Arizona is an hour ahead due to its decision not to observe Daylight Saving Time (DST), except for the Navajo Nation. During DST, most of the United States moves their clocks forward an hour, effectively aligning with Arizona’s standard time. Once DST ends, these areas shift back an hour, making Arizona appear an hour ahead to those regions.
