When March arrives, much of the United States moves its clocks forward to daylight saving time. However, in Arizona the story is different: the state does not change its clocks and remains on standard time year-round. While in most of the country Daylight Saving Time begins on the second Sunday of March at 2:00 am, meaning clocks are moved forward at 3:00 am, in Arizona there is no need to move hands or adjust devices. The state remains in the Mountain Standard Time (MST) zone without observing the seasonal time change. Why doesn't Arizona change its clocks for the summer? Arizona decided not to adopt Daylight Saving Time in 1968, and the main reason is related to the climate. During the hottest months, especially in cities like Phoenix or Tucson, temperatures can easily exceed 40 degrees Celsius. Maintaining more sunlight in the afternoon would mean extending the intense heat into later hours of the day. By keeping standard time, the state seeks to reduce energy consumption associated with air conditioning use at night and avoid prolonged periods of heat. The exception within the state: However, there is one exception: the Navajo Nation, which extends across parts of Arizona, Utah, and New Mexico, does observe daylight saving time to maintain administrative consistency with the other territories where it has jurisdiction. This means that, within Arizona, there may be time differences in certain areas for several months of the year. In conclusion: there is no time change. It is not necessary to move your clocks forward or backward. However, it is important to keep in mind some practical aspects:

Like Arizona, Hawaii, American Samoa, Guam, the Mariana Islands, Puerto Rico, and the Virgin Islands also do not change their clocks.
