Ghana, as the erstwhile
British Gold Coast colony, adopted Greenwich Mean Time (UTC±00:00) on 2 November 1915 via the Interpretation Amendment Ordinance.[5] Daylight saving time (DST) was first introduced in 1919, advancing the clock twenty minutes to
UTC+00:20 at 02:00 (local time) on the first day of September and reverting to UTC±00:00 – the
standard time – on the first day of January at 02:00.[6] In 1940, the start date was changed to 1 May.[7] DST was briefly abolished with
UTC+00:30 adopted as standard time between 1942 and 1945,[8] before both changes were revoked and UTC±00:00 was readopted as standard time.[9] DST was abolished the same year, however, but briefly reintroduced again for the final time between 1950 and 1956 with a thirty-minute offset from UTC.[10]
