Mexico uses four time zones:[1][2]
- UTC−05:00: Zona Sureste (Southeast Zone), comprising the state of Quintana Roo;
- UTC−06:00: Zona Centro (Central Zone), comprising all parts of Mexico not included in the other zones, including Mexico City, Guadalajara, and Monterrey;
- UTC−07:00: Zona Pacífico (Pacific Zone), comprising the states of Baja California Sur, Nayarit (except the municipality of Bahía de Banderas), Sinaloa, Sonora, and northwest border municipalities of Chihuahua (Janos, Ascensión, Juárez, Guadalupe, and Práxedis Gilberto Guerrero)
- UTC−08:00: Zona Noroeste (Northwest Zone), comprising the state of Baja California.
Some municipalities near the U.S. border[a][b][c] and the entire state of Baja California observe daylight saving time, setting the time forward one hour on the second Sunday of March at 2:00 and back one hour on the first Sunday of November at 2:00, therefore maintaining the same time as the respective areas across the border in the United States.[1][2]
Mexican law states that remote islands observe the time zone corresponding to their geographic location.[1] According to this rule, in the Revillagigedo Islands, San Benedicto, Socorro and Roca Partida are in UTC−07:00, and Clarion is in UTC−08:00.
