Arizona does not adhere to a fixed time zone the way most states do. Instead, most of the state remains on Mountain Standard Time (MST) year-round, effectively aligning with Pacific Daylight Time (PDT) during daylight saving time, as it does not observe DST. This means Arizona is neither strictly UTC nor ET but is UTC-7 during standard time.
