How many hours ahead is New York compared to Phoenix?

It depends on the time of year. In winter (when New York is on EST, UTC−5), New York is 2 hours ahead of Phoenix (MST, UTC−7). In summer (when New York switches to EDT, UTC−4), New York is 3 hours ahead. Phoenix never changes its clocks.

Why does Phoenix not observe daylight saving time?

Arizona opted out of the federal Uniform Time Act in 1968. Phoenix and the rest of the state (except the Navajo Nation) stay on Mountain Standard Time (MST, UTC−7) year-round, making it the only major US city that does not shift its clocks in summer.

What time zone is Phoenix in?

Phoenix uses Mountain Standard Time (MST), which is UTC−7. It never changes to Mountain Daylight Time (MDT), so the UTC offset is a constant −7 all year.

What time zone is New York in?

New York uses Eastern Time (ET): Eastern Standard Time (EST, UTC−5) from the first Sunday in November to the second Sunday in March, and Eastern Daylight Time (EDT, UTC−4) the rest of the year.

If it is noon in New York, what time is it in Phoenix?

It depends on the season. In summer (EDT), it is 9 AM in Phoenix (3-hour difference). In winter (EST), it is 10 AM in Phoenix (2-hour difference).

If it is 9 PM in Phoenix, what time is it in New York?

In summer, 12 AM (midnight) the next day in New York. In winter, 11 PM the same day in New York.

How it works

The tool reads your browser clock and displays the current time in both New York (ET) and Phoenix (MST).
Phoenix does not observe daylight saving time, so the offset changes with the season: 2 hours in winter, 3 hours in summer.
Enter any hour and minute in the converter, select your source city, and the equivalent Phoenix or New York time appears immediately.
The converter uses real IANA time-zone rules so the offset is always accurate regardless of the time of year.
Results include a day note when a conversion crosses midnight.

Check whether a live event or webinar works for both cities.
Convert a flight arrival time from ET to Phoenix local time.

Verify meeting invites received in a different time zone.
