On March 8, 2026, the United States transitions to Daylight Saving Time, when clocks spring forward an hour at 2 a.m. to read 3 a.m., a practice aimed at making better use of daylight during the warmer months. While this time change is widely adopted across most of the country, there are notable exceptions where certain regions have opted out of this annual adjustment.

Hawaii and most of Arizona are significant examples of U.S. jurisdictions that do not observe Daylight Saving Time, maintaining the same time year-round. These regions have chosen to forgo the time change primarily due to geographical and climatological factors, which lessen the perceived benefits of adjusting clocks. Such decisions highlight the diversity in how timekeeping practices can vary across different areas of the country.

The lack of uniformity in observing Daylight Saving Time can lead to confusion for travelers and businesses operating across state lines. Understanding which areas do not participate in this practice is essential for accurate scheduling and planning. As U.S. states continue to debate the effectiveness and necessity of Daylight Saving Time, some may consider following Hawaii and Arizona's example, reflecting ongoing discussions about time management in light of modern lifestyles.
