Africa, the world's second-largest and second-most populous continent, spans across six different time zone offsets from Coordinated Universal Time (UTC): UTC−01:00 to UTC+04:00. [2] [3] As Africa straddles the equator and tropics, there is little change in daylight hours throughout the year [4] and as such daylight saving time is currently observed in only one country, Morocco, however it was also previously observed in several other countries. [5] [6]
Before the wide adoption of standard time zones, local mean time was widely used in railway time for train timetables and telegraphic time for telegraphy. [7] Local mean time is a solar time that corrects the variations of local apparent time by forming a uniform time scale at a specific longitude; [8] for instance, Liberia observed UTC-0:44:30 instead of an approximate offset such as UTC-01:00. [9] British Rhodesia (at the time administered by the private British South Africa Company) was the first area in Africa to adopt standard time, switching to UTC+02:30 on 1 August 1899 as the previous time standards proved problematic for the railway system. [10] Other countries followed suit, and by 1912, most Portuguese, [11] French and British territories had adopted a standard offset. [12] Liberia was the last country in Africa to adopt a standard offset, doing so on 7 January 1972. [13]
Names for the offsets vary by country and jurisdiction: [3] in Africa, UTC+01:00 is commonly known as "West Africa Time", however Algeria, [14] Morocco and Tunisia [15] designate the offset by its European name, "Central European Time"; UTC+02:00 – commonly known as "Central Africa Time" – is designated as "South African Standard Time" by Eswatini, Lesotho and South Africa, [16] whilst Egypt [17] and Libya [18] designate it by its European name "Eastern European Time". Cape Verde is the only country in Africa which observes UTC-01:00, where it is known as Cape Verde Time (CVT); thirteen countries observe UTC±00:00, fourteen [lower-alpha 1] observe UTC+01:00, sixteen [lower-alpha 1] observe UTC+02:00, nine observe UTC+03:00, and two (Mauritius and Seychelles) observe UTC+04:00, where the offset is designated as Mauritius Time (MUT) [19] and Seychelles Time (SCT) [20] respectively. [3]
Before the wide adoption of standard time zones, local mean time, which is a solar time that corrects the variations of local apparent time by forming a uniform time scale at a specific longitude, [8] such as railway time for train timetables and telegraphic time for telegraphy, was widely used. [7] Due to the large size of the British company rule in Rhodesia, it meant Rhodesia observed three standards of time: UTC+01:30, +2:15 and +2:30; this was problematic for the railway system, so on 1 August 1899 the standard time zones UTC+02:30 was adopted nationwide, [10] consequently resulting in this being the first standard time in Africa. This would soon be followed by Egypt, which adopted standard time on 1 October 1900; [21] [22] Nigeria adopted standard time on 1 July 1905, [23] Seychelles in 1906, [24] Mauritius on 1 January 1907, [21] Togo in 1907, [12] Algeria on 11 March 1911 [9] and Tunisia on 12 April 1911. [21] Most Portuguese territories (including Cape Verde and Mozambique) adopted standard time on 26 May 1911, [11] followed by most remaining French and British territories on 1 July 1911 and 1 January 1912. [21] [25] The Gambia adopted standard time in 1918. [26] Liberia was the last country in Africa to adopt a standard offset, doing so on 7 January 1972. [13] The latest time change was South Sudan, which switched from UTC+3 to +2 on 1 February 2021. [27]
As Africa straddles the equator and tropics, there is little change in daylight hours throughout the year [4] and as such daylight saving time (DST) is currently observed in only one country, Morocco, however it was also previously observed in several other countries: the countries that formerly observed DST are South Africa, which last observed it in 1944, [28] Cape Verde in 1945, [29] Madagascar in 1954, [29] Ghana in 1956, [30] Sierra Leone in 1962, [31] Algeria and Chad in 1980, [9] Sudan in 1985, [9] Tunisia in 2008, [32] Mauritius in 2009, [29] Libya in 2012, [33] [34] Egypt in 2015, [35] and Namibia in 2017. [36] Since 2019, [37] Morocco has observed UTC+01:00 year round except during the month of Ramadan, when it switches to UTC±00:00 as to not interfere with the month's fasting ( sawm ). [38] [39]
