Daylight Savings Time 2009: Fall Back Nov. 1

Just a reminder that Daylight Savings Time 2009 ends late for the third year in a row, on November 1st at 2am.  On that night, clocks go back one hour.

Remember, you do NOT need to do this if you live in Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands or American Samoa – and if you don’t live in the U.S. of course.

The law extending Daylight Saving Time by four weeks was passed in 2007.

Daylight saving time (DST) or summer time (British English), is the widespread practice of advancing official clock time so that afternoons have more daylight and mornings have less.

Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. Modern DST was first proposed in 1895 by George Vernon Hudson, a New Zealand entomologist. Many countries have used it since then. Details vary by location and change occasionally.
