We're all about to get hit with an extra hour of daylight — and docked one hour of sleep. daylight saving time, the practice of pushing the clocks forward one hour during spring and summer months to take advantage of natural daylight, will commence in the United States Sunday at 2 a.m. Eastern. We regain the hour when daylight saving time ends in the fall. 

Daylight saving time was first implemented in Canada in 1908 to extend the window of natural daylight while we're awake and conserve energy, according to Time and Date. Germany was the first country to implement Daylight Savings Time to save energy to convert to fuel for World War I. The practice was introduced in the U.S. a couple years later for the same purpose. It was repealed a few months later until President Franklin D. Roosevelt officially implemented it as an annual practice in 1942.

Don't worry, your smartphone will automatically adjust.

Bonus: The Southern Hemisphere practices Daylight Savings Time in September as its seasons are flipped.
