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.

For the past four months, we’ve been on standard time. But overnight Saturday, we’ll turn our clocks ahead one hour at 2 a.m., effectively making it 3 a.m. (So don’t schedule any important meetings at 2:30 a.m., because that time won’t exist Sunday — and is not a great time for a meeting, anyway).

It's time to "spring forward." Daylight Saving Time begins this month. Here's everything you need to know about the seasonal practice.

Staying on daylight saving time permanently would also mean no more 4:30 p.m. sunsets, even in the middle of winter. So, the earliest sunsets we'd have in late December and early January would be around 5:30 p.m.

This year, 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.

Daylight saving time is set to start in a few days. See why most of the U.S. observes it and when it starts and ends in California.

Doctors say that while it's good to have an extra hour of sunlight, the time change can also cause sleep deprivation and other health problems.

Daylight Saving Time (DST) takes place each year on the second Sunday of March until the first Sunday in November. While we “spring forward” in March, in November, the clocks “fall back” and we gain an extra hour of sleep overnight.

And, beginning in 1967, the act mandated Standard Time within the established time zones and provided that clocks would be moved ahead one hour beginning at 2 a.m. on the last Sunday in April and turned back one hour at 2 a.m. on the last Sunday in October.
