What Time Is It in the USA Right Now? A Complete Guide to US Time Zones
The United States spans 6 main time zones, 4 in the continental US alone. Here is what time it is everywhere in the USA right now, plus DST rules, strange exceptions, and how to quickly convert between them.
The Short Answer (and Why It Is Complicated)
If you are trying to find out "what time is it in the USA right now?" — the honest answer is: which part? The United States does not have a single time. It spans six main time zones, from the Atlantic coast all the way to Hawaii, with a gap of six hours between them. When it is 9 AM in New York, it is 6 AM in Los Angeles, 5 AM in Anchorage, and 4 AM in Honolulu. If you need the time right now in a specific US city, you can check it instantly on Clockzilla — every major American city has its own page with the current local time, timezone abbreviation, and DST status. But if you want to understand the big picture of how time works in the USA, this guide will walk you through all six zones, the quirky exceptions, and the DST rules that cause half of America to shift their clocks twice a year.
The Four Continental US Time Zones
The contiguous lower 48 states are divided into four time zones. Eastern Time (ET) covers the east coast from Maine to Florida, plus most of the Midwest — states like New York, Massachusetts, Virginia, Georgia, Ohio, Michigan, and Indiana. In standard time, Eastern Time is UTC−5 (abbreviated EST, Eastern Standard Time). In summer, it shifts to UTC−4 (EDT). Central Time (CT) covers the central states including Texas, Illinois, Tennessee, Minnesota, Louisiana, and Iowa — that is UTC−6 in winter (CST) and UTC−5 in summer (CDT). Mountain Time (MT) covers the Rockies: Colorado, Utah, Wyoming, Montana, New Mexico, and most of Arizona. It is UTC−7 in winter (MST) and UTC−6 in summer (MDT). Pacific Time (PT) covers the west coast: California, Oregon, Washington, and Nevada — UTC−8 in winter (PST) and UTC−7 in summer (PDT). These are the four zones most people mean when they refer to "US time."
Alaska and Hawaii: Two More Zones
Beyond the lower 48, the United States has two more time zones. Alaska Time covers almost all of Alaska and is UTC−9 in standard (AKST) and UTC−8 in daylight (AKDT). The small western Aleutian Islands actually use Hawaii-Aleutian Time (UTC−10 standard, UTC−9 daylight) because they extend west of the main Alaska landmass. Hawaii sits in its own zone at UTC−10 year-round, abbreviated HST (Hawaii Standard Time). Hawaii does not observe daylight saving time, which means the gap between Hawaii and the east coast can range from five hours (during US winter) to six hours (during US summer). If you are ever puzzled why your call with someone in Honolulu feels "one hour farther" in the summer, that is why — Hawaii sits still while the rest of the country springs forward.
US Territories Have Their Own Zones Too
People often forget that the United States includes several overseas territories, each with its own time zone. Puerto Rico, the US Virgin Islands, and the British Virgin Islands all use Atlantic Standard Time (AST, UTC−4) year-round — same as Eastern Daylight Time in summer, but one hour ahead of the east coast in winter. Guam and the Northern Mariana Islands use Chamorro Standard Time (ChST, UTC+10), placing them nearly a full day ahead of the continental US. American Samoa uses Samoa Standard Time (SST, UTC−11), making it one of the latest time zones in the world. Wake Island and a few other tiny Pacific possessions use various Pacific time zones. If you count all of them, the United States actually spans 11 different time zone offsets — more than most people realize.
The Weird Exception: Arizona
Here is where US time zones get confusing. Arizona is in the Mountain Time Zone, but it does not observe daylight saving time. That means Arizona stays on Mountain Standard Time (UTC−7) year-round. In winter, Arizona is on the same clock as Denver and Salt Lake City. But in summer, when those cities spring forward to MDT (UTC−6), Arizona stays put at UTC−7 — which puts it on the same clock as California, not the rest of the Mountain states. Confusingly, the Navajo Nation, which covers a large part of northeastern Arizona, does observe DST (to stay aligned with the parts of the reservation in New Mexico and Utah). So within Arizona, you can literally cross an invisible line and find yourself an hour earlier or later for half the year. If you are driving across Navajo lands in summer, bring a clock.
Indiana and Other Smaller Exceptions
Arizona is the most famous DST exception, but it is not the only strange one. Indiana used to be a patchwork where different counties observed different rules, causing decades of confusion. In 2006, the state mostly unified under Eastern Time with DST, though a small number of counties in the far west and northwest stay on Central Time. Parts of Kentucky, Tennessee, and Oregon are split between time zones along state lines. Nebraska, North Dakota, South Dakota, Kansas, and Texas all have small areas in Mountain Time despite being "Central" states. If you are doing business with anyone in these border regions, do not assume their state’s main time zone applies — check the specific city.
When Does Daylight Saving Time Happen in the USA?
Daylight saving time in the United States begins on the second Sunday in March at 2:00 AM local time — clocks "spring forward" to 3:00 AM. DST ends on the first Sunday in November at 2:00 AM local time — clocks "fall back" to 1:00 AM. For 2026, that means DST begins on March 8 and ends on November 1. During DST, the east coast is on UTC−4 instead of UTC−5, the west coast is on UTC−7 instead of UTC−8, and so on. Hawaii and most of Arizona ignore this entirely. The US and European DST transitions do not happen on the same date: Europe typically shifts one or two weeks later in spring and one week earlier in fall, creating a brief window each year when the transatlantic time difference is temporarily off by an hour from its usual value. This confuses a lot of people scheduling international calls in late March and late October.

Common Scenarios: Quick Conversions
Most people ask "what time is it in the USA" because they need to do one of a few specific conversions. If you are calling East Coast from the West Coast: add 3 hours to your time. 9 AM Pacific is noon Eastern. If you are calling the USA from the UK: London is usually 5 hours ahead of New York and 8 hours ahead of Los Angeles (though this varies by an hour during DST transitions in spring and fall). From India to the US East Coast: subtract 9.5 hours in winter, 10.5 in summer. From Tokyo to LA: subtract 17 hours (or add 7, depending on direction). From Sydney to New York: subtract 14 hours in Australian summer, 16 in winter. Clockzilla’s difference pages — for example, clockzilla.io/difference/london-to-new-york — show these conversions in a full 24-hour table so you can scan for overlapping business hours at a glance.
Why This Matters for Scheduling
The United States is one of the most common destinations for international business communication. Millions of phone calls, video meetings, and scheduled emails cross into US time zones every day. Getting the time wrong by an hour can mean joining a meeting after it has ended, sending an email after business hours, or placing a stock order after the market has closed. And because the US spans three working hours of continental time (plus four more counting Alaska and Hawaii), you cannot just "know" what time it is in America — you have to know which America. A meeting at 4 PM EST is a meeting at 1 PM PST. An 8 AM call from London to New York is a 3 AM call if you accidentally try to reach Los Angeles. The cost of these small mistakes compounds quickly in any global business. Using a trustworthy time reference matters more than most people realize.
The Ongoing Debate About Abolishing DST
If you are annoyed by all these rules, you are not alone. There has been a growing movement in the United States to abolish daylight saving time entirely. In 2022, the US Senate unanimously passed the Sunshine Protection Act, which would have made daylight saving time permanent — meaning no more springing forward or falling back, and the country would stay on DST all year. The bill did not pass the House and has not become law. Several states (Florida, Washington, California, and others) have passed their own laws indicating they want to stop changing clocks, but those laws cannot take effect without federal approval. For the foreseeable future, the US still observes DST. Whether that changes in the next few years is anyone’s guess — but if it does, most of this article will need to be rewritten.
How to Always Get the Right Answer
Given how complicated US time zones are, the safest way to know what time it is somewhere in America is to look it up against a reliable source. Clockzilla covers every major US city with its own page showing the exact current local time, the active timezone name and abbreviation (including whether DST is currently in effect), the current UTC offset, and the date of the next DST transition. For conversions, the difference pages let you see a side-by-side table of any two cities, so you can instantly tell what 2 PM in Chicago looks like to someone in Los Angeles, Honolulu, or New York. No mental math, no wondering whether today is a DST day, and no chance of showing up to a meeting an hour late — which is, in the end, the whole point of knowing what time it is somewhere else.
The Short Version
The United States spans 6 main time zones (Eastern, Central, Mountain, Pacific, Alaska, Hawaii) with 11 distinct offsets when you include its overseas territories. The east and west coasts are 3 hours apart. Most of the country observes daylight saving time from the second Sunday in March to the first Sunday in November. Hawaii and most of Arizona do not. When someone asks you "what time is it in the USA right now?", the correct answer is always "which city?" Check Clockzilla for any US city and get the accurate, current time with timezone and DST status in under a second. No guesswork, no wrong answers.
