What time zone is Mexico City in?

Mexico City uses Central Time. As of 2023, Mexico City (and most of Mexico) no longer observes daylight saving time, so Mexico City is permanently at UTC−6. This is the same as US Central Standard Time (CST) year-round.

Did Mexico City stop observing daylight saving time?

Yes. In 2023, Mexico abolished daylight saving time for most of the country, including Mexico City. The country now stays at UTC−6 year-round. The exception is the northern border region, which continues to observe DST to stay aligned with the US.

How does Mexico City’s permanent UTC−6 affect scheduling with the US?

Since most US cities still observe DST, the offset between Mexico City and US cities changes seasonally. Mexico City aligns with US Central Standard Time in winter (no gap to Chicago/Dallas) but is one hour behind Central Daylight Time in summer.
