Daylight Saving Time Ends Sunday, November 2, 2025
On Sunday, November 2, 2025, Americans will set their clocks back one hour at 2 a.m., marking the end of daylight saving time. This adjustment gives residents an extra hour as standard time returns until spring.
Regions Not Observing the Change
- Hawaii
- Most of Arizona
- Several US territories
These areas do not participate in the twice-yearly clock changes.
Legislative Background
Although the Senate passed legislation for permanent daylight saving time in 2022, the bill has stalled in Congress and has not yet been enacted.
Impact of the Time Change
The fall time adjustment means clocks will read 1 a.m. twice as they move back one hour, opposite to spring when an hour is lost by skipping from 1:59 a.m. to 3 a.m. Instead, Sunday morning's change adds an hour by turning clocks from 1:59 a.m. back to 1 a.m.
Earlier sunsets will be noticeable nationwide as autumn turns to winter. Standard time remains until the next daylight saving period begins on March 8, 2026, running until November 1, 2026.
Historical Context
The Standard Time Act of 1918 established this system to maximize summer daylight by postponing sunset an additional hour.
