The US and Mexico share several time zones, and you must understand the time difference when making international calls. Mexico spans four time zones—Pacific, Mountain, Central, and Eastern—while the US has six primary time zones: Pacific, Mountain, Central, Eastern, Alaska, and Hawaii-Aleutian.

When calling the US from Mexico, consider the following time zone differences:
 

• Pacific Time Zone (PT): Used in western parts of both the US and Mexico, including California and Baja California, where there is little to no time difference.
• Mountain Time Zone (MT): Found in regions like Arizona and parts of Mexico, with a slight difference depending on daylight saving practices.
• Central Time Zone (CT): It covers the majority of Mexico and central US states like Texas. The time difference is usually minimal.
• Eastern Time Zone: Used in states like New York and Florida, this time zone is one hour ahead of Mexico’s Central Time.

Morning or late afternoon are ideal times when the time difference is minimal, particularly between Central and Eastern time zones.

If you’re calling from the Central or Eastern parts of Mexico to the Pacific time zone in the US, late morning or early afternoon works well.
