Cape Verde Time

Cape Verde Time (CVT) is a time zone used by the Atlantic island nation of Cape Verde. The zone is one hour behind UTC (UTC−01:00).

Time zones of Africa:

Light Blue	Cape Verde Time[a] (UTC−1)
Blue	Greenwich Mean Time (UTC)
Red	Central European Time West Africa Time (UTC+1)
Ochre	Central Africa Time Eastern European Time Egypt Standard Time South African Standard Time (UTC+2)
Green	East Africa Time (UTC+3)
Turquoise	Mauritius Time[b] Seychelles Time[b] (UTC+4)

^a The islands of Cape Verde and Canary Islands are to the west of the African mainland.
^b Mauritius and the Seychelles are to the east and north-east of Madagascar respectively.

This time zone applies all the year round. Due to its geographical location, completely west of the meridian 22°30'W (which forms the boundary between UTC−01:00 and UTC−02:00) Cape Verde effectively observes permanent daylight saving, given that the position of the archipelago is totally within the boundaries of UTC−02:00, the time zone observed until 1975.
