Daylight Saving Time Starts Tonight: What You Need To Know...

Millions of Americans will lose an hour of sleep tonight as daylight saving time begins at 2 a.m. Sunday, March 8, 2026. The annual time change is trending as people prepare to adjust their clocks and debate the controversial practice's future.

Clocks will spring forward one hour in most U.S. states except Hawaii and Arizona (excluding Navajo Nation). The shift means more evening daylight but darker mornings until November 1, when standard time resumes. Many digital devices will update automatically, but manual clocks and appliances need adjustment.

The time change coincides with increased legislative action nationwide. At least 19 states have passed bills to make daylight saving time permanent if federal law changes, according to the National Conference of State Legislatures. The Sunshine Protection Act, reintroduced in Congress last month, would eliminate seasonal time changes nationwide.

Sleep experts warn the transition can disrupt circadian rhythms for days. The American Academy of Sleep Medicine recommends gradually adjusting bedtime and maximizing morning light exposure. Studies show a 6% increase in fatal car crashes the week after the time change, per University of Colorado research.

Public opinion remains divided. A 2025 YouGov poll found 62% of Americans favor ending seasonal time changes, with 50% preferring permanent daylight saving time. Critics argue the practice causes unnecessary health and safety risks with minimal energy savings.

Fire departments nationwide use the time change as a reminder to check smoke detector batteries. Many businesses adjust operations accordingly, while airlines account for schedule changes in flight planning. The time shift also affects stock market openings and TV broadcast schedules.

As clocks change tonight, lawmakers continue debating whether this could be one of the last spring transitions. For now, Americans should prepare for shorter sleep and brighter evenings until fall.
