What are the US time zones?
US law sets each zone’s standard time as Coordinated Universal Time (UTC) minus a whole number of hours, and the Department of Transportation draws the boundaries between them.
| Zone | Standard | Daylight |
|---|---|---|
| Eastern | EST, UTC−5 | EDT, UTC−4 |
| Central | CST, UTC−6 | CDT, UTC−5 |
| Mountain | MST, UTC−7 | MDT, UTC−6 |
| Pacific | PST, UTC−8 | PDT, UTC−7 |
| Alaska | AKST, UTC−9 | AKDT, UTC−8 |
| Hawaii-Aleutian | HST, UTC−10 | Not used in Hawaii |
The law also sets zones for Puerto Rico and the Virgin Islands (UTC−4), American Samoa (UTC−11) and Guam and the Northern Mariana Islands (UTC+10).

How daylight saving time changes the difference
Daylight saving time moves clocks forward an hour at 2 a.m. on the second Sunday of March and back at 2 a.m. on the first Sunday of November. Places that don’t use it keep the same clock all year, so the gap to them changes twice a year: Arizona is 3 hours behind New York in summer but 2 in winter. Hawaii, Puerto Rico, the US territories and most of Arizona don’t use daylight saving time.
On the changeover days two times are odd. When clocks jump forward, times from 2:00 to 2:59 AM don’t happen; this converter reads them as an hour later and says so. When clocks fall back, 1:00 to 1:59 AM happens twice; it uses the first one, while daylight time is still on, and says so. Other countries change on their own dates (Europe in late March and October), and the converter knows those too.

FAQs
When does the time change?
Clocks go forward one hour at 2 a.m. on the second Sunday of March and back one hour at 2 a.m. on the first Sunday of November. Next: forward on March 14, 2027, then back on November 7, 2027.
What time zone is Arizona?
Arizona is on Mountain Standard Time (MST, UTC−7) all year: most of the state doesn’t use daylight saving time. So in summer it has the same time as California, and in winter the same as Denver.
What is PST in time zone?
Pacific Standard Time, UTC−8, the standard time of the Pacific zone (California, Washington, Oregon, Nevada and part of Idaho). In summer the zone uses Pacific Daylight Time (PDT), UTC−7.
What is the MT time zone?
Mountain Time: Mountain Standard Time (MST) is UTC−7, and Mountain Daylight Time (MDT) in summer is UTC−6. Arizona stays on MST all year.
What time zone is EDT?
Eastern Daylight Time, UTC−4: the time in the Eastern zone from the second Sunday of March to the first Sunday of November, one hour ahead of Eastern Standard Time (EST, UTC−5).
What time zone is UTC?
Coordinated Universal Time (UTC) is the time scale every time zone is set from, rather than a US zone. US zones are set by law as UTC minus a number of hours: Eastern standard time is UTC−5, Pacific UTC−8.
