Guinea-Bissau 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-Bissau follows the same timezone. Major cities including Bissau, Bafatá, and Gabú all observe GMT. Bissau, the capital and largest city, is located on the Geba River estuary on the Atlantic Ocean.
Guinea-Bissau is home to the Bijagós Archipelago, a UNESCO Biosphere Reserve consisting of 88 islands. The country is one of the world's largest cashew nut producers, with cashews accounting for about 90% of its exports.
