Mexico uses 4 time zones: Northwest (UTC−08:00/UTC−07:00 in Baja California), Pacific (UTC−07:00, e.g., Sonora – year round), Central (UTC−06:00 – most of the country, generally year round), and Southeast (UTC−05:00 – Quintana Roo, year round).
Baja California (e.g., Tijuana). Follows the U.S. DST schedule.
Sonora and some Pacific states/areas (e.g., Hermosillo). No DST (year round).
Most of Mexico including Mexico City. Generally no DST since 2022, except certain municipalities along the northern border that align with the U.S. schedule.
Quintana Roo (e.g., Cancún). No DST (year round).
Since 2022 most of Mexico does not observe DST. Exceptions include Baja California and some northern border municipalities which follow the U.S. schedule: begins the second Sunday in March at 2:00 a.m., ends the first Sunday in November at 2:00 a.m. local time.
Mexico historically used DST nationwide, but a federal reform in 2022 eliminated DST for most of the country, retaining it only in Baja California and selected municipalities along the U.S. border to facilitate cross‑border coordination.
