Sunday marks the beginning of Daylight Saving Time for 2023. Most of Arizona won’t have to worry about moving their clocks ahead an hour anyway, but if you live on the Navajo Nation, you do. Starting Sunday morning at 2 a.m., people on the reservation will be an hour ahead of the rest of the state. The Navajo Nation goes on Daylight Saving Time to stick with the rest of their territory in other states. For those off the reservation, just go to bed Saturday night and use your clock as you would normally with no changes. A bill remains in Congress that would put an end to clock changing around the country, except for parts of Arizona.
