How many hours ahead is New York compared to Mexico City?

New York is typically 1 hour ahead of Mexico City. New York observes EST (UTC-5) or EDT (UTC-4) while Mexico City stays on CST (UTC-6) year-round. However, for a brief window in spring and autumn when the two cities switch daylight saving time on different dates, the offset can temporarily be 0 or 2 hours.

Does Mexico City observe daylight saving time?

Mexico City (America/Mexico_City) observes Central Standard Time (CST, UTC-6) and does switch to Central Daylight Time (CDT, UTC-5) during summer months, though the exact transition dates can differ from the US schedule. The live tool always shows the accurate current offset for today.

Does this tool account for daylight saving time?

Yes. The tool uses the browser's built-in Intl.DateTimeFormat API with full IANA timezone identifiers (America/New_York and America/Mexico_City), which automatically applies the correct DST rules for any date throughout the year.

What time zones are New York and Mexico City in?

New York observes Eastern Standard Time (EST, UTC-5) in winter and Eastern Daylight Time (EDT, UTC-4) in summer. Mexico City observes Central Standard Time (CST, UTC-6) and Central Daylight Time (CDT, UTC-5) in summer.

Does the clock use my local computer time?

Yes, it reads your device's system clock and converts it to both timezones. If your device clock is accurate, both displayed times will be accurate.
