Most countries in Europe will end daylight saving time (DST), also known as “summer time”, on Sunday, October 25, 2009. The clocks will turn back by one hour in many cities including Athens, Berlin, London, Moscow, Madrid, Paris, and Rome.

It is also important to note that Russia’s Kemerovo oblast will not apply its new time zone until March 28, 2010. Moreover, Mexico’s daylight saving schedule also ends on Sunday, October 25, 2009.

Europe’s daylight saving schedule runs from the last Sunday of March until the last Sunday of October. An EU (European Union) directive states that the last Sundays of March and October would be the dates definitively adopted for the daylight saving schedule among EU countries.

Daylight saving time starts and ends at 1am (01:00) UTC in many countries in Europe, which enables these countries to change their clocks at the same global time but in different local times.
