What Is the Time Difference Between Houston and Phoenix?

Phoenix remains on Mountain Standard Time (UTC−7) throughout the year. Houston changes between Central Daylight Time (UTC−5) and Central Standard Time (UTC−6).

When Houston is observing daylight saving time, Phoenix is two hours behind Houston. For example, when it is 3:00 PM in Houston, it is 1:00 PM in Phoenix.

When Houston is on standard time, the difference falls to one hour, with Phoenix remaining behind Houston.

Because of this clock difference, the scheduled arrival may appear much earlier than the actual amount of time spent traveling.
