Daylight Saving Time Begins March 10 Across Most of the U.S..

As clocks spring forward, efforts to make daylight saving time permanent face legislative hurdles.

Daylight saving time (DST) begins on March 10, 2024, at 2 a.m. local time, marking the transition to longer days and later sunsets across most of the U.S.
The change aims to shift an hour of daylight from the morning to the evening, originally implemented as an energy-saving measure during World War I.
Health studies indicate that the shift can disrupt human circadian rhythms, leading to sleep debt and potential safety hazards, such as increased risk of drowsy driving.
Legislative efforts to make DST permanent have stalled in Congress, despite bipartisan support and the introduction of the Sunshine Protection Act.
Some states have passed measures to remain on DST year-round, but federal approval is required for these changes to take effect.
