Yakutsk Time (YAKT) is a time zone in Russia which is nine hours ahead of UTC, and six hours ahead of Moscow Time (MSK).
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
Russia, officially the Russian Federation, is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres (6,612,100 sq mi), Russia is the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with about 146.77 million people as of 2019, excluding Crimea. About 77% of the population live in the western, European part of the country. Russia's capital, Moscow, is the largest metropolitan area in Europe proper and one of the largest cities in the world; other major cities include Saint Petersburg, Novosibirsk, Yekaterinburg and Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Finland, Estonia, Latvia, Lithuania and Poland, Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia and North Korea. It shares maritime borders with Japan by the Sea of Okhotsk and the U.S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia, both of which are internationally recognized as parts of Georgia.
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 permanently on 26 October 2014; before that date it had been set to UTC+04:00 year-round since 27 March 2011.
The time zone covers Sakha Republic (western part), Amur Oblast and Zabaykalsky Krai.
The Republic of Sakha (Yakutia) (Russian: Республика Саха, tr.Respublika Sakha , IPA: [rʲɪsˈpublʲɪkə sɐˈxa jɪˈkutʲɪjə]; Yakut: Саха Өрөспүүбүлүкэтэ, translit. Sakha Öröspüübülükete, IPA: [saˈxa øɾøsˈpyːbylykete] is a federal Russian republic. It had a population of 958,528 at the 2010 Census, mainly ethnic Yakuts and Russians.
Amur Oblast is a federal subject of Russia, located on the banks of the Amur and Zeya Rivers in the Russian Far East. The administrative center of the oblast, the city of Blagoveshchensk, is one of the oldest settlements in the Russian Far East, founded in 1856. It is a traditional center of trade and gold mining. The territory is accessed by two railways: the Trans-Siberian Railway and the Baikal–Amur Mainline. As of the 2010 Census, the oblast's population was 830,103.
Zabaykalsky Krai is a federal subject of Russia that was created on March 1, 2008 as a result of a merger of Chita Oblast and Agin-Buryat Autonomous Okrug, after a referendum held on the issue on March 11, 2007. Formerly part of the Siberian Federal District, the Krai is now part of the Russian Far East as of November 2018 in accordance with a decree issued by Russian President Vladimir Putin. The administrative center of the krai is located in the city of Chita. As of the 2010 Census, the population was 1,107,107.
On 27 March 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC+9 in winter and UTC+10 in summer, Yakutsk Time became fixed at UTC+10 until 2014, when it was reset back to UTC+9 year-round.
Daylight saving time (DST), also daylight savings time or daylight time, also summer time, is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn to standard time. In effect, DST causes a lost hour of sleep in the spring and an extra hour of sleep in the fall.
Japan Standard Time or JST is the standard timezone in Japan, 9 hours ahead of UTC. There is no daylight saving time, though its introduction has been debated several times. During World War II, it was often called Tokyo Standard Time.
The Eastern Time Zone (ET) is a time zone encompassing part or all of 22 states in the eastern part of the contiguous United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama in Central America, and the Caribbean Islands.
European Summer Time 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, in order to make the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time to be found in many other parts of the world.
Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer.
The Yukon Time Zone was a time zone that kept standard time; Yukon Standard Time (YST) was obtained by subtracting nine hours from Coordinated Universal Time (UTC) resulting in UTC−09:00. Yukon Daylight Time (YDT) when observed was eight hours behind UTC. In 1983 the UTC−09:00 based time zone was restructured and renamed the Alaska Time Zone.
UTC+03:00 is an identifier for a time offset from UTC of +03. 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.
South African Standard Time (SAST) is the time zone used by all of South Africa, Botswana as well as Eswatini and Lesotho. The zone is two hours ahead of UTC (UTC+02:00) and is the same as Central Africa Time. Daylight saving time is not observed in either time zone. Solar noon in this time zone occurs at 30° E in SAST, effectively making Pietermaritzburg at the correct solar noon point, with Johannesburg and Pretoria slightly west at 28° E and Durban slightly east at 31° E. Thus, most of South Africa's population experience true solar noon at approximately 12:00 daily.
Omsk Time (OMST) is a time zone in Russia that is six hours ahead of UTC (UTC+06:00), and 3 hours ahead of Moscow Time (MSK).
There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time is not used in Russia.
Canada is divided into six time zones, based on proposals by Scottish Canadian railway engineer Sir Sandford Fleming, who pioneered the use of the 24-hour clock, the world's time zone system, and a standard prime meridian. Most of Canada operates on standard time from the first Sunday in November to the second Sunday in March and daylight saving time the rest of the year.
Further-eastern European Time (FET) is a time zone defined as three hours ahead of UTC (UTC+03:00) without daylight saving time, the zone immediately higher than the Eastern European Time. As of September 2016, it is used in Belarus, western Russia and Turkey, and is also called Minsk Time, Moscow Time (MSK), or Turkey Time (TRT).
The UTC offset is the difference in hours and minutes from Coordinated Universal Time (UTC) for a particular place and date. It is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh]. So if the time being described is one hour ahead of UTC, the UTC offset would be "+01:00", "+0100", or simply "+01".
Yekaterinburg Time (YEKT) is the time zone five hours ahead of UTC (UTC+05:00) and 2 hours ahead of Moscow Time (MSK+2).
East Africa Time, or EAT, is a time zone used in eastern Africa. The time zone is three hours ahead of UTC (UTC+03:00), which is the same as Arabia Standard Time, Further-eastern European Time, Moscow Time and Eastern European Summer Time.
Irkutsk Time (IRKT) is the time zone eight hours ahead of UTC (UTC+08:00) and 5 hours ahead of Moscow Time (MSK+5).
Vladivostok Time (VLAT), is a time zone in Russia, named after the city of Vladivostok. It is ten hours ahead of UTC (UTC+10:00) and seven hours ahead of Moscow Time (MSK+7).
Kamchatka Time (PETT), also known as Anadyr Time (ANAT), is a time zone in Russia, named after the Kamchatka Peninsula. It is 12 hours ahead of UTC (UTC+12:00) and 9 hours ahead of Moscow Time (MSK+9). This time zone is used in the two easternmost regions of Russia after October 2014 and was also used before the time zone reform of 2010.
Kaliningrad Time is the time zone two hours ahead of UTC (UTC+02:00) and 1 hour behind Moscow Time (MSK−1). It is used in Kaliningrad Oblast.
