Until 2022 Mexico City moved its clocks each spring. Since then it has stayed on UTC-6 permanently, so many older calendar entries and printed schedules are now wrong for half the year. Phones update automatically, but manually set devices and old software sometimes still add an hour in April.
The exception is the northern border. Cities such as Tijuana, Ciudad Juarez and Matamoros still follow US clock changes so they stay in step with their US neighbours, which means a trip from the capital to the border can involve a time change that did not exist before.
From November to March, Mexico City matches Chicago and Dallas exactly. From March to November, when the US is on daylight time, Mexico City matches Denver instead and sits two hours behind New York rather than one.
India is 11h30 ahead of Mexico City all year, which keeps scheduling simple: the Mexico City morning at 8:00 is 19:30 in Delhi. Long lunches are normal in Mexico City, so a 15:00 call may run into someone's meal break, and the working day often stretches past 18:00 in return.
No. Mexico City has kept UTC-6 all year since daylight saving was abolished in 2022.
Only in the US winter. When Chicago is on daylight time, from March to November, it is one hour ahead of Mexico City.
No. Mexico has four zones, including Cancun on UTC-5 and Baja California on Pacific Time, and several border cities still observe US-style DST.
