Time zone
Chad observes a single time zone, West Africa Time (WAT; UTC+01:00). The country does not observe daylight‑saving time.
Geographical context
Located in north‑central Africa, Chad lies longitudinally between approximately 14°E and 24°E, placing it within the UTC+01:00 offset zone.
Historical adoption
The use of UTC+01:00 in Chad dates back to the mid‑20th century, when the French colonial administration standardized time across its West African territories. After independence in 1960, Chad retained West Africa Time. No legislative changes have introduced daylight‑saving time or altered the offset since then.
Legal and administrative references
Chad’s official time is defined in national regulations concerning civil timekeeping and is reflected in government documents, legal notices, and international standards (e.g., the IANA time zone database entry “Africa/Ndjamena”).
International coordination
In international contexts—such as aviation, telecommunications, and the United Nations—Chad is identified with the UTC+01:00 offset. The country’s capital, N'Djamena, and all other regions follow the same time.
