Daylight saving time ends Sunday. Here’s what to know and how to ease the change

Daylight Saving Time Ends Sunday

Most of America will set clocks back one hour at 2 a.m. Sunday, returning from daylight saving time to standard time. This shift began on March 9, 2025, when clocks were moved forward by one hour.

History and Public Opinion

Daylight saving time started in 1918 to conserve fuel during World War I. Since then, its popularity has decreased, with a recent AP-NORC poll showing 47% of adults oppose it, while others still support the system.

Currently, all states except Arizona and Hawaii observe daylight saving time and will adjust their clocks this Sunday.

How to Ease the Transition

Kenneth Lee, a neurologist and medical director of the University of Chicago Medicine’s Sleep Center, advises gradually shifting bedtime earlier by 15 to 20 minutes a few nights before the change.

Adjust clocks on Saturday evening to help the body acclimate.
Align meals and coffee consumption with the adjusted bedtime.
Avoid extra caffeine as it may disrupt sleep.

“People should begin pushing back their bedtime by 15 to 20 minutes a few nights before Sunday,” Lee said.

Lee also recommended the same gradual adjustment for young children, advancing the clock early and shifting bedtime incrementally.

Summary

Expert advice suggests adopting gradual bedtime changes and adjusting daily routines ahead of the time shift to minimize disruption and ease the return to standard time.
