Time in Botswana is given by a single time zone, officially denoted as Central Africa Time (CAT; ). Botswana has never observed daylight saving time. Botswana, as the Bechuanaland Protectorate, has observed CAT since 1903. In 1885 it used the South African Standard Time (SAST; ) as British Bechuanaland. Before adopting SAST and CAT, it observed local mean time (LMT; UTC+01:43).
Daylight saving time in Botswana was adopted in 1943 and consequently disposed of in 1944.
