Daylight Saving Time 2017 begins at 2:00 AM on Sunday, March 12
Daylight Saving Time was introduced in the United States with the Standard Time Act of 1918 during World War I. This was a way to save energy for war production by taking advantage of the later hours of daylight between April and October. The federal government again required the states to observe the time change during World War II. Not until 1966 with the signing of the Uniform Time Act was the length of Daylight Saving Time standardized.
Arizona (except for the Navajo nation) and Hawaii, with the U.S. Virgin Islands, American Samoa and Puerto Rico have chosen not to switch to Daylight Saving Time, but remain on Standard Time through the year.
Today we use the terms “Spring forward” and “Fall back” to help us remember which way to turn our clocks – officially at 2 a.m. on the second Sunday in March and the first Sunday in November. For some it means remembering how to change their digital clocks – especially in some cars, and realizing it has already happened on their computer and cell phone when they awake.
The Fishers Island Fire District recommends the National Fire Protection Association guidelines: While you’re adjusting clocks for Daylight Saving Time this weekend, add one more, potentially critical task: swap out those smoke and carbon monoxide alarm batteries for fresh ones.
