Namibia since September 2017 is in the Central Africa Time zone at UTC+02:00, congruous with South African Standard Time.
The country kept the time regulations of South Africa when it gained independence in 1990. Triggered by fears for children walking to school before sunrise, in 1993 the Namibian Time Bill was passed, stipulating the switch to Winter time as one of only a few countries in the world. Only the Zambezi Region in the far north-east remained at UTC+02:00. In the 2010s criticism of Namibian time regulations arose, mainly due to incompatibilities with South Africa, Namibia's main trading partner, and the hassle of different time regulations in the Caprivi Strip.
After public consultations the Namibian Time Bill 2017 was tabled in the National Assembly in February 2017 and passed by National Council in August.
Upon Namibian independence the country used a single time zone, keeping time regulation as previously prescribed by the occupying nation, South Africa. Triggered by fears for school children walking to school before sunrise, discussions in the National Assembly started in 1992, [1] and on 10 November 1993 the Namibian Time Bill (#39 of 1993) was proposed. This bill defined the Namibian Standard Time. [2]
From 1994 until 2017 Namibia used Winter time, the practice of setting clocks back during winter months by one hour. In this period Namibian Standard Time was at UTC+02:00 (derived from South African Standard Time and equivalent to Central Africa Time) in summer, and UTC+01:00 (equivalent to West Africa Time) in winter. [3] Winter time began on the first Sunday in April at 03:00, and lasted until the first Sunday in September, 02:00 hours. In the Zambezi Region in the far north-east of Namibia clocks were not changed and remained on Central Africa Time all year round so that during winter time, Namibia spanned two time zones. [1]
Namibia was one of only a few countries in the world to implement winter time instead of daylight saving time. Ireland still adjusts clocks in Winter since 1971 [4] [5] while Czechoslovakia used the practice only in 1946 and never repeated it. [6] In a regular daylight saving time scheme, the "normal" time is observed in the winter, and clocks are turned forward during the summer. In winter time, normal time is observed in the summer, and clocks are turned back by one hour in the winter. In timekeeping, then, it is equivalent to daylight saving time, differing only in which season is considered the regular time. However, the purpose was not to utilise additional hours of daylight in the evening, but to prevent children from walking to school in darkness in the morning, to decrease the risk of injuries and assaults. [1]
If expressed as summer times, these would have been equivalent to West Africa Summer Time and West Africa Standard Time, however Namibia was the only state in Africa to use the combination of UTC+01:00 and UTC+02:00. Central European Time also uses UTC+01:00 and UTC+02:00, but the northern seasons are opposite to the southern hemisphere.
In the 2010s repeated calls from businesses and private individuals were made to abolish winter time, citing incompatibilities with South Africa, Namibia's main trading partner, as well as a "loss of productivity". [1]
This resulted in an official investigation by the Ministry of Home Affairs and Immigration. During the polls, 97% of the 3,507 questioned people were in favour of the +2 difference to Greenwich Mean Time, and about 88% wanted to abolish winter time. After the Cabinet was likewise against changing clocks in autumn and spring, minister Pendukeni Iivula-Ithana proposed a new bill to that effect in February 2017. [7] The Home Affairs ministry stated that winter time would proceed in 2017, as discussions were still ongoing. [8]
The National Council passed the Namibian Time Bill 2017 in August 2017 and repealed the 1993 act, abolishing daylight saving time in the country and setting Central Africa Time as the year-round time zone nationwide. [9]
Daylight saving time (DST), also referred to as daylight saving(s), daylight savings time, daylight time (United States and Canada), or summer time (United Kingdom, European Union, and others), is the practice of advancing clocks to make better use of the longer daylight available during summer so that darkness falls at a later clock time. The typical implementation of DST is to set clocks forward by one hour in spring or late winter, and to set clocks back by one hour to standard time in the autumn (or fall in North American English, hence the mnemonic: "spring forward and fall back").
Japan Standard Time, or Japan Central Standard Time, is the standard time zone in Japan, 9 hours ahead of UTC (UTC+09:00). Japan does not observe daylight saving time, though its introduction has been debated on several occasions. During World War II, the time zone was often referred to as Tokyo Standard Time.
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, and the state of Quintana Roo in Mexico.
The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC) when standard time (UTC−07:00) is in effect, and by subtracting six hours during daylight saving time (UTC−06:00). The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the exact specification for the location of time zones and the dividing lines between zones is set forth in the Code of Federal Regulations at 49 CFR 71.
Central European Time (CET) is a standard time of Central, and parts of Western Europe, which is one hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Budapest Time, Madrid Time, Paris Time, Rome Time, Prague time, Warsaw Time or Romance Standard Time (RST).
Summer time in Europe is the variation of standard clock time that is applied in most European countries in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, with a view to making the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time (DST) to be found in some other parts of the world.
Central European Summer Time, sometimes referred to as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Eastern European Time, Central Africa Time, South African Standard Time, Egypt Standard Time and Kaliningrad Time in Russia.
Time in New Zealand is divided by law into two standard time zones. The main islands use New Zealand Standard Time (NZST), 12 hours in advance of Coordinated Universal Time (UTC) / military M (Mike), while the outlying Chatham Islands use Chatham Standard Time (CHAST), 12 hours 45 minutes in advance of UTC / military M^ (Mike-Three).
Moscow Time is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg. It is the second-westernmost of the eleven time zones of Russia. It has been set to UTC+03:00 without DST since 26 October 2014; before that date it had been set to UTC+04:00 year-round on 27 March 2011.
UTC+03:00 is an identifier for a time offset from UTC of +03:00. In areas using this time offset, the time is three hours later than the Coordinated Universal Time (UTC). Following the ISO 8601 standard, a time with this offset would be written as, for example, 2019-02-08T23:36:06+03:00.
Israel Standard Time (IST) is the standard time zone in Israel. It is two hours ahead of UTC (UTC+02:00).
Australia uses three main time zones: Australian Eastern Standard Time, Australian Central Standard Time and Australian Western Standard Time.
Egypt Standard Time (EGY) is UTC+02:00, which is equivalent to Eastern European Time, Central Africa Time, South African Standard Time and Central European Summer Time, and is co-linear with neighbouring Libya and Sudan. Egypt has used Eastern European Summer Time (UTC+03:00), during the summer periods from 1957 to 2010, 2014, 2015, and 2023.
Central Africa Time or CAT, is a time zone used in central and southern Africa. Central Africa Time is two hours ahead of Coordinated Universal Time (UTC+02:00), which is the same as the adjacent South Africa Standard Time, Egypt Standard Time, Eastern European Time, Kaliningrad Time and Central European Summer Time.
Daylight saving time in the Americas is the arrangement in the Americas by which clocks are advanced by one hour in spring and moved back in autumn, to make the most of seasonal daylight. The practice is widespread in North America, with most of Canada and the United States participating, but much less so in Central and South America.
African countries, apart from Egypt, do not use daylight saving time (DST) although some did in the past. Only the territories of the Canary Islands, Ceuta and Melilla (Spain) and Madeira (Portugal) implement DST from the last Sunday in March to the last Sunday in October. Although these regions politically belong to Europe, they are geographically part of Africa. They have DST schedules according to European Union rules.
Daylight saving time (DST), also known as summer time, is the practice of advancing clocks during part of the year, typically by one hour around spring and summer, so that daylight ends at a later time of the day. As of 2024, DST is observed in most of Europe, most of North America and parts of Africa and Asia around the Northern Hemisphere summer, and in parts of South America and Oceania around the Southern Hemisphere summer. It was also formerly observed in other areas.
Winter time is the practice of shifting the clock behind the standard time during winter months, usually −1 hour. It is a form of daylight saving time in which standard time is in effect during summer months, rather than the usual case where standard time is in effect during winter months. However, while summer time is widely applied, use of winter time has been and is very rare.
Time in the Kingdom of the Netherlands is denoted by Central European Time during the winter as standard time in the Netherlands, which is one hour ahead of coordinated universal time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of coordinated universal time (UTC+02:00). The Caribbean Netherlands – which consist of the islands of Bonaire, Sint Eustatius and Saba – all observe Atlantic Standard Time (AST) year-round, which is four hours behind coordinated universal time (UTC−04:00).
Time in Poland is given by Central European Time. Daylight saving time, which moves an hour ahead, is observed from the last Sunday in March to the last Sunday in October. This is shared with several other EU member states.
To byla jediná doba, kdy byl u nás zaveden zimní čas, je to nejspíš i světový unikát, poté se měnil už pouze v ten letní.
