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

The world clock shows the current time in both cities live, and the individual city pages — time in Mexico City and time in Hong Kong — explain each city's time zone, offsets and daylight saving in full.
The time difference between Mexico City and Hong Kong
The difference is constant: Hong Kong is 14 hours ahead Mexico City 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 Mexico City is always 23:00 in Hong Kong. The reason the difference never changes is that neither city observes daylight saving.
To convert a time, add the difference: 09:00 in Mexico City is 23:00 in Hong Kong in January and 23:00 in July; 17:00 in Mexico City — the end of the working day — is 07:00 in Hong Kong in January and 07:00 in July. To go the other way, subtract it: 09:00 in Hong Kong is 19:00 in Mexico City in January. The time difference calculator does the arithmetic for any date, and the UTC to Hong Kong page gives the full conversion table for Hong Kong.
Meeting overlap between Mexico City and Hong Kong
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 Mexico City's working day and shows what time they are in Hong Kong.
January
| Mexico City time | Hong Kong time | Both working? |
|---|---|---|
| 09:00 | 23:00 | Yes |
| 10:00 | 00:00 | Yes |
| 11:00 | 01:00 | Yes |
| 12:00 | 02:00 | Yes |
| 13:00 | 03:00 | Yes |
| 14:00 | 04:00 | Yes |
| 15:00 | 05:00 | Yes |
| 16:00 | 06:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Mexico City time. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 Mexico City 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 Mexico City and Hong Kong
Mexico City does not observe daylight saving, so its offset of UTC−06:00 never changes.
Hong Kong does not observe daylight saving, so its offset of UTC+08:00 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 Mexico City and London, for example, may still move when London changes its clocks. The individual DST pages — Mexico City DST 2026 and Hong Kong DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in Mexico City (23:00–07:00 in Hong Kong). 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 Mexico City it is 23:00 in Hong Kong in January; when it is 12:00 in Mexico City it is 02:00 in Hong Kong; when it is 17:00 in Mexico City it is 07:00 in Hong Kong. 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 Mexico City, it is still Sunday in Hong Kong if Hong Kong 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 Mexico City and evening in Hong Kong, 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 Mexico City and time in Hong Kong — explain each city's time zone, and the DST pages — Mexico City DST 2026 and Hong Kong DST 2026 — give the exact change dates.
