Daylight Saving Time to Begin March 9, Sparking Renewed Debate Over Its Future

As Americans prepare to set clocks forward, calls to end the biannual time change gain momentum amid health and legislative concerns.

Daylight saving time starts on Sunday, March 9, 2025, at 2 a.m., with clocks moving forward by one hour until November 2.
The practice, originally introduced during World War I to conserve energy, has been federally standardized since 1966 but remains contentious.
Health experts warn of increased risks of sleep deprivation, heart issues, and circadian rhythm disruptions linked to the time change.
A majority of Americans support ending the clock-changing practice, with 19 states passing legislation to adopt permanent daylight saving time pending federal approval.
The Sunshine Protection Act, which would make daylight saving time permanent, has stalled in Congress despite bipartisan support and recent reintroduction.
