Daylight saving time will officially arrive at 2:00 a.m. on Sunday, March 12, 2023. Before you go to bed on Saturday night, turn your clocks ahead one hour or "Spring Forward". It's "daylight saving time" - no hyphen, no apostrophe and no extra S in the phrase.
According to timeanddate.com, "daylight saving time is the practice of setting the clocks one hour ahead of standard time to make use of more sunlight in the spring, summer, and fall evenings. Daylight Saving Time (DST) is used to save energy and make better use of daylight. It was first used in 1908 in Thunder Bay, Canada."
Daylight saving time became a national standard in 1966 when President Lyndon B. Johnson signed the Uniform Time Act, which was established as a way to continue to conserve energy. The thinking was, if it's light out longer, that's less time you'll need to use lights in your home.
In 2005, Congress amended daylight saving and extended the April to October period to the dates we know today — March to November.
In 2023, we will "fall back" on Sunday, Nov. 5th when we turn our clocks back one hour.
