Guinea operates on Greenwich Mean Time (GMT), which is Coordinated Universal Time (UTC+0). The country does not observe daylight saving time, so the offset remains constant throughout the year.
All of Guinea follows the same timezone. Major cities including Conakry, Nzérékoré, Kankan, and Kindia all observe GMT. Conakry, the capital and largest city, is located on the Atlantic coast and serves as the country's main economic hub.
Guinea holds nearly half of the world's known bauxite reserves, the ore used to produce aluminum. The country is also the source of the Niger, Senegal, and Gambia rivers, earning it the nickname "the water tower of West Africa."
