Dallas uses Central Time (CT) — UTC−6 in winter (CST) and UTC−5 in summer (CDT). Together with Fort Worth it forms the Dallas–Fort Worth Metroplex — the fourth largest metropolitan area in the United States, home to more Fortune 500 company headquarters than any other US metro, and served by one of the world's busiest airports.
Everything you need to know about Dallas's time zone, UTC offset, and Daylight Saving Time schedule.
From the first Sunday of November to the second Sunday of March, Dallas observes CST (UTC−6). In winter Dallas shares this offset with Chicago, Houston, New Orleans and most of Mexico City — a key scheduling advantage for the dozens of Fortune 500 firms in the DFW Metroplex with operations across the Central corridor.
From the second Sunday of March to the first Sunday of November, Dallas advances to CDT (UTC−5). Long, warm CDT evenings fuel the DFW outdoor economy — from Klyde Warren Park and White Rock Lake to the sprawling Southlake Town Square and the entertainment districts in Deep Ellum and Uptown.
The official IANA time zone name for Dallas is America/Chicago. Dallas and Fort Worth share this identifier with all US Central Time cities. It is the zone reference used by AT&T, American Airlines, Southwest Airlines, ExxonMobil and all other DFW-headquartered corporations in their global scheduling systems.

Dallas/Fort Worth International Airport (DFW) is consistently ranked among the top five busiest airports in the world by passenger count. It is American Airlines' largest hub, connecting Dallas on Central Time to all 24 global time zones — London (LHR/LGW), Tokyo (NRT), Frankfurt (FRA), São Paulo (GRU), Seoul (ICN) and dozens more with direct service.
The Dallas–Fort Worth Metroplex is home to more Fortune 500 headquarters than any other US metropolitan area — including AT&T, ExxonMobil (Irving), American Airlines (Fort Worth), Southwest Airlines, Texas Instruments, Kimberly-Clark, and Celanese. Scheduling calls across time zones is a daily reality for tens of thousands of corporate professionals in the DFW business community.
Dallas is the third most populous city in Texas and the ninth most populous in the United States, with approximately 1.3 million residents in the city proper. Together with Fort Worth and its many suburban cities, the Dallas–Fort Worth (DFW) Metroplex forms the fourth largest metropolitan area in the United States, with over 7.8 million people — a figure growing by hundreds of thousands every decade, driven by relentless corporate relocations from higher-cost coastal cities.
No other American metro concentrates as many corporate headquarters. The DFW Metroplex is home to more Fortune 500 companies than New York, Los Angeles, Houston or Chicago. AT&T, the world's largest telecommunications company, anchors its global operations from downtown Dallas. ExxonMobil, one of the largest companies on earth by revenue, manages its worldwide oil and gas empire from Irving. American Airlines and Southwest Airlines — the two largest airlines in the world by passengers carried — both have their global hubs at DFW Airport. Texas Instruments, McKesson, and Celanese round out a corporate ecosystem of extraordinary breadth and depth.
Technology and innovation form an increasingly dominant part of Dallas's economy. The Telecom Corridor in Richardson and Plano — once home to Nortel, Ericsson, Cisco, and Samsung — has evolved into a broader tech and data centre district. Companies including Toyota North America, JPMorgan Chase's Operations Hub, Goldman Sachs, and Charles Schwab have relocated major operations to the DFW area in recent years, drawn by Texas's zero personal income tax, lower real estate costs, and a massive and growing talent pool from universities across the state.
The arts and cultural scene in Dallas is world-class and often underappreciated. The Dallas Arts District is the largest urban arts district in the United States, encompassing the AT&T Performing Arts Center, the Dallas Museum of Art (DMA), the Nasher Sculpture Center, the Crow Collection of Asian Art, and the Winspear Opera House. The city's restaurant scene has exploded in sophistication over the past decade, with Deep Ellum, Uptown, and Bishop Arts District recognised nationally for culinary excellence.

Note on DST transitions: The offsets shown above reflect the current live offset, which changes twice a year due to Daylight Saving Time. The US and Mexico observe DST on different schedules, causing a temporary 1-hour shift between Dallas and cities like Monterrey or Mexico City for a few weeks each spring and autumn. Always verify the exact offset during transition periods for critical cross-border scheduling.
