The answer is yes, Arizona does have its own time zone but with an exception of the Navajo Nation.
Arizona operates on its own time zone known as Mountain Standard Time (MST) throughout the year. Unlike most states in the United States, Arizona does not observe Daylight Saving Time (DST).
This means that the time in Arizona remains consistent throughout the year without the one-hour forward or backward adjustments that many other states experience when DST starts or ends.
This unique approach to timekeeping is because of the state's hot desert climate where the main goal is to minimize the need for additional energy consumption associated with DST changes.
