Daylight Saving Time ends on Sunday and most of Arizona won’t have to worry about changing their clocks. However, the Navajo Nation does observe Daylight Saving Time and will have to turn their clocks back. Daylight Saving Time ends at 2 a.m. Sunday morning, which means the Navajo Nation will be back in time with the rest of Arizona. The Navajo Nation is the only place in Arizona that observes Daylight Saving Time, even though there’s a common misconception that all of Arizona doesn’t fall in line with the majority of other states. There was a bill passed in March of 2022 in the U.S. Senate that would do away with the bi-annual tradition, but the House never took it up. Florida Senator Marco Rubio introduced it again in committee, but it has failed to come out. Until Congress takes it up, Daylight Saving Time will run from the second Sunday in March until the first Sunday in November.
