Spring ahead — When Daylight Saving Time 2017 begins
Daylight Saving Time 2017, when you move your clocks ahead, is Sunday March 12.
Daylight Saving Time, otherwise known as when we "spring ahead," begins at 2 a.m. on Sunday March 12, 2017. Most clocks, such as those on cell phones and computers will update automatically overnight, moving forward from 2am to 3am. But other household clocks such as those on alarm clocks, microwaves, stoves and car radios have to be manually updated.
Daylight Saving Time makes better use of the daylight in the evening by moving the clocks ahead one hour during the longer days of late spring and summer. Daylight Savings Time will end and "Fall back" on Sunday November 5, 2017.
Not every state moves their clocks ahead to observe Daylight Saving Time. The federal government does not require its states or territories to observe DST, states such as Arizona and Hawaii, as well as places like Puerto Rico, Virgin Islands, Guam and American Samoa, do not adjust their clocks.
Daylight Saving Time can also be a perfect reminder to change the batteries in your smoke alarms around your home to ensure they work in the event of an emergency.
