Central Time (Mexico City)

Central Standard Time in Mexico covers the capital Mexico City and the majority of the country's states. In 2022, Mexico abolished daylight saving time for most of the country through a reform to the Federal Time Zones Law, ending over 26 years of clock-changing. Only municipalities along the US border continue to observe DST to maintain synchronization with their American counterparts. Mexico City, one of the largest metropolitan areas in the world with over 21 million people, is the political, cultural, and economic heart of Mexico. The timezone is crucial for the Mexican Stock Exchange (Bolsa Mexicana de Valores), manufacturing supply chains that serve North American automakers, and the country's booming technology sector. Mexico's Central Time is the same UTC-6 offset as US Central Standard Time, making business coordination straightforward during winter months. The country actually spans four time zones: Central, Mountain, Pacific, and Southeast (Quintana Roo uses Eastern Standard Time). Mexico's decision to end DST was driven by studies showing minimal energy savings and public health concerns about sleep disruption.
