Daylight Saving Time Ends 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, according to NBC News. This annual change, which started on March 9, provides an extra hour as standard time returns until spring.
Areas Without the Change
Hawaii, most of Arizona, and several U.S. territories do not observe the twice-yearly clock adjustment.
Legislative Background
Although the Senate passed a bill to make daylight saving time permanent in 2022, the legislation did not advance through Congress.
What Happens During the Change
- At 2 a.m. on Sunday, clocks will roll back to 1 a.m., effectively repeating the 1 a.m. hour.
- This shift contrasts with the spring forward change, where clocks jump ahead from 2 a.m. directly to 3 a.m., losing an hour.
- As a result, people gain one additional hour this morning.
"Sunday morning brings an hour gain, with clocks reversing from 1:59 a.m. to 1 a.m.," NBC News reported.
Seasonal Effects
Following the change, sunset times will grow earlier nationwide as autumn transitions into winter. Standard time remains in effect until daylight saving returns in spring 2026.
Next Daylight Saving Period
The upcoming daylight saving time period starts on March 8, 2026, and ends on November 1, 2026.
Historical Context
The Standard Time Act of 1918 established daylight saving time to extend summer daylight hours by shifting sunset later by one hour, based on information from the US Naval Observatory's Astronomical Applications Department.
"This system...was established to maximize summer daylight by postponing sunset an additional hour," cited from the US Naval Observatory via NBC News.
Summary
Each November, the shift back to standard time grants an extra hour of morning light, balancing seasonal daylight changes until spring reinstates daylight saving.
