The fluctuating weather may not be an indicator that spring is on its way, but it's that time of year again where clocks jump forward an hour--leading to noticeably brighter mornings and longer days.
At 2 a.m. Sunday (March 12), the clocks spring ahead forward an hour, according to the Washington Post. That means you'll be greeted with more daylight while leaving work due to a later sunset, around 7 p.m. or later.
There's not so good news for early risers. Daylight savings also comes with later sun rises so you'll probably want to schedule that early run to after work.
Not all parts of the United States, however, are affected. Hawaii and Arizona, besides the Navajo Nation, do not observe daylight saving time along with the U.S. territories U.S. territories of American Samoa, Guam, Puerto Rico, the Virgin Islands and the Northern Mariana Islands.
(Yeah, we know, it's confusing.)
WATCH | National Geographic breaks down daylight saving time
Many may wonder why someone would ever impose a schedule change that costs us a precious hour of sleep, but daylight saving time served a greater purpose during the days of World War I, according to the History Channel.
The concept was first proposed by Englishman William Willett, who wanted to spring clocks forward between April and October so that people could enjoy more sunlight, and conserve energy. He went as so far to publish a 1907 brochure called "The Waste of Daylight."
Unfortunately, his efforts were consistency stymied by Parliament. But when WWI hit, Germany, on April 30, 1916, became the first country to embrace daylight saving time to conserve electricity. The United Kingdom soon followed.
