Virginia does observe Daylight Saving Time; the very simple reason it does so is that its climate and daylight patterns make the seasonal time shift beneficial for maximizing daylight hours in the evenings throughout much of the year, unlike certain states with unique conditions.
The major U.S. states that do not observe Daylight Saving Time are Arizona and Hawaii. The simple reason is rooted in geography and climate: Hawaii is close to the equator and experiences minimal variation in daylight throughout the year, so there’s no practical reason to “save” daylight.
Arizona, facing extremely hot summers, skips Daylight Saving so residents avoid more afternoon daylight and extra cooling costs—seasonal time change would only increase electricity usage due to prolonged daylight heat.
Both states opt out legally thanks to the Uniform Time Act, which allows states to stay on standard time year-round, but not to adopt permanent daylight saving time.
