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).

The spring equinox, also known as the vernal equinox, marks the official start of the season, which happens on Thursday, March 20, 2025.
