area after São Tomé and Príncipe and Seychelles. In 2019, its population was estimated to be 850,886. The sovereign state consists of three major islands and numerous smaller islands, all of the volcanic Comoro Islands with the exception of Mayotte. Mayotte voted against independence from France in a referendum in 1974, and continues to be administered by France as an overseas department. France has vetoed a United Nations Security Council resolution that would have affirmed Comorian sovereignty over the island. Mayotte became an overseas department and a region of France in 2011 following a referendum which was passed overwhelmingly.

São Tomé and Príncipe, officially the Democratic Republic of São Tomé and Príncipe, is an island country in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands of São Tomé and Príncipe, about 150 km (93.21 mi) apart and about 250 and 225 km (155 and 140 mi) off the northwestern coast of Gabon. With a population of 201,800 (2018 official estimate), São Tomé and Príncipe is the second-smallest and second-least populous African sovereign state after Seychelles.

The islands were uninhabited until Portuguese explorers João de Santarém and Pedro Escobar became the first Europeans to discover them in 1470. Gradually colonized and settled throughout the 16th century, they collectively served as a vital commercial and trade centre for the Atlantic slave trade. The rich volcanic soil and proximity to the equator made São Tomé and Príncipe ideal for sugar cultivation, followed later by cash crops such as coffee and cocoa. The lucrative plantation economy was heavily dependent upon enslaved Africans. Cycles of social unrest and economic instability throughout the 19th and 20th centuries culminated in peaceful independence in 1975 as a one-party communist state, which would remain in place until 1990. São Tomé and Príncipe has since remained one of Africa's most stable and democratic countries. São Tomé and Príncipe is a developing economy with a medium Human Development Index.

Greenwich Mean Time (GMT) is the local mean time at the Royal Observatory in Greenwich, London, counted from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a particular time unless a context is given. The term "GMT" is also used as one of the names for the time zone UTC+00:00 and, in UK law, is the basis for civil time in the United Kingdom.

Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the Sun crosses the Greenwich Meridian and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average (the arithmetic mean) moment of this event, which accounts for the word "mean" in "Greenwich Mean Time".

The Republic of Madagascar is a large island country in the Indian Ocean, off the coast of East Africa. Other Indian Ocean islands near Madagascar include the Mascarene Islands (split between the Republic of Mauritius and the French department of Réunion), the Republic of Seychelles, and the Comoro Islands (split between the Union of Comoros and the French department of Mayotte).

Southern Africa, or Southeastern Africa, is an African region that is intermediate between East Africa and Southern Africa. It comprises the countries Botswana, Eswatini, Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia and Zimbabwe in the mainland, with the island-nations of Madagascar, Mauritius, Comoros, and Seychelles also included.

Mauritius, officially the Republic of Mauritius, is an island country in the Indian Ocean, about 2,000 kilometres (1,100 nautical miles) off the southeastern coast of East Africa, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga, St. Brandon (Cargados Carajos shoals) and the Chagos Archipelagos. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where the population is concentrated, hosts the capital and largest city, Port Louis. The country spans 2,040 square kilometres (790 sq mi) and has an exclusive economic zone covering approximately 2,000,000 square kilometres (580,000 square nautical miles).

The 1502 Portuguese Cantino planisphere has led some historians to speculate that Arab sailors were the first to discover the uninhabited island around 975, naming it Dina Arobi. Called Ilha do Cirne or Ilha do Cerne on early Portuguese maps, the island was visited by Portuguese sailors in 1507. A Dutch fleet, under the command of Admiral Van Warwyck, landed at what is now the Grand Port District and took possession of the island in 1598, renaming it after Maurice, Prince of Orange. Short-lived Dutch attempts at permanent settlement took place over a century aimed at exploiting the local ebony forests, establishing sugar and arrack production using cane plant cuttings from Java together with over three hundred Malagasy slaves, all in vain. When French colonisation began in 1715, the island was renamed "Isle de France". In 1810, the United Kingdom seized the island and under the Treaty of Paris, France ceded Mauritius and its dependencies to the United Kingdom. The British colony of Mauritius now included Rodrigues, Agaléga, St. Brandon, the Chagos Archipelago, and, until 1906, the Seychelles. Mauritius and France dispute sovereignty over the island of Tromelin, the treaty failing to mention it specifically. Mauritius became the British Empire's main sugar-producing colony and remained a primarily sugar-dominated plantation-based colony until independence, in 1968. In 1992, the country abolished the monarchy, replacing it with the president.

Seychellois Creole (/seɪˈʃɛlwɑː/), also known as Kreol, Seselwa Creole French, and Seselwa Creole is the French-based creole language spoken by the Seychelles Creole people of the Seychelles. It is one of the national languages of the Seychelles.

Victoria is the capital and largest city of Seychelles, situated on the north-eastern side of Mahé, the archipelago's main island. The city was first established as the seat of the British colonial government. In 2010, the population of Greater Victoria (including the suburbs) was 26,450 (26.66%) out of the country's total population of 99,202.The port is known as Port Victoria.

João da Nova (Galician: Xoán de Novoa, Joam de Nôvoa; Spanish: Juan de Nova; Portuguese pronunciation: [ʒuˈɐ̃w dɐ ˈnɔvɐ]; c. 1460 in Maceda, Ourense, Galicia, Spain – July 16, 1509, in Kochi, India) was a Galician-born explorer in the service of Portugal. He is credited as the discoverer of Ascension and Saint Helena islands.

The Juan de Nova Island, in the Mozambique Channel, is named after him. The Farquhar atoll (in the Seychelles) was, for a long time, known as the João da Nova islands. It is sometimes thought that the Agaléga islands (in the Indian Ocean) were also named after him (although it is almost certain he never visited them).
