In 2025, Americans will “spring ahead” on Sunday, March 9, marking the end of standard time and the beginning of daylight saving time. At that time, clocks will jump ahead one hour from 2 a.m. to 3 a.m.

Winter is winding down as the sun sets later each day, but nothing says spring like the day we spring the clocks forward. Under the current daylight saving period, most Americans will lose an hour on the second Sunday of March and gain an hour on the first Sunday of November.

In March, millions of Americans will turn their clocks forward, marking the start of daylight saving time in 2025. The controversial practice of "springing forward" and "falling back" has been observed in most states for decades.

While most states follow the biannual practice, Arizona — with the exception of the Navajo Nation — and Hawaii do not partake in daylight saving time. The U.S. territories of Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands also forgo the twice-yearly changing of the clocks.

Here's when daylight savings time starts and ends this year and what would happen around the country if it ends permanently in 2025.

We’re still in the dark, cold days of winter but take heart. Spring – and the time change – is just around the corner.
