States that don't observe DST

🌵 Arizona

Arizona has opted out of Daylight Saving Time since 1968 and stays on Mountain Standard Time. The Navajo Nation, in the north-east corner of the state, is the exception and does change its clocks.

🏝️ Hawaii

Hawaii has not changed its clocks since 1967. Being close to the equator, its daylight hours barely vary through the year, so DST offers no benefit.

The US territories — Puerto Rico, Guam, American Samoa and the US Virgin Islands — also stay on standard time year-round.
