Prior to 2007, those acknowledging Daylight Saving Time were typically setting their clocks back an hour in October.

This year, DST ends at 2 a.m. Sunday, Nov. 5. Why is it so much later on the calendar?

When George W. Bush was president, the government changed the timing of the end of DST to coincide with the Energy Policy Act of 2005. That added four extra weeks to DST and moved the end to the first week of November.

State commissioners in Massachusetts are considering a proposal to move the state from the Eastern Time Zone to the Atlantic Time Zone year-round so that it will not follow Daylight Saving Time changes. Some are concerned with the time of the sunset — it can be as early as 4:11 p.m. in December in Boston ... leading to short, cold days as many haven't started their commutes home from work by then.

The state commission will vote Nov. 1 on whether to send the time change proposal to lawmakers.
