Some states, like Arizona, don't change their clocks for daylight saving time.

The U.S. House of Representatives voted on Tuesday to make daylight saving time permanent, which would keep clocks set forward throughout the year. Supporters argue that this change provides necessary continuity and consistency in daily lives. Meanwhile, certain states, including Arizona, already maintain a policy of not changing their clocks for daylight saving time, remaining exempt from the seasonal shifts that the House of Representatives aims to eliminate for the rest of the country.
