Daylight saving time

Prior to 2011, Russia moved its clocks backward and forward on the same annual cycle as Europe. On 27 March 2011, clocks were advanced as usual, but they did not go back on 30 October 2011, effectively making Moscow Time UTC+04:00 permanently. On 26 October 2014, following another change in the law, the clocks in most of the country were moved back one hour, but summer daylight saving time was not reintroduced; Moscow Time returned to UTC+03:00 permanently.

Soviet Union

After the Soviet Union was created, Moscow Time became UTC+02:00 and the various other time zones (up to UTC+12:00) were introduced throughout Russia and the rest of the

Soviet Union The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet ...

, for example Irkutsk Time UTC+07:00 (Irkutsk has since this always been MSK+5). Between 1917 and 1922 the time was less ordered, with daylight saving time some of those years, some with two hours addition, and some of those years with one or two hours extra winter time. On 21 June 1930, the Soviet Union advanced all clocks by one hour, effectively making the nation run on daylight saving time all year (the so-called decree time).

Decree time

In 1930, according to the decree of the Council of People's Commissars of the USSR Clocks across the country were moved forward by 1 hour from 21 June to 30 September, but the effect of this decree was then extended — later this time became known as decree time. The extension was due to a lack of electricity due to overloading of power plants in winter in the evening hours. In 1931, the Supreme Council of the National Economy proposed moving the clocks forward another hour, but the State Planning Committee opposed it. In 1935, a return to standard time was planned, which was never implemented.

Changes after 1937

After 1937 changes were made that eliminated the use of different times in relatively small areas. Thus, daylight saving time in some regions (in their western part) was changed by 1 hour forward, already 2 hours ahead of the standard time established in 1924, and in others (in the eastern part) - by 1 hour back, that is, the "daylight saving hour" was effectively abolished. From 1 December 1956, the official boundaries of time zones were to change, in particular to eliminate the presence of a number of regions in two time zones. As a result, daylight saving time in a number of places had to change either by 1 hour forward or by 1 hour back. The clocks were planned to be changed on 1 December 1956 at 00:00 Moscow time, but this happened on 1 March 1957, as reported in the central newspapers. The change of clocks in the regions was described in local newspapers. Thus, in the regional newspaper in the Molotov region it was noted that "today, on 1 March, in the Karagai, Ocher, Sivinsky, Vereshchaginsky regions of our region the working day began an hour earlier than before. (…) Now in our entire region the time differs from Moscow by two hours". After the 1957 reform, some regions in the European part of the

, located to the east of Moscow, officially remaining in the 3rd time zone, switched to Moscow time, thereby effectively abolishing the “decree hour” on all or part of their territory. By 1962, the time zone established in 1924 was 2 hours ahead of the standard time in some parts of the following regions: Altai Krai, Arkhangelsk, Vologda, Novosibirsk, Perm, Sakhalin (Sakhalin Island), Tomsk, Tyumen and Chita regions of the RSFSR, Ural region of the Kazakh SSR, as well as a number of other regions. By 1973, the "maternity leave hour" was abolished in the following regions (in all or part of the region's territory):Малый атлас СССР, М., ГУГК при СМ СССР, 1973 * Dagestan, Kabardino-Balkaria, Kalmykia, Komi, Mari, Mordovian, North Ossetian, Tatar, Chechen-Ingush, Chuvash, Yakut ASSR (Ust-Maisky and Tomponsky districts); Krasnodar, Stavropol, Krasnoyarsk, Khabarovsk territories; Amur, Arkhangelsk, Vladimir, Vologda, Voronezh, Gorky, Ivanovo, Irkutsk, Kostroma, Lipetsk, Magadan, Penza, Rostov, Ryazan, Tambov, Tyumen, Yaroslavl regions. * In 1977-1980, the Komi ASSR switched to Moscow time, which effectively meant the abolition of daylight saving time in the western part of the republic, including Syktyvkar, and the establishment of “zone time minus 1 hour” in the eastern part

Introduction of daylight saving time

From 1 April 1981, the country introduced regular switching of clocks to summer time. At the same time, it was necessary to restore the conformity of the applied time with the administrative time zones, in other words, to restore the “decree hour” that had been cancelled in various years in a number of regions. This was especially true for the regions of the 3rd time zone that switched to Moscow time, where, as of 1980, only Astrakhan, Volgograd, Izhevsk, Kirov, Kuibyshev (Samara), Saratov and Ulyanovsk retained their local time. On 1 April 1981, all regions moved their clocks forward by 1 hour, and on 1 October 1981, about 30 regions of the RSFSR did not move their clocks back, so that they could switch to summer time in the spring of 1982, relative to the restored decree time. However, due to the discontent of the population, these regions did not move their clocks to summer time in the spring of 1982, and in the fall they moved them back along with everyone else by 1 hour, returning to their usual winter time (without the "decree hour"). Thus, in those regions of the 3rd time zone, where Moscow time was used before 1981, MSK+1 time was in effect only from 1 October 1981 to 1 April 1982. The newspapers noted that the clarification of the boundaries of time zones and the new order of calculating time in them led to a disruption of the usual way of life of people, especially residents of the 3rd time zone, accustomed to Moscow time, and: "Especially in those areas where people watched live TV broadcasts from the capital. Now they sat in front of their TV sets an hour later than the local time count. Hence the many letters asking to restore the previous order.". After the introduction of seasonal clock changes, local time in the summer in many regions began to be ahead of the standard time established in 1924 by 2 hours, and in some by 3 hours. For example, the average solar noon in the west of Novosibirsk and Tomsk regions in the summer began to occur at 15:00, in the west of Altai Krai - at 14:48, in the west of Chita Oblast (Zabaikalsky Krai since 2008) - at 14:49.

Reforms of the time before the collapse of the USSR

In 1988, Volgograd and Saratov regions switched to the time of the neighboring western time zone, that is, they effectively abolished daylight saving time; in 1989, the Latvian, Lithuanian and Estonian SSRs, the Astrakhan, Kaliningrad, Kirov, Kuibyshev and Ulyanovsk regions, as well as the Ural region of the Kazakh SSR; in 1990, Georgia and Moldova. In addition, in 1990, some union republics abandoned seasonal clock changes. From 31 March 1991, decree time was officially abolished throughout the USSR., except for Turkmenistan and the western regions of Uzbekistan. At the same time, the seasonal change of clocks in 1991 was maintained in almost the entire territory of the USSR (except for the Tajik, Turkmen and Uzbek SSRs). Decree time was abolished without taking into account the fact that in many regions of the RSFSR it had already been abolished. Therefore, in these regions, local time from 29 September 1991 began to lag behind the standard time established in 1924 by 1 hour, and in the country as a whole, "winter" time almost everywhere shifted back by 1 hour. The abolition of decree time in the union republics in 1989-1991 coincided with the period of the collapse of the USSR. On 23 October 1991, the Council of the Republic of the Supreme Soviet of the RSFSR, by its resolution, obliged the government to restore daylight saving time on the territory of the RSFSR, stating that the implementation of the resolution of 4 February 1991 "on the abolition of daylight saving time and moving the clock back one hour on 29 September 1991 led to a reduction in the length of daylight hours on a significant part of the territory of the RSFSR, caused discontent among the population and led to an increase in electricity consumption.".
