Daylight Saving Time for 2025 begins in most parts of the United States at 2 a.m. on Sunday, with Americans losing an hour of sleep but gaining one of daylight.

In the spring, participating states turn clocks forward one hour on the second Sunday of March, causing us to spring forward and lose an hour of sleep. Clocks "fall back" on Sunday, Nov. 2. Daylight saving time ends on the first Sunday of November each year.

Daylight saving will kick off this weekend — and while modern technology has eliminated the need for you to adjust some of your devices — you'll still be responsible for changing a few.
