The local time at IAH — George Bush Intercontinental Airport is currently 10:22:50 AM on Tuesday, June 16, 2026. IAH sits in Houston, Texas, which uses the Central Daylight Time (CDT), UTC−5:00 from Coordinated Universal Time (UTC).

IAH (ICAO code KIAH) is Houston's largest airport and a major United Airlines hub. Whether you are catching an early departure, tracking an arrival, or coordinating an airport pickup, the live clock above reflects the exact local airport time, updated every second.
What Time Zone Is IAH In?
IAH is in the U.S. Central Time Zone, with the official IANA identifier America/Chicago. It shares the same time as the rest of Houston, plus Dallas, San Antonio, Chicago, and New Orleans. IAH observes daylight saving time: clocks spring forward one hour on the second Sunday of March (CST → CDT) and fall back one hour on the first Sunday of November (CDT → CST). Right now IAH is observing CDT.
Do All Houston Airports Use the Same Time?
Yes. Every airport in the Houston area keeps the same Central Time:
- IAH — George Bush Intercontinental Airport (Central Time, America/Chicago)
- HOU — William P. Hobby Airport (Central Time, America/Chicago)
- EFD — Ellington Airport (Central Time, America/Chicago)
There is no time-zone change when you transfer between Houston airports, so a connection or a switch from IAH to Hobby never shifts the clock.
