Daylight Saving Time abolished in most of Mexico

The 2022 federal law abolishing Daylight Saving Time across most of Mexico (exceptions: municipalities on the US northern border which retain DST to align with the US) took effect from late 2022 and remains in force through 2024–2026. Time-zone coordination with US partners now varies seasonally — Mexico-City–Eastern US gap becomes 1 hour (summer) or 0 hours (winter) rather than stable 1 hour year-round.
