What timezone does Phoenix use?

Phoenix uses the America/Phoenix IANA timezone, which is Mountain Standard Time (MST, UTC-7) all year long. Arizona (except the Navajo Nation) does not observe daylight saving time.

Does Phoenix observe daylight saving time?

No. Phoenix and most of Arizona do not change their clocks. The UTC offset remains UTC-7 (MST) every day of the year, making it one of the few major US cities that skips DST.

Is this clock accurate?

The tool uses your device's system clock and the browser's built-in Intl API to convert to America/Phoenix. Accuracy depends on your device clock, which is typically synchronized via NTP and accurate to within a second.

Does this tool call any external server?

No. All computation happens in your browser using the Intl.DateTimeFormat API. No network request is made after the page loads.

Why is Phoenix different from Denver or Salt Lake City?

Both Denver (America/Denver) and Salt Lake City observe US daylight saving time rules, switching between MST (UTC-7) and MDT (UTC-6). Phoenix stays on MST (UTC-7) permanently, so it matches Mountain Daylight Time in summer and Mountain Standard Time in winter.
