America/Ciudad_Juarez: Time Zone Guide
America/Ciudad_Juarez is the IANA time zone identifier for Ciudad Juarez, a major city in the Mexican state of Chihuahua, located on the border with El Paso, Texas, USA. This zone observes Mountain Standard Time (MST) during standard time and Mountain Daylight Time (MDT) during daylight saving time, aligning its clocks with the U.S. Mountain Time zone. It is one of several Mexican zones that follow the same DST schedule as the United States.
Overview and Usage
America/Ciudad_Juarez applies to the municipality of Ciudad Juarez and its surrounding area in the state of Chihuahua, Mexico. It is the only Mexican zone that uses the identifier Ciudad_Juarez. Other Mexican zones at the same standard offset include America/Hermosillo (Sonora, no DST) and America/Mazatlan (Sinaloa and parts of Nayarit, with DST on a different schedule). The zone is used by the entire population of Ciudad Juarez, estimated at over 1.5 million people, as well as nearby communities that follow the same time.
Offset and Abbreviation
During standard time, the offset is UTC-07:00, commonly referred to as Mountain Standard Time (MST). During daylight saving time, clocks shift forward one hour to UTC-06:00, known as Mountain Daylight Time (MDT). The abbreviations MST and MDT are widely used in business and travel contexts. The offset is the same as that of the U.S. Mountain Time zone, which includes cities like Denver and Salt Lake City, but note that some areas in the U.S. Mountain Time zone (e.g., Arizona) do not observe DST.
Daylight Saving Behavior
America/Ciudad_Juarez observes daylight saving time each year, following the same schedule as the United States. Clocks spring forward on the second Sunday of March at 2:00 AM local time (becoming 3:00 AM MDT) and fall back on the first Sunday of November at 2:00 AM local time (becoming 1:00 AM MST). Recent and upcoming change dates include: 2025-03-09 (MDT), 2025-11-02 (MST), 2026-03-08 (MDT), 2026-11-01 (MST). This DST pattern aligns Ciudad Juarez with its neighboring U.S. city, El Paso, Texas, which also uses the America/Denver zone (MST/MDT). The synchronized DST schedule facilitates cross-border commerce and daily life.
Countries and Cities
The only country using this zone is Mexico. The anchor city is Ciudad Juarez, Chihuahua. Other major cities in the same offset but different zones include Denver, USA (America/Denver), Edmonton, Canada (America/Edmonton), and Hermosillo, Mexico (America/Hermosillo, no DST). Within Mexico, the zones at UTC-07:00 standard time are: America/Ciudad_Juarez (with DST), America/Hermosillo (no DST), and America/Mazatlan (with DST on a different schedule). Travelers should be aware that while Ciudad Juarez and Hermosillo share the same standard offset, Hermosillo does not observe DST, so offsets differ during DST periods.
Practical Guidance for Business and Calls
When scheduling calls or coordinating business hours between Ciudad Juarez and other regions, consider the following: During standard time (November to March), Ciudad Juarez is UTC-07:00. It is 2 hours behind New York (UTC-05:00), 1 hour behind Chicago (UTC-06:00), and 1 hour ahead of Los Angeles (UTC-08:00). During DST (March to November), it shifts to UTC-06:00, aligning with Chicago and becoming 1 hour ahead of Los Angeles. For cross-border coordination with El Paso, Texas, there is no time difference at any time of year, as both use MST/MDT. For calls to Mexico City (UTC-06:00 standard, UTC-05:00 DST), note that during standard time, Mexico City is 1 hour ahead of Ciudad Juarez; during DST, both are at UTC-06:00 (Mexico City uses CDT, Ciudad Juarez uses MDT), so they are the same. For international calls to London (UTC+00:00 standard, UTC+01:00 DST), the difference is 7 hours during standard time (London ahead) and 7 hours during DST (London ahead). Always double-check current DST status, as dates may vary by country.
