Daylight Saving Time 2024: Start and End Dates Announced

As daylight saving time approaches, Americans prepare for longer days and debates over its permanence continue.

Daylight saving time will begin on Sunday, March 10, 2024, at 2 a.m. local time and end on Sunday, November 3, 2024.
The transition to daylight saving time is linked with negative health effects, including increased heart attacks and teen sleep deprivation.
A growing number of states support adopting permanent standard time, citing closer alignment with natural light cycles.
Not all U.S. states and territories observe daylight saving time, with Hawaii and Arizona among the exceptions.
Legislative efforts to make daylight saving time permanent have stalled, but the debate over its benefits and drawbacks persists.
