The end of Daylight Saving Time (a.k.a. Summer Time) in 2013:
In 2009 the UK will change their clocks one hour ahead at 1am on the last Sunday in March, March 29th. They will move their clocks back an hour at 1am on the last Sunday in October, October 25th.
SPRING forward, FALL back. SPRING forward, FALL back.
November 3rd
because the day is longer now
Yes, clocks fall back one hour
Clocks get turned BACK one hour - an easy way to remember this operation is "Spring Forward, Fall Back."
When you turn the clocks back, you are adjusting them to reflect a different time zone or to correct for daylight saving time ending. This practice typically occurs in the fall to "fall back" one hour.
Clocks are set back one hour when Daylight Savings Time ends, typically in the fall. When the time changes from Daylight Saving Time to Standard Time, people usually "fall back" and set their clocks back one hour.
Clocks are typically set back one hour at 2:00 am local time on the first Sunday in November for countries observing daylight saving time. This practice is to mark the end of daylight saving time in the fall.
"Fall back" is a sort of mnemonic designed to remember the time changes that come with Daylight Savings in autumn. In fall, one turns back their clocks one hour -- analogous to "falling back" one hour. Compare this to spring where the clocks "spring ahead" one hour.
In the fall of 2010, the clocks were turned back on November 7th. This is part of the daylight saving time practice where clocks are set back one hour to mark the end of daylight saving time for the year.
"Spring ahead, fall back."
