New Mexico Time Now
Time Zone
Quick Answer
New Mexico uses Mountain Time — MST (UTC-7) in winter, MDT (UTC-6) in summer.
New Mexico Time Zone
New Mexico is entirely in the Mountain Time Zone. The state uses MST (Mountain Standard Time, UTC-7) from November to March and MDT (Mountain Daylight Time, UTC-6) from March to November. Unlike neighboring Arizona, New Mexico does observe daylight saving time.
New Mexico vs Arizona Time
New Mexico and Arizona are both in the Mountain Time Zone, but they handle DST differently. New Mexico observes daylight saving time, switching to MDT (UTC-6) in summer. Arizona (except the Navajo Nation) stays on MST (UTC-7) year-round. This means during summer, New Mexico is 1 hour ahead of Arizona despite being neighbors. In winter, both states are on MST and share the same time. If you're driving between Albuquerque and Flagstaff during summer, remember to adjust your clock at the state line.
