Current Time in Houston

Time Zone & Business Hours — Houston

Houston runs on Central Time — CST (UTC−6) in winter and CDT (UTC−5) in summer. Known as the energy capital of the world, Houston hosts more Fortune 500 energy companies than any other city and is also home to NASA's Johnson Space Center, making it a dual reference point for global energy markets and space operations.

Houston's oil and gas industry operates around the clock, but the Central Time daylight saving transition still matters: crude futures, refinery shift changes, and cargo vessel schedules all reference CST in winter and CDT in summer across the Gulf Coast.
