Overview
- Most Americans move clocks ahead one hour at 2 a.m. local time on Sunday, March 8, starting Daylight Saving Time for participating states.
- Hawaii, most of Arizona (except the Navajo Nation), and U.S. territories including Puerto Rico and the U.S. Virgin Islands do not observe the change.
- British Columbia advances clocks on March 8 and then keeps daylight time year‑round under a new Pacific Time alignment, joining jurisdictions like Saskatchewan and Yukon in ending seasonal shifts.
- Congress has not approved nationwide permanent time: the Senate passed a permanent‑DST bill in 2022, the House has not voted, states have adopted contingent measures, and a new proposal would split the difference by moving clocks 30 minutes.
- Sleep and safety research links the spring change to short‑term harms such as more crashes and cardiovascular events, while polling shows broad frustration with clock changes but division over adopting permanent daylight or permanent standard time; Alberta is launching consultations on a possible switch.
