Frequently Asked Questions
Does Phoenix change its clocks in summer?
No — Arizona (except the Navajo Nation) does not observe daylight saving, so Phoenix stays on Mountain Standard Time, UTC−7, all year.
Is Phoenix on Mountain or Pacific time in summer?
By the clock it lines up with Pacific cities like Los Angeles in summer, because they spring forward to UTC−7 while Phoenix simply stays there. In winter it matches Mountain Time cities like Denver.
