Phoenix

Phoenix operates on Mountain Standard Time (MST), which is UTC−7. Unlike most of the United States, Arizona—and Phoenix—does not observe Daylight Saving Time, so the offset stays at UTC−7 all year round.

The current local time in Phoenix follows UTC−7 throughout the year. Because Arizona skips Daylight Saving Time, Phoenix time never shifts—making it easy to calculate without adjusting for seasonal changes.

Phoenix is 2 hours behind New York during Eastern Standard Time (winter) and 3 hours behind during Eastern Daylight Time (summer). The gap changes because New York shifts its clocks twice a year while Phoenix does not.

Phoenix is typically 7 hours behind London in winter (when the UK is on GMT) and 8 hours behind in summer (when the UK is on BST). Phoenix itself never changes its clocks, so the difference shifts only when London does.

No. Phoenix and most of Arizona remain on UTC−7 (MST) year-round and do not move to Mountain Daylight Time in spring. This makes Phoenix one of the few major US cities with a fixed UTC offset.

Phoenix is 1 hour ahead of Los Angeles for most of the year. During Pacific Daylight Time (spring and summer), Los Angeles moves to UTC−7—the same offset as Phoenix—so the two cities are temporarily on the same time.

Phoenix uses UTC−7 permanently. There is no seasonal adjustment, which means the local time in Phoenix is always 7 hours behind Coordinated Universal Time (UTC).
