Texas is massive. Honestly, you probably already knew that, but the sheer scale of the Lone Star State is the reason why "the timezone of texas" is a trickier topic than most people realize. If you’re planning a road trip from the piney woods of East Texas all the way to the rugged mountains of El Paso, you’re going to lose an hour somewhere along the way. Most of the state sits comfortably in Central Time, but there’s a stubborn little corner out west that plays by its own rules.
It’s about 800 miles across. That’s a lot of ground for one sun to cover.
Most folks assume Texas is a monolith. It isn't. While about 99% of the state’s population lives, works, and eats within the Central Time Zone, two specific counties in the far western tip—El Paso and Hudspeth—are officially part of the Mountain Time Zone. This creates a weird dynamic for travelers and business owners who deal with cross-state logistics. You could be in a Zoom meeting with someone in Dallas while you're looking at a sunset in El Paso that hasn't even started for them yet.
The Great Divide: Central vs. Mountain Time
The majority of Texas observes Central Standard Time (CST) during the winter and Central Daylight Time (CDT) during the summer months. This covers everything from the humid coastal breeze of Galveston to the high plains of Amarillo. When you think of Texas time, you’re thinking of the Central zone. It’s the heartbeat of the state’s economy, aligning Austin, Houston, and San Antonio with the rest of the American Midwest and South.
Then there’s the "Trans-Pecos" region.
If you drive west on I-10, you’ll eventually hit a sign near the Hudspeth County line. That’s where the magic happens—or the confusion, depending on how tight your schedule is. El Paso and Hudspeth counties operate on Mountain Standard Time (MST) and Mountain Daylight Time (MDT). This puts them in sync with neighbors like New Mexico and Arizona rather than their own state capital in Austin. Why? Because geographically and economically, El Paso is much more tied to the mountain region than the Gulf Coast.
Why El Paso Stays Different
It’s basically a matter of longitude. El Paso is actually further west than Denver, Colorado. If the federal government forced El Paso to stay on Central Time, the sun wouldn't rise until nearly 9:00 AM in the winter. That's a miserable way to start a school day or a commute. The U.S. Department of Transportation, which actually oversees time zone boundaries in the United States, recognizes that forcing a single timezone of texas would be a logistical nightmare for the western tip.
Actually, there’s a funny bit of history here. Northwestern Texas, specifically the Panhandle, used to be a bit of a gray area. Back in the early 20th century, as railroads expanded, time was a mess. Every town basically set its own clock based on the "high noon" sun. It wasn't until the Standard Time Act of 1918 that things got formalized. While the Panhandle stayed Central, El Paso eventually lobbied to stay Mountain because their trade was heading west and north, not east.
Daylight Saving Time: The Texas Toss-up
Texas does participate in Daylight Saving Time. This means that for most of the year, we’re all jumping forward or falling back.

- Central Time: UTC -6 (Standard) / UTC -5 (Daylight)
- Mountain Time: UTC -7 (Standard) / UTC -6 (Daylight)
Notice something? During the summer, El Paso (Mountain Daylight) is at the same offset as Dallas is during the winter (Central Standard). It’s enough to make your head spin if you’re trying to coordinate a multi-city wedding or a shipping route.
There has been constant chatter in the Texas Legislature about abolishing Daylight Saving Time altogether. State Representative Will Metcalf and others have frequently introduced bills to keep Texas on a single time year-round. However, even if Texas voted to stay on "Permanent Daylight Time," it would require an act of the U.S. Congress to make it legal under federal law. As of 2026, the biannual clock change remains the law of the land in the Lone Star State.
Surprising Facts About Texas Geography and Time
Did you know that El Paso is closer to the Pacific Ocean than it is to Texarkana? It’s true. When you’re standing on the border in Texarkana, you’re closer to the Atlantic coast than you are to your fellow Texans in the west. This massive distance is why the timezone of texas has to be split.
If you're traveling, keep an eye on your smartphone. Most modern phones use tower triangulation to flip your clock automatically, but if you're driving through the desolate stretches of West Texas where cell service drops out, your phone might get "stuck" on the wrong time. I've seen people show up an hour early to hotel check-ins in Van Horn because their phone didn't realize they'd crossed the invisible line.
- The 90th Meridian: This is the "center" of Central Time. Since Texas stretches so far past it, the western parts of the Central zone experience very late sunsets in the summer.
- The Border Effect: El Paso and Ciudad Juárez, Mexico, usually stay synced. However, Mexico has made its own changes to Daylight Saving laws recently, which sometimes causes a temporary one-hour gap between the two sides of the Rio Grande.
Navigating the Time Change Like a Pro
If you are doing business across the state, always specify the city. Don't just say "10:00 AM Texas time." That doesn't exist. Say "10:00 AM Central" or "9:00 AM El Paso time." It saves everyone a massive headache.
For travelers, the shift usually happens around the town of Van Horn. If you’re heading west, you gain an hour. It feels like a gift. You get an extra hour of vacation. Heading east? You lose it. It's the "Texas Time Tax."
The reality is that Texas is a land of extremes. From the swamps to the deserts, the state is just too big to fit into one neat little box. Understanding the timezone of texas is really about understanding the geography of the American West. It’s a transition zone. It’s where the South ends and the West begins.
Actionable Insights for Dealing with Texas Time:
- Always verify the county: If you are visiting Big Bend National Park or Guadalupe Mountains National Park, double-check your location. Most of Big Bend is Central, but Guadalupe Mountains is Mountain Time.
- Sync your calendars: When scheduling digital invites (Google Calendar, Outlook), use the "Location" feature. The software will automatically adjust the offset for participants in different zones.
- The "Border Buffer": If you’re driving near the Hudspeth/Culberson county line, don't rely on your car's dashboard clock. Those are rarely GPS-linked and won't update.
- Logistics Planning: Truckers and shippers must account for the "lost hour" when moving east from El Paso to San Antonio to ensure they don't miss delivery windows or violate Hours of Service (HOS) regulations.
Texas time is a living thing. It's a reflection of a state that refuses to be categorized easily. Whether you're waking up in the humid sunrise of Beaumont or the high-altitude morning of El Paso, just remember: you're on Texas time, and that's exactly where you want to be.
