What timezone does Mexico City use?

Mexico City observes Central Standard Time (CST, UTC−6) in winter and Central Daylight Time (CDT, UTC−5) during summer. The IANA timezone identifier is America/Mexico_City.

Does Mexico City observe daylight saving time?

Yes. Mexico still observes DST nationally (clocks spring forward in April and fall back in October), so Mexico City shifts between UTC−6 and UTC−5 throughout the year.

How accurate is this clock?

The accuracy depends on your device system clock, which is typically synchronized via NTP to within a few milliseconds. For most scheduling purposes this is more than sufficient.

Why might this differ from my phone's world clock?

If your device system time is slightly out of sync, or if your OS has a stale timezone database, there may be a small discrepancy. Both tools derive the time from the same source — your local system clock.

Is any data sent to a server?

No. All calculations happen entirely in your browser using the built-in JavaScript Intl API. Nothing is transmitted anywhere.

What is the difference between CST and CDT?

CST (Central Standard Time) is UTC−6 and is used during the winter months. CDT (Central Daylight Time) is UTC−5 and is used during summer when clocks are moved forward one hour.

How it works

Your browser reads its system clock via the JavaScript Date API.
The Intl.DateTimeFormat object converts the UTC timestamp to the America/Mexico_City timezone.
Time, date, and offset values are extracted and formatted for display.
A setInterval loop re-runs this conversion every second so the clock ticks live.
DST status is inferred by comparing the current UTC offset against the standard winter offset (UTC−6).
