The IANA time zone identifier for Phoenix is America/Phoenix

IANA, or the Internet Assigned Numbers Authority, maintains a public-domain time zone database that contains data and codes representing the history of local time for many locations around the world. Time zones are typically identified by continent or ocean and then by the name of the largest city within the region containing the clocks. For example, America/New_York represents most of the US Eastern Time Zone, and America/Los_Angeles represents the Pacific Time Zone.

The IANA time zone identifier for Phoenix, Arizona is America/Phoenix. This identifier represents most of Arizona, which uses Mountain Standard Time (MST) without observing daylight saving time (DST). Phoenix does not change between summer and winter time.

The IANA time zone database is used by several implementations, including the GNU C Library, Android, FreeBSD, NetBSD, OpenBSD, ChromiumOS, Cygwin, MariaDB, MINIX, musl libc, MySQL, webOS, AIX, iOS, macOS, Microsoft Windows, OpenVMS, Oracle Database, and Oracle Solaris.

The database contains a history of offsets from Universal Time (UT), which is Greenwich Mean Time (GMT) with days beginning at midnight. For timestamps after 1960, UT is more precisely Coordinated Universal Time (UTC). The database also records when DST was in use, along with some time zone abbreviations such as EST for Eastern Standard Time in the US.

The IANA time zone database is updated periodically to reflect changes made by political bodies to time zone boundaries and DST rules.

Phoenix is 2 hours behind Washington DC

It is important to be aware of time differences, especially when coordinating events or travel between different parts of the country. Phoenix, Arizona, is currently two hours behind Washington, D.C., presenting a notable time disparity between these two major US hubs. This time difference remains consistent throughout the year, unaffected by daylight saving time adjustments.

When it is 9 a.m. in Washington, D.C., it is only 7 a.m. in Phoenix. This two-hour gap can significantly impact the coordination of meetings, events, and travel plans. For example, a business meeting scheduled for 10 a.m. in Washington, D.C., would require participants in Phoenix to join at 8 a.m. local time, potentially affecting their morning routines and commute.

The time difference also influences travel plans, especially for those traveling between Phoenix and the East Coast. A flight departing Washington, D.C., at noon local time would arrive in Phoenix roughly two hours later, adjusting for the time change. This time difference can be advantageous for travelers, offering either a productive morning or a relaxed start, depending on their direction of travel.

Understanding and accounting for this two-hour time disparity are crucial for effective planning and coordination. Whether organizing meetings, scheduling events, or arranging travel, ensuring that all participants are clear about the time zone difference prevents confusion and misalignment. This awareness is particularly relevant for those coordinating activities involving multiple US regions, underscoring the need to adapt and align schedules accordingly.

There is no daylight saving time in Phoenix in 2025

Phoenix, Arizona, is in the Mountain Standard Time (MST) zone, which is UTC/GMT -7 hours. Unlike most other states in the US, Arizona does not observe Daylight Saving Time (DST). This means that in Phoenix, the clocks do not 'spring forward' or 'fall back' at any point in the year.

In 2025, there will be no DST in Phoenix. The sun will rise at around 7:30 am and set at around 5:30 pm, with minor variations in exact times throughout the year. Throughout 2025, Phoenix will be two hours behind Washington, DC, and three hours behind New York when New York is observing DST.

The history of DST in the US is tied to energy conservation. During DST, there is more sunlight during the evening, meaning that homes do not need to turn on lights as early. This leads to energy and fuel savings. However, Arizona's exemption from DST is also related to energy conservation. A 2008 report from the US Department of Energy found that not changing clocks could save around 0.5% of electricity per day for the country, which is enough to power 100,000 homes over a year.

Arizona's exemption from DST is also due to the state's hot climate. If Arizona observed DST, the sun would stay out until 9 pm in the summer. An Arizona Republic editorial from 1969 stated that it is "still hot as blazes" at that time of night and that it is difficult to convince young children that it is bedtime.
