How to calculate
Lists the time zones of Mexico with the local time, abbreviation, UTC offset, and daylight saving in each, for any time and date.
Example with the default inputs (Time 12:00, In Central: Mexico City, Guadalajara, Monterrey, Date September 30, 2026) on the example date Wednesday, September 30, 2026: At 12:00 PM on September 30, 2026 in Central: Mexico City, Guadalajara, Monterrey, Mexico has 4 time zones and 3 UTC offsets in use.
Method: For the typed time in the chosen zone, find the instant (UTC) it names, then show each listed zone’s clock at that instant with its UTC offset, from the browser’s IANA time zone data.
- The zones are IANA tzdata names from zone1970.tab (tzdata 2026a): America/Cancun, America/Mexico_City, America/Matamoros, America/Mazatlan, America/Hermosillo, America/Ciudad_Juarez, America/Tijuana. The browser supplies each zone's offsets and daylight saving rules, so a rule change arrives with a browser update.
- “Time zones” counts the different standard offsets among the listed zones. A zone’s standard offset in a year is the lower of its offsets at 00:00 UTC on January 1 and July 1 of that UTC year.
- “UTC offsets in use” counts the different offsets the listed zones show at that moment.
- Each zone shows its local time, the abbreviation from the browser’s Unicode CLDR English names (left out when CLDR has none), the date as “Tue, Sep 29”, the offset as UTC+hh:mm or UTC−hh:mm, and “daylight saving” when the offset is ahead of the standard offset, “standard time” when the zone’s January 1 and July 1 offsets differ but it is on the standard offset, or “no daylight saving” when they are the same. Because the rule compares January 1 and July 1, a zone that moves its offset for good during a year (Cancún in 2015, Novosibirsk in 2016), or whose January 1 falls in Morocco’s Ramadan change (Casablanca in 2030 to 2033), shows the later offset as “daylight saving” for that year.
- A time that does not exist in the chosen zone (skipped when clocks spring forward) has no answer. A time that occurs twice (when clocks fall back) shows both moments, earlier first, where they differ.

Other questions people ask
How many time zones does Mexico have?
4, under Mexico’s 2022 time zones law: Southeast (Quintana Roo, UTC−05:00), Central (most of the country, UTC−06:00), Pacific (Baja California Sur, Sinaloa, Sonora, and most of Nayarit, UTC−07:00), and Northwest (Baja California, UTC−08:00).
Does Mexico still use daylight saving time?
Most of Mexico does not: it ended on October 30, 2022. Baja California and the municipalities on the US border in Chihuahua, Coahuila, Nuevo León, and Tamaulipas still change their clocks on the US dates, to stay in step with the US side.
Is Cancún on the same time as Mexico City?
No. Quintana Roo keeps UTC−05:00 all year, so Cancún is 1 hour ahead of Mexico City.
