Which two U.S. states do not observe Daylight Saving Time? Explained
In the United States, the only two states that remain on standard time throughout the entire year are Arizona and Hawaii. Hawaii made the decision to stop observing the clock change in 1967 because its proximity to the equator means there is very little difference between the amount of daylight in the summer and winter. For Hawaiians, shifting the clocks would provide no tangible benefit, so they maintain a consistent schedule that aligns with their tropical environment and natural sun cycles.
