The official spelling is Daylight Saving Time, not Daylight SavingS Time. Adding to the confusion - the phrase Daylight Saving Time is inaccurate, since no daylight is actually saved.
Daylight Shifting Time would be better. The idea of daylight saving was first conceived by Benjamin Franklin during his sojourn as an American delegate in Paris in 1784, in an essay, "An Economical Project."
Daylight Saving Time
Daylight Saving Time begins at 2:00 a.m. on the second Sunday in March (10th) and reverts to standard time on the first Sunday in November (3rd).
Spring Forward, Fall Back
During DST, clocks are turned forward an hour, effectively moving an hour of daylight from the morning to the evening. In spring, clocks spring forward from 2:00 a.m. to 3:00 a.m.; in fall, clocks fall back from 2:00 a.m. to 1:00 a.m.
Is it hard for you to adjust to the "shift"?
Did you know that it is regulated by the Department of Transportation?
