Time in Phoenix, United States
The clock above shows the current local time in Phoenix, United States. It follows the America/Phoenix time zone and adjusts for daylight saving on its own, so it stays right all year.
What are UTC and GMT?
Greenwich Mean Time is the old standard, set at the observatory in Greenwich, London. Coordinated Universal Time replaced it and is what modern time zones are measured against. In everyday use the two are treated as the same.
Why does each country have its own time?
Time zones follow lines of longitude so that noon falls near the middle of the day wherever you are. Countries then round those lines to their borders, which keeps daylight hours lined up with working life.
What do AM and PM mean?
AM covers midnight to noon and PM covers noon to midnight. Midnight is 12:00 AM and noon is 12:00 PM, which is why the 24 hour format is clearer around those two moments.
Does it handle daylight saving?
Yes. Each city is tracked by its time zone, so the clocks shift on the right date for that country without you changing anything.
