The United States officially adopted Daylight Saving Time (yes, not “Savings”) as part of the Uniform Time Act of 1966. Before that, states could come up with their own versions of the practice. In fact, Iowa once had 23 different pairs of start and end dates throughout the state. This new law brought much needed order to the country’s clocks, but it didn’t require all states to comply. And so, two states eventually opted out: Hawaii and Arizona.
Hawaii abandoned the law in 1967 because, well, it just didn’t make sense. One of the benefits of Daylight Saving Time is that there’s more daylight in the evening. But in Hawaii, the sun rises and sets at about the same time every day
