Daylight saving time in the U.S. last changed in 2007, when the start and end dates were shifted by the Energy Policy Act of 2005.

Key change in daylight saving time rules

  • In 2005, the U.S. Congress passed the Energy Policy Act, which extended daylight saving time by about four weeks.
  • Starting in 2007, daylight saving time began on the second Sunday in March and ended on the first Sunday in November instead of the old April–October schedule.
  • Those rules are still in effect in 2026: for example, in 2026 DST runs from March 8 to November 1 in the U.S.

Brief history so your question makes sense

  • Daylight saving time in the U.S. was standardized in 1966 by the Uniform Time Act, which set common start and end dates nationwide (with some opt-outs like Arizona and Hawaii).
  • Before 1966, states and even cities followed their own daylight saving schedules, which created a lot of confusion.
  • The 2005/2007 change is the “recent” one most people mean when they ask “when did daylight savings change?” because it’s when we moved to the current March–November pattern.

If you meant “when does it change this year?”

  • In 2026, clocks “spring forward” into daylight saving time on Sunday, March 8 at 2:00 a.m. local time in the U.S.
  • They “fall back” to standard time on Sunday, November 1 at 2:00 a.m. local time.

Forum / trending angle

A lot of recent forum discussions and news posts circle around whether to:

  1. Keep the current twice-a-year clock change.
  2. Switch to permanent standard time.
  3. Switch to permanent daylight saving time (so no more clock changes, just “later” sunsets all year).

You’ll often see people argue that changing the clocks disrupts sleep and may affect accidents or health, while others like the extra evening light for commuting and recreation.

TL;DR: The big modern change was set by the 2005 Energy Policy Act and took effect in 2007, moving U.S. daylight saving time to the second Sunday in March and the first Sunday in November, a system still used in 2026.
