Mexico City

Mexico • Central Time (Mexico)

Time Zone

Mexico City uses Central Time (Mexico) (CST / CDT), currently running at UTC−6 (winter) / UTC−5 (summer). Mexico broadly follows U.S. DST rules for most of the country, advancing clocks in spring and falling back in autumn, though exact dates can vary slightly from U.S. transitions.

Business & Commerce

Mexico City, Mexico's capital and one of the largest urban agglomerations in the world, operates on Central Standard Time (CST, UTC−6) in winter and Central Daylight Time (CDT, UTC−5) in summer — the same offset as Chicago and Houston. At CST, Mexico City is one hour behind New York and six hours behind London. The Mexican Stock Exchange (Bolsa Mexicana de Valores, BMV) trades from 8:30 AM to 3:00 PM local time on weekdays. Mexico City's time zone reflects the tight economic integration between Mexico and the United States — Mexico and the U.S. are among each other's largest trading partners, and Mexican manufacturing (especially in the automotive, electronics, and aerospace sectors) is closely coordinated with American production schedules. Just-in-time supply chain timing across the U.S.-Mexico border makes the one-hour difference between Chicago and Mexico City a practical daily matter for cross-border operations.
