Mexico spans four time zones. The Zona Sureste (Quintana Roo) uses UTC-5, Zona Centro (including Mexico City and most of the country) uses UTC-6, Zona Pacífico (Chihuahua, Sinaloa, Nayarit) uses UTC-7, and Zona Noroeste (Baja California) uses UTC-8.
In October 2022, Mexico abolished daylight saving time for most of the country. Only municipalities within 20 kilometers of the US border in Baja California continue to observe DST to stay aligned with US Pacific Time. The rest of Mexico now maintains consistent time year-round.
Mexico City is one of the largest cities in the world by population, with over 21 million people in its metropolitan area. Mexico is home to 35 UNESCO World Heritage Sites, more than any other country in the Americas. The country is also the birthplace of chocolate, which the ancient Mayans and Aztecs consumed as a bitter drink.
