Sunday marks the beginning of Daylight Saving Time for 2021. A bipartisan group of U.S. Senators have introduced the “Sunshine Protection Act,” which would make Daylight Saving Time permanent any clock changes would be a thing of the past. Most of Arizona don’t have to worry about moving their clocks ahead an hour anyway, but if you live up on the Navajo Nation, you do. So starting Sunday morning, 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.
