Current Time in America/Chihuahua Time Zone

Where America/Chihuahua Applies

America/Chihuahua is used exclusively in Mexico. It covers the entire state of Chihuahua, which borders the U.S. states of Texas and New Mexico. Major cities within this zone include Chihuahua (the state capital), Ciudad Juarez, Delicias, Cuauhtemoc, and Parral. Note that Ciudad Juarez, located directly across the border from El Paso, Texas, uses America/Chihuahua despite El Paso observing Mountain Time with daylight saving. This creates a unique one-hour offset difference between the two sister cities for part of the year.

Standard Offset and Abbreviation

The standard offset is UTC-06:00, meaning when it is noon in Coordinated Universal Time (UTC), it is 6:00 AM in Chihuahua. The time zone abbreviation is CST, which stands for Central Standard Time. This abbreviation is used year-round because the zone does not switch to daylight saving time.

Daylight Saving Time: None

America/Chihuahua does not observe daylight saving time. The offset remains constant at UTC-06:00 throughout the year. This decision was made by the Mexican government, which abolished daylight saving time for most of the country in October 2022. However, some northern border municipalities continue to observe DST to align with the United States. Chihuahua is not among those border exceptions, so it stays on standard time all year.

Comparison with Other Zones at UTC-06:00

Several other IANA zones share the same standard offset of UTC-06:00, but their DST behavior differs. For example, America/Chicago (used in the U.S. Central Time Zone) observes DST, shifting to UTC-05:00 in summer. America/Merida (used in southeastern Mexico) also does not observe DST, similar to Chihuahua. Other zones like America/Matamoros and America/Bahia_Banderas have their own DST rules. This means that during summer, America/Chihuahua aligns with zones that remain on standard time, but is one hour behind zones that switch to daylight time.

Practical Guidance for Scheduling

For business and personal calls involving America/Chihuahua, note the following:

• With U.S. Central Time (e.g., Chicago): During U.S. DST (mid-March to early November), Chihuahua is one hour behind Chicago. For example, 10:00 AM in Chihuahua is 11:00 AM in Chicago. During the rest of the year, both zones share the same time (UTC-06:00).
• With U.S. Mountain Time (e.g., Denver): Denver observes DST, so during summer (MDT, UTC-06:00), Chihuahua and Denver are the same time. In winter (MST, UTC-07:00), Chihuahua is one hour ahead of Denver.
• With Mexico City (America/Mexico_City): Mexico City also does not observe DST, so both zones are always at UTC-06:00. No time difference.
• With Europe (e.g., London, UTC+00:00/UTC+01:00): During European winter, London is 6 hours ahead of Chihuahua. During European summer, London is 7 hours ahead.

Always confirm current DST status for the other party's location, as rules can change.

Historical Note

Before October 2022, Chihuahua observed daylight saving time, shifting to UTC-05:00 in summer. The change to permanent standard time was part of a nationwide reform to reduce energy consumption and health impacts. As a result, America/Chihuahua now has a fixed offset year-round.
