MIAMI (CBSMiami) — In a sleep deprived nation, we’ve just lost a little more thanks to the arrival of Daylight Saving Time.

This means the daylight will begin later in the morning and the sun will set later in the evening.

Daylight Saving Time begins at 2:00 a.m. on the second Sunday in March and reverts to Standard Time on the first Sunday in November.  So the lost hour will return Sunday, November 3rd, when clocks go back to standard time.

The only two states that do not observe daylight-saving time are Arizona and Hawaii. Neither does American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands.

Of course, whenever you set your clocks ahead one hour, you are also supposed to make another change. Change the batteries on your smoke detectors.

Smoke detector batteries need changing every six months and the switch to daylight-saving time is the perfect time to make the change.

The Florida Highway Patrol also warns drivers and pedestrians to be especially careful on the Monday morning commute to work or school. It will likely be dark and everyone needs to pay close attention to the roads.

Did you know? Daylight saving time was first used during World War I, as part of an effort in the United States and other warring countries to conserve fuel. In theory, using daylight more efficiently saves fuel and energy because it reduces the nation’s need for artificial light.
