Why don't some states observe daylight savings time?

Not sure about this, but it may be because some are sovereign states.

Meaning they are independent from some Federal Laws.

This is because the further south you go (and Hawaii is the southernmost state), the less difference there is between the length of day at the summer and winter solstices. The logic behind DST kind of loses traction in those circumstances.

Arizona is the only other state to not observe DST, but neither do Puerto Rico, the US Virgin Islands, or American Samoa.

Because they’re smarter than us.

I lived in Arizona for many years and was confused year ‘round about how far behind or ahead of other time zones we were.

Here’s why Arizona hasn’t observed DST since 1967, according to Wiki:

“This is in large part due to energy conservation: Phoenix and Tucson are hotter than any other large U.S. metropolitan area during the summer, resulting in more power usage from air conditioning units and evaporative coolers in homes and businesses. An extra hour of sunlight while people are active would cause people to run their cooling systems longer, thereby using more energy. Local residents remember the summer of 1967, the one year DST was observed. The State Senate Majority leader at the time owned drive-in movie theaters and was nearly bankrupted by the practice. Movies could not start until 10:00 PM at the height of summer: well past normal hours for most Arizona residents.”

Each state gets to decide independently. Personally, I think it’s pretty weird that Daylight Savings Time is what we do most of the year, and “Standard” time is only about ⅓ of the year… but who am I to say?

There are a lot of countries that don’t change their clocks, too. It’s not necessary, but it can make sense from a regional perspective.

Arizona is absurd. Even Arizona has exceptions: The Navajo nation. They do observe it. Now it gets totally absurd. The Hopi with their own land inside the Navajo land do not observe it.

What’s next? Maybe the people of Phoenix decide to observe it. But then the people in Phoenix who live north of Buckeye Rd and west of Central Avenue decide not to observe it. Must I go on?

Bottom line: Standards make sense. Arizona’s stance is unacceptable and quite ignorant when it comes to business travelers or tourists visiting their state. It’s kind of a childish ‘not invented here’ protest.

@mattbrowne Hm. I wonder if we can legally decide, for ourselves, when and when not to observe the time change. Just think how often I could be late for work, or leave early with no repercussions!

@Dutchess_III – Great idea. Next year our house will observe DST, but our master bedroom won’t. My wife will loves this!

O boy! My head is spinning already @mattbrowne!
