Clocks will "spring forward" one hour at 2 a.m. on Sunday, March 9, 2025, causing most people to lose an hour of sleep. We won't "fall back" to standard time again until Nov. 2, the first Sunday of November, when Americans fiddle with their clocks again.

Daylight saving time could take effect for the last time on Sunday. Amid the federal government debating whether to keep daylight saving time or toss it for good, the clocks are leaping forward an hour yet again.

While all but two states in the U.S. continue to observe daylight saving time, there is still disagreement about whether it should be eliminated or made permanent.

It's once again time to spring forward this weekend as millions of Americans will change their clocks and get that extra hour of sunlight in the evenings.

A three-year congressional effort to make daylight saving time permanent in the United States appears to have halted, with President Donald Trump saying on Thursday that Americans are evenly divided over the issue.

This weekend, most of the United States will "spring forward," losing an hour of sleep to gain an hour of daylight.

Daylight saving time in the U.S. begins March 9, 2025. The practice of changing the clock started over 100 years ago in the United States, but many Americans don't like it or understand it, and some simply don't observe it.

What date does daylight saving time start? Do we gain or lose an hour in March? Will Trump end DST? What we know about when clocks spring forward in 2025.

Daylight saving time begins Sunday, March 9, with clocks rolling forward one hour at 2 a.m. With the change, it will stay lighter later in the evening across the United States. The first day of spring this year occurs March 20. When clocks "spring forward" to start daylight saving time, people lose one hour of sleep.

President Donald Trump has said that he intends to abolish Daylight Saving Time, which could have health and economic benefits.

Daylight saving time​ in 2025, when clocks change by an hour, is starting tonight. Here's a look at when exactly we "spring forward."

It wasn't until the passing of the Uniform Time Act of 1966 that daylight saving became permanent, which established time zones across the country. The act stated that clocks would advance by one hour at 2 a.m. on the last Sunday in April and turn back one hour at 2 a.m. on the last Sunday of October.
