MIAMI (CBSMiami) — In a sleep deprived nation, we’re all about to lose a little more as Daylight Saving Time arrives Sunday. This means the daylight will begin later in the morning and the sun will set later in the evening.

So this is your reminder: Before going to bed Saturday night, move your clocks and watches forward by one hour or risk being an hour late to Sunday church or other activities.

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. Here’s why Arizona will not:

Neither does American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands.

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.

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.
