Many people have been wondering when Daylight Saving Time (DST) Â is scheduled for this fall.Â Mark your calendars (if they arenâ€™t already) for Sunday, November 1, 2009, at 2 a.m.
There has been some confusion about the â€œfall backâ€ time for DST 2009. In the past, the time change happened on the last Sunday in October. The time change now happens on the first Sunday in November.
Remember to change your clocks, but be careful as some clocks on cell phones, computers, etc., are programmed to change automatically for DST.Â Also, to add more confusion, some computers and electronic devices may haveÂ already been programmed to change on the last Sunday in October.Â So double-check that your clocks have the correct time.
So what is DST? Here is a description from TimeandDate.com:
Daylight Saving Time (or summertime as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer. During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer.
The reason DST works is because its saves energy due to less artificial light needed during the evening hoursâ€”clocks are set one hour ahead during the spring, and one hour back to standard time in the autumn. Many countries observe DST, and many do not.
Note: Between Marchâ€“April through Septemberâ€“November, it is summer in the northern hemisphere, where many countries may observe DST, while in the southern hemisphere it is winter. During the rest of the year the opposite is true: it is winter in the northern hemisphere and summer in the southern.
Benjamin Franklin first suggested Daylight Saving Time in 1784, but it was not until World War I, in 1916, when it was adopted by several counties in Europe that initially rejected the idea.
It is difficult to predict what will happen with Daylight Saving Time in the future. The daylight saving date in many countries may change from time to time due to special events or conditions.The United States, Canada and some other countries extended DST in 2007. The new start date is the second Sunday in March (previously the first Sunday in April) through to the first Sunday in November (previously the last Sunday in October).
