The States and Territories
The following US states and territories do not observe Daylight Saving Time:

- Hawaii: Hawaii, like Arizona, also stays on its standard time, which is the same as Pacific Standard Time (PST).
- American Samoa: This US territory adheres to the Samoa Standard Time (SST) throughout the year, which is 11 hours ahead of Coordinated Universal Time (UTC).

- U.S. Virgin Islands: The U.S. Virgin Islands also follow Atlantic Standard Time (AST) and do not switch to Daylight Saving Time.
Why Don't They Change?
Several factors contribute to these states and territories' decision to opt out of Daylight Saving Time:
- Historical Reasons: Arizona, for instance, first adopted a standard time in 1918, and following an attempt to switch to Daylight Saving Time in 1967, the residents overwhelmingly voted to maintain Mountain Standard Time year-round.
- Energy Conservation: Some proponents argue that permanent standard time saves energy, as it aligns with the natural sunrise and sunset cycles, reducing the need for artificial lighting during peak hours.
- Health Considerations: Others cite potential health benefits, claiming that consistent time patterns promote better sleep and reduce disruptions to circadian rhythms.
- Agricultural Practices: Some states and territories with large agricultural sectors prefer a consistent time for livestock management and farming operations.
The Impact of Not Observing Daylight Saving Time
The decision to maintain standard time year-round has several implications:
- Time Differences: It can be confusing for people traveling to or from these states and territories, as the time difference with other states can change depending on the time of year.
- Business Operations: Businesses that operate across multiple time zones may face challenges in coordinating schedules and managing communication.
- Social Activities: Social schedules and leisure activities can be impacted, as the timing of sunrise and sunset remains consistent throughout the year.
Arizona: A Case Study
Arizona's experience with permanent standard time provides a compelling case study. The state has a long history of maintaining MST year-round, and while some concerns have been raised regarding potential economic drawbacks, many residents consider it a cherished part of their identity.
