<Tr> <Td> light green </Td> <Td> Further - eastern European Time / Moscow Time / Turkey Time (UTC + 3) </Td> </Tr> <P> European Summer Time is the variation of standard clock time that is applied in most European countries, not including Iceland, Georgia, Azerbaijan, Belarus, Turkey and Russia--in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, in order to make the most efficient use of seasonal daylight . It corresponds to the notion and practice of "daylight saving time" to be found in many other parts of the world . </P> <P> European Summer Time begins at 01: 00 UTC / WET (02: 00 CET, 03: 00 EET) on the last Sunday in March and ends at 01: 00 UTC (02: 00 WEST, 03: 00 CEST, 04: 00 EEST) on the last Sunday in October each year; i.e. the change is made at the same absolute time across all time zones . </P> <P> Greenland, except for the northeastern coast around Danmarkshavn (UTC year - round), observes Summer Time simultaneously with Europe, except for Thule Air Base (which follows Atlantic Time and observes in accordance with Canadian rules). Summer Time thus begins at 00: 00 East Greenland Time and Saturday 22: 00 West Greenland Time, and ends 01: 00 EGST and Saturday 23: 00 WGST . </P>
