Live times in Shanghai and Mexico City
The two cities side by side. The January column uses the winter offsets (Shanghai UTC+08:00, Mexico City UTC−06:00); the July column uses the summer offsets (Shanghai UTC+08:00, Mexico City UTC−06:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Shanghai and time in Mexico City — explain each city's time zone, offsets and daylight saving in full.
The time difference between Shanghai and Mexico City
The difference is constant: Mexico City is 14 hours behind Shanghai on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in Shanghai is always 19:00 in Mexico City. The reason the difference never changes is that neither city observes daylight saving.
To convert a time, add the difference: 09:00 in Shanghai is 19:00 in Mexico City in January and 19:00 in July; 17:00 in Shanghai — the end of the working day — is 03:00 in Mexico City in January and 03:00 in July. To go the other way, subtract it: 09:00 in Mexico City is 23:00 in Shanghai in January. The time difference calculator does the arithmetic for any date, and the UTC to Mexico City page gives the full conversion table for Mexico City.
Meeting overlap between Shanghai and Mexico City
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in Shanghai's working day and shows what time they are in Mexico City.
January
| Shanghai time | Mexico City time | Both working? |
|---|---|---|
| 09:00 | 19:00 | Yes |
| 10:00 | 20:00 | Yes |
| 11:00 | 21:00 | Yes |
| 12:00 | 22:00 | Yes |
| 13:00 | 23:00 | Yes |
| 14:00 | 00:00 | Yes |
| 15:00 | 01:00 | Yes |
| 16:00 | 02:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Shanghai time. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Shanghai time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in Shanghai and Mexico City
Shanghai does not observe daylight saving, so its offset of UTC+08:00 never changes.
Mexico City does not observe daylight saving, so its offset of UTC−06:00 never changes.
The difference never changes, so there is no date on which a standing meeting moves. That does not mean the difference is the same as the difference with a third city — the difference between Shanghai and London, for example, may still move when London changes its clocks. The individual DST pages — Shanghai DST 2026 and Mexico City DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Shanghai (19:00–03:00 in Mexico City). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in Shanghai it is 19:00 in Mexico City in January; when it is 12:00 in Shanghai it is 22:00 in Mexico City; when it is 17:00 in Shanghai it is 03:00 in Mexico City. The difference is 12 hours or more, so the two cities are on different dates for part of the day: when it is Monday morning in Shanghai, it is still Sunday in Mexico City if Mexico City is behind, or already Monday evening if it is ahead. Always state the date as well as the time when you schedule across this pair. Scheduling between the Americas and Asia is the hardest case in time-zone work: the difference is 12 hours or more, so one side's working day is the other's night. The only workable approach is to meet at the edge of the day — early morning in Shanghai and evening in Mexico City, or the reverse — and to keep the meeting short. Rotate the awkward hour week by week, or the same side will always be the one giving up its evening. Record the meeting and share notes, so the side that could not attend can still follow the decision.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in Shanghai and time in Mexico City — explain each city's time zone, and the DST pages — Shanghai DST 2026 and Mexico City DST 2026 — give the exact change dates.
