Why don't Arizona and Hawaii participate in Daylight Saving Time?

Answer 1

ArizonaWhen Congress passed the Uniform Time Act in 1966, Arizona tried observing daylight savings for a year and decided to not observe it after much negative reaction. They have never observed daylight savings since.

During daylight saving time (spring through fall), Arizona is on Pacific time. All other months of the year they observe Mountain time. The only exception in Arizona is the Navajo Nation, in northeastern Arizona, which does observe Daylight Saving Time.

HawaiiHawaii is closer to the equator and experiences much less variance in daylight than the rest of the country and therefore opts out of observing Daylight Saving Time.

Answer 2

Arizona and Hawaii do not participate in Daylight Saving Time because they are located closer to the equator, where the daylight hours do not vary as much throughout the year as compared to more northern or southern regions. Additionally, Arizona and Hawaii have decided to opt out of the time change due to various cultural, economic, and historical reasons.
