How many time zones does Russia have?

There are eleven time zones in Russia (within its internationally recognized borders), 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.

Daylight saving time in Russia was originally introduced on 1 July [14 July, N.S.] 1917 by a decree of the Russian Provisional Government. However, it was abandoned by a decree of the Soviet government six months later.

Daylight saving time was re-introduced in the USSR in 1981, beginning on 1 April and ending on 1 October each year, until mid-1984, when the USSR began following European daylight saving time rules, moving clocks forward one hour at 02:00 local standard time on the last Sunday in March, and back one hour at 03:00 local daylight time on the last Sunday in September until 1995, after which the change back occurred on the last Sunday in October.

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 Time was not reintroduced; Moscow Time returned to UTC+03:00 permanently.
