Irkutsk Time in the context of "Samara Time"

There are 11 time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time (DST) has not been used in Russia since 26 October 2014. From 27 March 2011 to 26 October 2014, permanent DST was used.

UTC+08:00 is an identifier for a time offset from UTC of +08:00.

It is the most populous time zone in the world, as well as a possible candidate for ASEAN Common Time, mainly due to China's large population, with an estimated population of 1.4 billion people.

Kaliningrad Time (KALT; Russian: калининградское время, romanized: kaliningradskoye vremya) is the time zone two hours ahead of UTC (UTC+02:00) and one hour behind Moscow Time (MSK−1). It is used in Kaliningrad Oblast.

Until 2011, Kaliningrad Time was identical to Eastern European Time (UTC+02:00; UTC+03:00 with daylight saving time). On 27 March 2011, Russia moved to permanent DST, switching Kaliningrad time permanently to UTC+03:00. On 26 October 2014, this law was reversed but daylight saving time was not reintroduced, so Kaliningrad is now permanently set to UTC+02:00.

Moscow Time (MSK; Russian: моско́вское вре́мя, romanized: moskovskoye vremya) 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, after the non-continguous Kaliningrad enclave. 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.

Moscow Time is used to schedule trains (until 1 August 2018), ships, etc. throughout Russia, but air transport in Russia is scheduled using local time. Since 1 August 2018, Russian railways switched to using local time. Time in Russia is often announced throughout the country's other timezones on radio stations as Moscow Time, which is also registered in telegrams, etc. Descriptions of time zones in Russia are often based on Moscow Time rather than UTC; for example, Yakutsk (UTC+09:00) is said to be MSK+6 in Russia.

Yekaterinburg Time (YEKT) is the time zone five hours ahead of UTC (UTC+05:00) and 2 hours ahead of Moscow Time (MSK+2).

In 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC+05:00 in winter and UTC+06:00 in summer, Yekaterinburg time was set to UTC+06:00 until 2014, when it was reset back to UTC+05:00 year-round.

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). It is used in Omsk Oblast.

Krasnoyarsk Time (KRAT) is the time zone seven hours ahead of UTC (UTC+07:00) and 4 hours ahead of Moscow Time (MSK+4). KRAT is the official time zone for central and east Siberian regions of Krasnoyarsk Krai, Kemerovo Oblast, Khakassia and Tuva.

Novosibirsk Oblast used this time zone until 1993, when it was known as Novosibirsk Time (NOVT/NOVST). The Russian government renamed the time zone shortly after Novosibirsk opted for another time zone instead.

Yakutsk Time (YAKT) is a time zone in Russia which is nine hours ahead of GMT, and six hours ahead of Moscow Time (MSK). The time zone is also known as Asia/Yakutsk in the tz datbase.

The time zone covers Sakha Republic (western part), Amur Oblast and Zabaykalsky Krai.
