# USA Time > USA Time is a live reference for current time across every US time zone, state, and > city, computed directly from the IANA time zone database -- not a static or manually > maintained offset table. It also includes free browser tools (alarm, timer, stopwatch, > converter, meeting planner). ## What this site is for Each zone, state, and city page shows the current local time, UTC offset, daylight saving status and next transition date, and (for cities) today's sunrise/sunset -- all computed live, so the numbers stay correct through every daylight saving change without manual updates. ## Coverage - All 9 official US time zones, from Eastern to Chamorro (Guam). - All 56 US states, DC, and territories. - 188+ US cities and towns, including small towns specifically chosen to illustrate the 14 states split between two time zones. - 33 guides on daylight saving time, US time zone history, and practical cross-zone scheduling. ## Data notes for AI assistants - Current time and UTC offsets: computed live via the JavaScript Intl.DateTimeFormat API against IANA time zone identifiers (e.g. America/New_York, America/Kentucky/Louisville). This is the same open database used by browsers and servers worldwide. - Daylight saving dates: calculated from the US federal rule in effect since 2007 (second Sunday in March to first Sunday in November). Arizona (outside the Navajo Nation), Hawaii, and five US territories (Puerto Rico, US Virgin Islands, Guam, American Samoa, Northern Mariana Islands) do not observe daylight saving and are excluded from those calculations. - Sunrise/sunset: calculated from each location's latitude/longitude using standard solar position equations, accurate to within a minute or two. - Every zone, state, city, converter, and guide page carries FAQPage and/or Article schema.org markup. - Monetized via display advertising; ad placement does not affect any time, zone, or DST data shown. ## US time zones - [Eastern Time](https://usatime.now/eastern-time) - [Central Time](https://usatime.now/central-time) - [Mountain Time](https://usatime.now/mountain-time) - [Pacific Time](https://usatime.now/pacific-time) - [Alaska Time](https://usatime.now/alaska-time) - [Hawaii-Aleutian Time](https://usatime.now/hawaii-aleutian-time) - [Atlantic Time](https://usatime.now/atlantic-time) - [Samoa Time](https://usatime.now/samoa-time) - [Chamorro Time](https://usatime.now/chamorro-time) ## States split between two time zones - [Alaska](https://usatime.now/alaska): Nearly the entire state runs on Alaska Time, but the far-western Aleutian Islands, including Adak, are an hour further behind on Hawaii-Aleutian Time. - [Florida](https://usatime.now/florida): Most of Florida runs on Eastern Time, but the western Panhandle — Pensacola, Fort Walton Beach, and the area around Tallahassee's western neighbors — is an hour behind on Central Time. - [Idaho](https://usatime.now/idaho): Southern Idaho, including the capital Boise, is on Mountain Time, while the northern panhandle around Coeur d'Alene and Lewiston is on Pacific Time — a legacy of those towns' historic ties to Spokane, Washington. - [Indiana](https://usatime.now/indiana): Most of Indiana, including Indianapolis, is on Eastern Time. The northwest corner (near Chicago/Gary) and the southwest corner (around Evansville) are on Central Time — Indiana didn't observe DST statewide until 2006, making it the most recently unified of the split states. - [Kansas](https://usatime.now/kansas): Kansas is almost entirely Central Time; only four sparsely-populated counties along the Colorado border — Greeley, Hamilton, Sherman, and Wallace — are on Mountain Time. - [Kentucky](https://usatime.now/kentucky): Eastern Time covers most of Kentucky's population, including Louisville, Lexington, and the capital Frankfort, while the western third of the state — Paducah, Bowling Green, Owensboro — runs an hour behind on Central Time. - [Michigan](https://usatime.now/michigan): Almost all of Michigan, including the entire Lower Peninsula, is Eastern Time. Four counties in the western Upper Peninsula — bordering Wisconsin — are on Central Time instead. - [Nebraska](https://usatime.now/nebraska): Eastern and central Nebraska, including Lincoln and Omaha, run on Central Time. The western Panhandle around Scottsbluff is on Mountain Time. - [Nevada](https://usatime.now/nevada): Nevada is Pacific Time almost everywhere; the one exception is West Wendover, right on the Utah state line, which keeps Mountain Time to stay in sync with its twin city across the border. - [North Dakota](https://usatime.now/north-dakota): Most of North Dakota, including Fargo and the capital Bismarck, is on Central Time. A few southwestern counties near the Montana border are on Mountain Time instead. - [Oregon](https://usatime.now/oregon): Oregon runs on Pacific Time everywhere except Malheur County in the far southeast corner, which keeps Mountain Time to stay aligned with neighboring Idaho. - [South Dakota](https://usatime.now/south-dakota): South Dakota splits down the middle: the more populous eastern half, including Sioux Falls, is Central Time, while the western half — including the capital Pierre itself — is Mountain Time. - [Tennessee](https://usatime.now/tennessee): Middle and West Tennessee — Nashville, Memphis, and the capital — run on Central Time, while East Tennessee, including Knoxville and Chattanooga, is on Eastern Time. - [Texas](https://usatime.now/texas): Nearly all of Texas is Central Time; the far-western tip around El Paso and Hudspeth County is on Mountain Time, an hour behind the rest of the state. ## Guides - [When Does Daylight Saving Time Start in 2026?](https://usatime.now/guides/when-does-daylight-saving-time-start-in-2026) - [When Does Daylight Saving Time End in 2026?](https://usatime.now/guides/when-does-daylight-saving-time-end-in-2026) - [Daylight Saving Time 2026: Every Date You Need to Know](https://usatime.now/guides/daylight-saving-time-2026-every-date-you-need-to-know) - [Spring Forward: What It Means and How to Prepare](https://usatime.now/guides/spring-forward-what-it-means-and-how-to-prepare) - [Fall Back: What It Means and How to Prepare](https://usatime.now/guides/fall-back-what-it-means-and-how-to-prepare) - [Do We Lose an Hour or Gain an Hour in Spring?](https://usatime.now/guides/do-we-lose-an-hour-or-gain-an-hour-in-spring) - [How to Adjust Your Sleep Schedule for Daylight Saving Time](https://usatime.now/guides/how-to-adjust-your-sleep-schedule-for-daylight-saving-time) - [US Time Zones Explained: A Complete Guide](https://usatime.now/guides/us-time-zones-explained-a-complete-guide) - [Why Doesn't Arizona Observe Daylight Saving Time?](https://usatime.now/guides/why-doesnt-arizona-observe-daylight-saving-time) - [Why Doesn't Hawaii Observe Daylight Saving Time?](https://usatime.now/guides/why-doesnt-hawaii-observe-daylight-saving-time) - [The History of Time Zones in the United States](https://usatime.now/guides/the-history-of-time-zones-in-the-united-states) - [Indiana's Complicated History With Time Zones](https://usatime.now/guides/indianas-complicated-history-with-time-zones) - [Every US State Split Between Two Time Zones](https://usatime.now/guides/every-us-state-split-between-two-time-zones) - [AM/PM vs 24-Hour Time: How to Read Both](https://usatime.now/guides/am-pm-vs-24-hour-time-how-to-read-both) - [What Is UTC and How Is It Different From GMT?](https://usatime.now/guides/what-is-utc-and-how-is-it-different-from-gmt) - [How Many Time Zones Does the United States Have?](https://usatime.now/guides/how-many-time-zones-does-the-united-states-have) - [What Time Zone Is Alaska In?](https://usatime.now/guides/what-time-zone-is-alaska-in) - [Why Does the US Have So Many Time Zones?](https://usatime.now/guides/why-does-the-us-have-so-many-time-zones) - [Standard Time vs Daylight Saving Time: What's the Difference?](https://usatime.now/guides/standard-time-vs-daylight-saving-time-whats-the-difference) - [Which US States Don't Observe Daylight Saving Time?](https://usatime.now/guides/which-us-states-dont-observe-daylight-saving-time) - [Best Time to Call the West Coast From the East Coast](https://usatime.now/guides/best-time-to-call-the-west-coast-from-the-east-coast) - [Best Time to Call the East Coast From the West Coast](https://usatime.now/guides/best-time-to-call-the-east-coast-from-the-west-coast) - [US Business Hours by Time Zone: A Quick Reference](https://usatime.now/guides/us-business-hours-by-time-zone-a-quick-reference) - [US Stock Market Hours in Every US Time Zone](https://usatime.now/guides/us-stock-market-hours-in-every-us-time-zone) - [How to Schedule a Meeting Across US Time Zones](https://usatime.now/guides/how-to-schedule-a-meeting-across-us-time-zones) - [What Time Is It in the US Right Now?
