Current time in Mexico City

Mexico observed summer time from 1996 until 2022, when Congress passed a new time zone law. Clocks fell back for the last time on October 30, 2022, and the capital has stayed on UTC−6 since. Supporters cited health studies and the small energy savings; polls showed most residents disliked the change.

The law kept exceptions. Municipalities along the US border, such as Tijuana, Ciudad Juárez and Matamoros, still change clocks on the US dates so they stay in step with San Diego, El Paso and Brownsville. Quintana Roo, home to Cancún, has used UTC−5 all year since 2015, one hour ahead of the capital, and Baja California follows Pacific Time.

Because the US still changes clocks, Mexico City's difference with its neighbor changes twice a year. From the first Sunday of November to the second Sunday of March it matches Chicago, Dallas and Houston, is one hour behind New York and two ahead of Los Angeles. During US daylight time it is one hour behind Texas, two behind New York and one ahead of California. London is six hours ahead in the British winter and seven during British Summer Time. For other combinations use the time zone converter, or compare cities on the world clock.

At 19.4° north, Mexico City's day length varies only from about 11 hours in December to about 13 hours 15 minutes in June. Without daylight time, June sunrise comes near 7:00 AM and sunset around 8:16 PM; in December the sun rises about 7:05 AM and sets close to 6:05 PM. January has the latest sunrises, around 7:15 AM.
