What states don't use Daylight Saving Time?

As Americans get ready to change the hour on their clock, not everyone in the US needs to worry about what the right time will be when Daylight Saving ends.

What states don't use Daylight Saving Time?

Twice a year the majority of Americans change their clocks for Daylight Saving Time. The change happens on the second Sunday of March and the first Sunday of November each year. The shift is always done on the weekend at 2:00 am to limit the amount of disruption caused. On Sunday 7 November most Americans will have to remember to change the hour on their clock, and enjoy an extra hour in bed.

There is a saying to help remember which way to change your clock, “Spring forward, Fall back,” so in the springtime you turn your clock forward one hour and in the autumn you turn your clock back an hour. However, there are parts of the US that don’t have to worry about what time it will be when they wake up because where they live there is no Daylight Saving Time.

Residents in some states will not be changing their clocks

For some the twice annual time change is a bother, which has led to calls to end the practice of Daylight Saving Time. 29 states have introduced legislation to do away with the twice-yearly switch, but it is contingent on neighboring states to do the same. However, the ultimate authority to do so has been under the Department of Transportation since 1966.

The only parts of the US that do not have Daylight Saving Time are Hawaii, most of Arizona, Puerto Rico, the US Virgin Islands, Northern Mariana Islands, Guam, and American Samoa.

Arizona experimented with the change beginning in 1918, but decided to permanently opt out of the Daylight Savings Time in 1968. Although the state observes Standard Time, the Navajo Nation, a Native American territory in the north-east of the state, which also crosses over into New Mexico and Utah, does make the twice a year time shift.

Hawaii is the only other state that currently doesn’t observe Daylight Saving Time, along with the other US territories in the Pacific and the Caribbean Sea. Since they are close enough to the equator that there is no significant difference in sunrise and sunset times across the year there are no benefits from changing the hour.

Why we change the clocks for Daylight Saving Time

The first person credited with suggesting the idea of changing our clocks to take advantage of the longer summer days was Benjamin Franklin while he was living in Paris. But the man credited with getting the ball rolling was a British builder named William Willett who suggested the idea to Parliament as a way for the nation as a whole to make better use of daylight.

However, Germany was the first to implement the practice of seasonal time changes, desperate to save energy during the First World War. The policy quickly caught on with most European nations, the US and the United Kingdom along with its allies adopting the Daylight Saving Time by 1918. However, many nations ditched the system in the years after the war only to adopt it again when there was a need to conserve energy.

Does Daylight Saving Time really conserve energy?

The Daylight Saving Time is credited with reducing crime, people are doing activities in the daylight so there are less opportunities for criminals, as well as saving lives and preventing traffic accidents. However, the primary reason for the twice-yearly shift comes from the energy savings it is purported to have. According to the US Department of Transportation study in 1975, the US experienced nearly a one percent daily savings on energy use during the yearly Daylight Savings Time period.

However, those findings have been contradicted by more recent analysis performed in 2006 when Indiana implemented Daylight Saving Time statewide, previously it had been in effect in just a few counties. Researchers found that residential energy consumption actually increased by around one percent. They ventured that although less lighting is needed, the longer summer evenings caused a spike in AC usage in households throughout the state.

The official end to summer is well in the rearview mirror and the days grow shorter as winter sets in. Remember, if you live in a part of the US that has Daylight Saving Time, on Sunday 7 November to turn back your clocks one hour, 2:00 am will become 1:00 am. You can do so Saturday before you go to bed or when you wake up. That is, unless you don’t mind arriving an hour early to whatever appointment you have the next day.
