Within 24 hours of the Earth makes a full rotation.Therefore, in different parts of the globe clocks show different time.For ease of reference the entire territory of the Earth divided into time zones.Their boundaries were determined by the meridians and apart from each other by 15 degrees.But this division is inconvenient for many states.Therefore, small countries feel the local time of the capital.A large number of countries had to allocate time zones.But all the same basic calculations, such as time, rail and flight, conducted by Moscow time.In Russia, this is a landmark Moscow.All times are other cities is measured from it.
history timezones
until the 19th century was no question the time of confusion.Each state has lived in their local time and travel a great distance were a rarity.But with the advent of rail traffic problem in the scheduling of trains.Therefore, at the International Congress in the 80s of the 19th century it was decided to divide the territory of the Earth in the time zone.The countdown began to lead the prime meridian - Greenwich - east.The difference between them is one hour.Therefore, just turned 24 belt.But until recently, have not yet resolved all the issues associated with it, and a lot of confusion in the timing.
How is the division into time zones
theory, time zones are on the meridians and are spaced apart from each other by 15 degrees.But in practice they are often displaced, it happens that they even disappear.This is due to the division of the state territory.And many countries, regardless of the zones, introduced at the metropolitan time.Therefore, the division into zones is now often conditional.But in the States, occupying a large area, it is important to not only the local time but also the metropolitan.For example, Russia is counting on Moscow.All times are Greenwich it from the second.But Russian cities do not count the time from him, and from Moscow.
Introduction lap time in Russia
only in 1919 in Russia was introduced by the international system of time zones.The country is divided into 11 zones.But not always their border runs along the meridians.For example, a reference point in Russia considered Moscow.All times it was passed from Greenwich UTC + 2.UTC - is a worldwide symbol of the world Greenwich Mean Time.But since the city is located on the border zone, then we enter the summer time, and the difference became UTC + 3, which is more in line with natural rhythms.
What time zone in Moscow today
Several times in the history of the country is a change in the division into time zones.In the 30 years it was abolished daylight saving time, and Moscow remained belt UTC + 3.It was believed that this was the most appropriate division, because in many countries, if the city lies on the border zone, it belongs to the East.But from 1981 to 2011 in Russia again entered the summer.Moscow became the summer ahead of Greenwich for 4 hours.After the cancellation of the annual transfer of the shooter and the capital remained in the time zone UTC + 4.And now we live 2 hours ahead to the time taken by dividing the country's time zone.
time zones in Russia is
In 2010, the country was changed to the division into zones.Now Russia is located in the 9 time zones.Completely disappeared Srednevolzhskiy Kamchatka and Chukotka-belt.Udmurtia and Samara moved to Moscow time, and Chukotka and Kamchatka - to Magadan.The difference between zones is one hour.To calculate the local time, you need to know what time zone you're in.How time zones are considered with respect to Moscow?
count them coming from Kaliningrad.This is the first time zone.The difference with Moscow time is 1 hour.After all, this city is located west of Moscow.All European Russia lives by the time of the capital.It differs from Greenwich 4 hours.In our country, this is the second time zone.It is the most populous.The next zone - the third, but the difference with Moscow is not 1 and 2:00.It includes Orenburg, Sverdlovsk, Tyumen and Chelyabinsk region, Perm, Khanty-Mansiysk District, Republic of Bashkortostan and some other administrative units.
remaining time zones differ by one hour.Not always the boundaries associated with the international division into time zones.For example, the fourth zone is accepted only in the Altai and in several neighboring regions, and the fifth - in Tuva, Khakassia and Krasnoyarsk Krai.
The most common zoning depends on the borders of the republics and regions, but there are exceptions.For example, Yakutia lies in the three zones, and the Sakhalin region - in two.The most distant regions of Russia differ in time with Moscow is 8 hours.Time in them is calculated by the formula from the Moscow time zone - MSK + 8.The "plus" indicates that the zone is located east and the negative - to the west of Moscow.
Because of the constant transfer time and confusion with time zones Moscow time a little bit does not coincide with astronomical.But still count him in the country conducted by Moscow.All times it is necessary to know that when you move to another region to correctly set the clock.
