Time in Ukraine is defined as UTC+02:00 and in summer as UTC+03:00. Part of Eastern European Time, it is locally referred to as Kyiv Time (). The change for the summer time takes place in the last Sunday of March at 03:00 when the time is changed by an hour ahead, and the last Sunday of October at 04:00, when the time changes an hour back. In this way, the clocks in Ukraine are always one hour ahead of those in central Europe. Geographical description The territory of Ukraine in Europe stretches 17°57' along a longitude or about 1.2 hours. Almost 95% of its territory is located in the Eastern European Time Zone with exceptions of its western and eastern extremities. Small portion of Zakarpattia Oblast is located in the Central European Time Zone, while Luhansk Oblast, most of Donetsk Oblast, and part of Kharkiv Oblast are geographically located in the Further-eastern European Time Zone. However, the whole country officially observes Eastern European Time.

History Daylight saving time in Ukraine was introduced in the early 1980s. On 20 September 2011, the Verkhovna Rada (Ukrainian parliament) canceled the return from Eastern European Summer Time to Eastern European Time. On 18 October 2011, the Parliament abolished these plans. On 29 March 2014, after annexation by Russia, Crimea switched from Eastern European Time (UTC+02:00) to Moscow Time (UTC+04:00 then, subsequently changed to UTC+03:00). On 26 October 2014, the self-proclaimed proto-states of Donetsk People's Republic and Luhansk People's Republic also switched to Moscow Time.
