Daylight Saving Time

The US Congress extended Daylight Savings Time to begin earlier and end later each year, starting this year. DST used to begin on the first Sunday in April and end on the last Sunday in October. It will now begin on the second Sunday in March and end on the first Sunday in April.

DST is supposed to help save energy. This story says that since the energy savings may be negligible, the extended DST may be rolled back, within an year.
