Samara Time

Samara Time (SAMT) is the time zone four hours ahead of UTC (UTC+4) and 1 hour ahead of Moscow Time (MSK+1). Samara Time is used in Astrakhan Oblast, Samara Oblast, Saratov Oblast, Udmurtia, and Ulyanovsk Oblast.

History
Until a reform on 28 March 2010, Samara Time was UTC+4 in winter and Samara Summer Time (SAMST) was UTC+5 in summer. From that date, Samara Time was abolished with the two regions effectively joining Moscow Summer Time. In March 2011, Moscow time was moved forward to UTC+04:00 year-round, and Samara Time was reinstated on 26 October 2014, when Moscow time moved back one hour to UTC+03:00 year-round and Samara Oblast and Udmurtia remained on UTC+04:00. On 27 March 2016, Ulyanovsk Oblast and Astrakhan Oblast switched to Samara Time by moving the clock 1 hour forwards from Moscow time. On 4 December 2016, Saratov Oblast also switched to Samara Time by moving forward 1 hour from Moscow time. On 28 October 2018, Volgograd Oblast also switched to Samara Time by moving forward 1 hour from Moscow time, but this change was reverted on 27 December 2020.
