These States Won’t Change Clocks for Daylight Saving Time – Here’s Why

As the colder months approach and daylight hours diminish, many regions prepare for the usual end of daylight saving time. However, not all U.S. states will participate in this biannual clock adjustment. A few states and U.S. territories will maintain the same time throughout the year, opting out of the practice entirely. 

Arizona (excluding the Navajo Nation) and Hawaii are among the states that do not observe daylight saving time. Additionally, U.S. territories such as Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands also choose not to adjust their clocks.

U.S. Territories That Do Not Change Their Clocks

Puerto Rico:

As a Caribbean territory, Puerto Rico is located at a latitude similar to Hawaii, where daylight duration varies minimally throughout the year. Thus, it does not follow daylight saving time.

Guam:

This Pacific territory remains on standard time year-round. Like other island territories, the minimal daylight variation does not justify changing clocks.

American Samoa:

Situated in the South Pacific, American Samoa remains on standard time, similar to Guam and Puerto Rico.

U.S. Virgin Islands:

Located in the Caribbean, these islands also avoid daylight saving time because there is minimal variation in daylight hours.

Why Some Regions Abandon Daylight Saving Time

Certain regions opt out of changing their clocks twice a year for various reasons. For instance, states like Arizona and Hawaii, which are closer to the equator, receive relatively consistent sunlight throughout the year. This stable amount of daylight reduces the need for the adjustments associated with daylight saving time.

Keeping a consistent time year-round has several health and energy-saving benefits. Research suggests that a year-round standard time better aligns with the human body’s natural circadian rhythm, promoting healthier sleep patterns. In addition, some officials argue that eliminating the need to change clocks could potentially reduce energy consumption. As some advocates have pointed out, the practice is increasingly seen as outdated and unnecessary.

Debates continue about the usefulness of daylight saving time. Some states and territories have opted out, while others are considering making it permanent, pending federal approval. As discussions progress, time management practices may continue to evolve across the country.
