Does Mexico City observe daylight saving time?

No. Mexico abolished DST for most of the country in 2023. Mexico City (America/Mexico_City) now observes Central Standard Time (CST, UTC−6) year-round.

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 CDT (Central Daylight Time) is UTC−5. Mexico City stays on CST (UTC−6) all year, since Mexico no longer observes daylight saving time.

Summary

This tool shows the real-time local clock for Mexico City, Mexico, using the America/Mexico_City IANA timezone (Central Standard Time, UTC−6). Mexico abolished daylight saving time for most of the country in 2023, so Mexico City now stays on CST year-round. The display updates every second directly in your browser — no server round-trip needed. You also get the full date, day of week, and UTC offset.

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).
