Timezone: Mexico City, Mexico

Mexico City follows Central Standard Time (CST), which is UTC-6. One of the largest urban areas in the world, Mexico City’s time is the central reference for the vast majority of Mexican business and government.

The 2022 Reform

For over 25 years, Mexico observed Daylight Saving Time (known as *Horario de Verano*). However, in October 2022, the Mexican government voted to abolish DST for most of the country. Research concluded that the energy savings were less than 1% and that the disruption to the biological clocks of the population was not worthwhile.

The Border Exception

While Mexico City and the interior remain on permanent standard time, many cities along the US border (like Tijuana and Ciudad Juárez) continue to observe DST. This is done to maintain synchronization with the US cities across the border, which are vital for trade and the local economy.

A Cultural Anchor

Mexico is a country with 130 million people spanning multiple timezones, from UTC-5 (Cancun) to UTC-8 (Baja California). Mexico City’s time (UTC-6) remains the official standard for all federal proceedings and the stock exchange (BMV).

Conclusion

Mexico City’s decision to return to "God's Time" (*horario de Dios*), as it is colloquially known, reflects a global trend away from seasonal shifts. On the Epoch Clock, Mexico City is a massive, consistent block of time in the heart of the Americas.
