Officially, the change starts Sunday at 2 a.m. local time, though you are encouraged to set your clock ahead before going to bed Saturday night. While you will lose an hour of sleep tonight, you will gain an hour more of evening sunlight for any activities you may have planned over the next several months.
In addition to changing your clocks, it is recommended that you also use this time as a reminder to change the batteries in your warning devices such as your smoke detectors, carbon monoxide detectors and weather radios.
You may have noticed the annual tradition of Daylight Saving Time has crept forward a bit.
We used to spring forward on the first Sunday in April and fall back on last Sunday in October. But a couple years ago, Congress changed the date, adding more Daylight Saving Time to the calendar.
This year, it will run from March 10 until Nov. 3.
Not every place makes the switch. The exceptions are Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
Around the world, about 75 countries and territories have at least one location that observes Daylight Saving Time, according to TimeandDate.com. On the other hand, 164 don't observe the time change at all.
