Abidjan is in Cote d'Ivoire and is currently on UTC+0. Its time zone is Africa/Abidjan.
Abidjan does not observe daylight saving time. It stays on UTC+0 all year, so the difference to any other place that also holds a fixed offset never changes.
The weekend in Abidjan falls on Saturday and Sunday. A working day of 9:00 AM to 6:00 PM is the assumption used on the board.
