Mexico Jet Lag, Time Zone & Day-1 Altitude Planner
Mexico abolished Daylight Saving Time across almost the entire country in 2022: Mexico City, Oaxaca, Puebla, Guadalajara, and Mérida stay on year-round UTC-6 (Central Standard Time), while Cancún & Quintana Roo stay on year-round UTC-5 (EST) and Los Cabos & Puerto Vallarta/Nayarit coast use UTC-7. Even more importantly, Mexico City sits at 2,240 meters (7,350 ft) elevation—use this planner to adjust to both local time and highland altitude on Day 1.
