Mexico abolished Daylight Saving Time for most of the country in October 2022. As of 2026, only the Baja California border zone continues to observe clock changes, aligned with the US Pacific time schedule. The rest of Mexico stays on a fixed UTC offset year-round.
Mexico's Congress passed a law in October 2022 eliminating DST for most of the country. The last clock change for most Mexican states was on October 30, 2022. Mexico City, Guadalajara, Monterrey, Cancún, and all other major cities now stay on their standard UTC offset year-round.
Only the Baja California "border zone" (Municipio de Mexicali and the Tijuana–Ensenada corridor) continues to observe DST, synchronized with the US Pacific time zone. This exception exists to maintain business continuity with California and other US border states. Baja California springs forward on March 8, 2026 and falls back on November 1, 2026.
Mexico City is on Central Standard Time (CST, UTC-6) year-round since 2022. There are no clock changes. Previously Mexico City was on CDT (UTC-5) during summer — that no longer applies.
Most of Mexico: Central Standard Time (CST, UTC-6) · Sonora: Mountain Standard Time (MST, UTC-7) · Baja California Sur & Sinaloa: Mountain Standard Time (MST, UTC-7) · Baja California border zone: Pacific time, follows US DST (PST/PDT, UTC-8/-7).
