Most of Texas is Central Time, but El Paso is Mountain Time. The surprising split explained.
Texas is so big it spans TWO time zones. Most people don't know this!
Houston, Dallas, Austin, San Antonio → CST (UTC−6) in winter, CDT (UTC−5) in summer.
El Paso (far west Texas) uses Mountain Time — MST/MDT — same as Denver!
A Dallas–El Paso call at 10 AM Dallas time = 9 AM El Paso time. Always 1 hour apart!
Both zones spring forward Mar 9 and fall back Nov 2 — just at different UTC offsets.
