Checking the time now in Dakota isn't as simple as glancing at a single clock. You’ve probably noticed that if you’re looking at a map, there are two Dakotas, and even more confusingly, they both split their loyalty between two different time zones. It's a mess. Honestly, it’s the kind of thing that makes you miss a flight or show up an hour early to a wedding in a small-town church.
Most of North and South Dakota lives in Central Time. But once you cross certain invisible lines—mostly dictated by the winding Missouri River or specific county borders—you’re suddenly in Mountain Time.
Today is Thursday, January 15, 2026. Right now, if you are in Fargo or Sioux Falls, you are likely looking at a clock that is one hour ahead of someone sitting in a coffee shop in Rapid City or Dickinson.
The Great Dakota Divide
The split isn't a straight line. It’s more like a jagged scar. In North Dakota, the majority of the state, including the heavy hitters like Fargo, Grand Forks, Bismarck, and Minot, stays firmly in the Central Time Zone. However, the southwest corner—think Dickinson, Williston, and the stunning landscapes of Medora—operates on Mountain Time.
South Dakota follows a similar, albeit more river-centric, logic. The Missouri River acts as the unofficial boundary.
- East River: Cities like Sioux Falls, Aberdeen, and the capital, Pierre, are in the Central Time Zone.
- West River: Rapid City, Deadwood, and the Black Hills region are all in the Mountain Time Zone.
There is a funny quirk in Pierre, though. While the capital city itself is technically on the eastern bank and observes Central Time, if you drive just a couple of miles across the bridge into Fort Pierre, you're officially in Mountain Time. Locals often joke that you can hit a golf ball into "next week" (or at least the next hour) just by swinging east across the river.
Why does this split even exist?
It's all about commerce and sunlight. Historically, the western parts of these states had closer economic ties to the mining and ranching hubs of the West—places like Billings, Montana, or Denver, Colorado. Meanwhile, the eastern cities were tethered to the railroads and markets of Minneapolis and Chicago.

Daylight Saving in 2026
We are currently in the middle of winter. That means the Dakotas are observing Standard Time.
- Central Standard Time (CST): UTC-6
- Mountain Standard Time (MST): UTC-7
But don't get too comfortable. In 2026, the big switch happens on Sunday, March 8. At 2:00 AM, almost everyone in both states will "spring forward" one hour.
You might wonder if anyone opts out. While some states like Arizona stay the same year-round, both North and South Dakota still play the game. They move to Central Daylight Time (CDT) and Mountain Daylight Time (MDT) like most of the country. This yearly ritual is a headache for farmers whose livestock don't care about what the government says the clock should read.

Dealing with the "Time Warp"
If you're traveling through the region, your phone usually handles the transition for you. Usually.
The problem is the "dead zones" or areas where cell towers from two different zones overlap. I’ve had my phone flip-flop four times in twenty minutes while driving near the border of Sioux County in North Dakota. It's frustrating.
If you are planning a meeting or a dinner reservation in a place like Watford City or Wall, double-check which zone they’re in. It’s common for businesses near the line to specify "Mountain Time" or "Central Time" on their websites because they know how often visitors get it wrong.
A Quick Cheat Sheet for the Major Spots
- Fargo, ND: Central Time (Always 1 hour ahead of Denver)
- Bismarck, ND: Central Time
- Williston, ND: Central Time (Wait, this one is tricky—the city is Central, but the county line is right there!)
- Sioux Falls, SD: Central Time
- Rapid City, SD: Mountain Time (Always the same as Denver)
- Deadwood, SD: Mountain Time
Navigating the Dakotas Effectively
To avoid the "Dakota Time Warp," the best strategy is to set your watch to the destination's time as soon as you start your drive. If you are heading to Mount Rushmore, you are heading into Mountain Time. If you are heading toward the Red River Valley, you are aiming for Central.
For those managing business calls or remote work in 2026, remember that the "time now in Dakota" depends entirely on which side of the Missouri River your contact is standing on.

To stay on track, manually set your phone's clock to the specific city you are visiting rather than relying on "Automatic Time Zone" updates, which can be glitchy near the borders. If you are crossing the state via I-94 or I-90, keep a mental note that the shift typically happens west of Bismarck and west of Pierre.
