We'll gain an extra hour this weekend as Daylight Saving Time officially ends on Sunday, November 5, 2023 at 2:00 AM. That's when we'll turn our clocks back one hour (spring forward; fall back) to Standard Time. Before you go to bed on Saturday night or when you get up on Sunday morning, be sure to set your clocks back an hour.
Daylight Saving Time (and yes, it is "SAVING", not savings or saving's) begins on the 2nd Sunday of March and ends on the 1st Sunday of November. It 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 the lights in your house.
All states in the U.S. (and more than 70 countries worldwide) observe daylight saving time except Hawaii and Arizona. Neither do the U.S. territories of American Samoa, Guam, Northern Marina Islands, Puerto Rico, and Virgin Islands.
Daylight saving time will end on Sunday, March 10, 2024 at 2:00 a.m. when we will “spring forward.”
