Time in Wyoming Right Now

Current Time in Wyoming

In the south-central part of Wyoming, the Continental Divide performs a geographic trick found nowhere else in North America: it splits into two branches and loops entirely around a vast desert basin, leaving the enclosed Red Desert with no drainage path to either coast. Water that falls inside that circle stays there, pooling and evaporating in a closed hydrologic system rather than flowing to any ocean. Wyoming is a state full of anomalies like this — the kind of place where the rules seem to bend slightly. Its time, however, is wholly straightforward: the entire state keeps Mountain Time, ticking along at UTC−7 in winter and UTC−6 during summer DST. The live clock at the top of this page reflects the current Wyoming hour precisely, reading from the America/Denver IANA zone and updating with every passing second.

Wyoming is the least populous state in the United States, with around 587,000 residents spread across nearly 98,000 square miles — a population density lower than any other state. Its capital and largest city, Cheyenne, sits in the far southeastern corner, only about 90 minutes north of Denver. Despite its sparse settlement, Wyoming receives tens of millions of annual visitors: Yellowstone and Grand Teton national parks together drew more than six million visitors in 2022 alone. All of them, from the geysers of the Upper Geyser Basin to the ski slopes above Jackson Hole, keep the same Mountain Time.

What Time Zone Is Wyoming In?

Wyoming occupies the Mountain Time Zone from its northern border with Montana all the way south to Colorado, and from Idaho and Utah in the west to South Dakota and Nebraska in the east. The IANA database entry for this zone is America/Denver, covering Wyoming alongside Colorado, Utah, Montana, and portions of several other states. In winter, Wyoming clocks read UTC−7; when Daylight Saving Time is in effect, they read UTC−6.

The Mountain Time Zone name derives from the Rocky Mountains, which run prominently through Wyoming's western half. The eastern half of the state is a high-elevation prairie — the High Plains — averaging well above 5,000 feet in elevation, making Wyoming the second-highest state by mean elevation after Colorado. Cheyenne itself sits at 6,062 feet, making it one of the highest state capitals in the country. Whatever the terrain, the time zone boundary holds firm: every Wyoming city, national park, and high-altitude ranch reads the same Mountain Time.

Does Wyoming Observe Daylight Saving Time?

Yes, Wyoming participates in Daylight Saving Time on the standard federal U.S. schedule. Each year on the second Sunday of March, clocks jump forward one hour at 2:00 AM, transitioning Wyoming from MST (UTC−7) to MDT (UTC−6). The hour that disappears on that March morning gets returned on the first Sunday of November, when clocks roll back from 2:00 AM to 1:00 AM and MST resumes.

For Wyoming's outdoor economy, the summer MDT hours matter considerably. Yellowstone in June sees sunrise before 5:30 AM local time and sunset approaching 9:00 PM — nearly 15 and a half hours of daylight. The Cheyenne Frontier Days rodeo, held each July and billed as the world's largest outdoor rodeo, draws around 250,000 attendees across ten days of MDT evenings. For fly fishermen on the Snake River and hikers in the Tetons, those extra evening hours under MDT are central to the Wyoming summer experience. Come November, the return of MST marks the transition to a quieter, colder Wyoming — hunting season in the high country, elk migrations through Jackson Hole, and the long, dark stretch leading to a Cowboy State winter.

About Wyoming — Equality State, Cowboy Country, World's First Park

The name Wyoming sounds quintessentially Western, but it originated in Pennsylvania. A congressman from Ohio borrowed it from the Wyoming Valley — a name derived from the Delaware (Munsee) words for "at the big river flat" — and proposed it for the new western territory in 1865. By the time Wyoming Territory was formally organized in 1868, the name had stuck, even though the landscape it described bore no resemblance to the Pennsylvania valley that had given it its sound.

Wyoming Territory earned its other enduring nickname — the Equality State — through an act of government in 1869, when the territorial legislature granted women the right to vote and hold office. It was the first government in the United States to do so. When Congress briefly threatened to deny Wyoming statehood unless it revoked women's suffrage, the territorial legislature reportedly replied: "We will remain out of the Union one hundred years rather than come in without our women." Wyoming entered the Union as the 44th state on July 10, 1890, women's suffrage intact. The following year, Wyoming also became the first state to elect a female governor, Nellie Tayloe Ross, in 1924.

The geological drama on display in Wyoming is difficult to overstate. Yellowstone National Park, established in 1872 as the world's first national park, sits atop one of the largest volcanic hotspots on the planet. Old Faithful erupts roughly every 90 minutes with clockwork consistency. The park's Grand Prismatic Spring is the largest hot spring in the United States and the third largest in the world. Grand Teton National Park, immediately to the south, offers some of the most dramatic mountain scenery in North America — the Teton Range rises almost vertically from the valley floor, with no foothills to soften the transition, creating a skyline that painters and photographers have been chasing since the 1800s.

Wyoming also invented, quietly and unexpectedly, a business entity that would reshape global commerce. In 1977, the Wyoming Legislature created the first Limited Liability Company (LLC) law in the United States — a corporate structure combining the tax treatment of a partnership with the liability protection of a corporation. The LLC form eventually spread to every state and most of the world, and today there are more LLCs registered in the United States than any other business form. It is not the first thing that comes to mind when people think of Wyoming, but it may be the state's most consequential export.
