Daylight saving time (DST) is observed by most U.S. states, but a few have chosen to remain on standard time throughout the year. Here’s a look at which states and territories do not change their clocks and why.
Which U.S. States Do Not Observe Daylight Saving Time?
Hawaii: This island state does not observe daylight saving time due to its location near the equator, where daylight hours remain consistent throughout the year.
Arizona (except the Navajo Nation): Arizona stays on standard time year-round to reduce exposure to extreme heat during the hottest parts of the day, thus saving energy on cooling. However, the Navajo Nation within Arizona does observe daylight saving time to stay consistent with its territories in Utah and New Mexico.
U.S. Territories That Stay on Standard Time
Several U.S. territories also opt out of daylight saving time due to minimal changes in daylight duration throughout the year:
- Puerto Rico
- Guam
- American Samoa
- U.S. Virgin Islands
Why Some Choose Not to Observe Daylight Saving Time
The choice to remain on standard time is primarily influenced by geographic and climatic factors. Regions closer to the equator, such as Hawaii and U.S. territories in the Pacific and Caribbean, experience little variation in daylight hours, making the practice of changing clocks unnecessary. In Arizona, avoiding daylight saving time helps manage the state’s extreme heat more efficiently.
The Future of Daylight Saving Time in the U.S.
The debate on the usefulness of daylight saving time continues across the country. Several states have proposed making daylight saving time permanent, but such changes require federal approval. As this discussion evolves, we might see more states and territories reconsider their stance on daylight saving time.
By understanding which states and territories do not observe DST and their reasons, we gain insight into the diverse needs and preferences that shape time management practices across the U.S.
