When it is 09:00 in Mexico City it is 02:00 in Sydney in January and 01:00 in July. Sydney is 17 hours ahead Mexico City right now — but it is not constant: the difference is 17 hours ahead in January and 16 hours ahead in July. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in Mexico City and Sydney
The two cities side by side. The January column uses the winter offsets (Mexico City UTC−06:00, Sydney UTC+11:00); the July column uses the summer offsets (Mexico City UTC−06:00, Sydney UTC+10:00).

The time difference between Mexico City and Sydney
The difference is not constant. In January Sydney is 17 hours ahead Mexico City; in July it is 16 hours ahead Mexico City. The difference changes on Sunday, 5 April 2026 (from 17 hours ahead to 16 hours ahead) and Sunday, 4 October 2026 (from 16 hours ahead to 17 hours ahead) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in Mexico City is 02:00 in Sydney in January and 01:00 in July; 17:00 in Mexico City — the end of the working day — is 10:00 in Sydney in January and 09:00 in July. To go the other way, subtract it: 09:00 in Sydney is 16:00 in Mexico City in January. The time difference calculator does the arithmetic for any date, and the UTC to Sydney page gives the full conversion table for Sydney.
Meeting overlap between Mexico City and Sydney
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 Sydney.
January
| Mexico City time | Sydney time | Both working? |
|---|---|---|
| 09:00 | 02:00 | No |
| 10:00 | 03:00 | No |
| 11:00 | 04:00 | No |
| 12:00 | 05:00 | No |
| 13:00 | 06:00 | No |
| 14:00 | 07:00 | No |
| 15:00 | 08:00 | No |
| 16:00 | 09:00 | No |
July
| Mexico City time | Sydney time | Both working? |
|---|---|---|
| 09:00 | 01:00 | Yes |
| 10:00 | 02:00 | Yes |
| 11:00 | 03:00 | Yes |
| 12:00 | 04:00 | Yes |
| 13:00 | 05:00 | Yes |
| 14:00 | 06:00 | Yes |
| 15:00 | 07:00 | Yes |
| 16:00 | 08:00 | Yes |
In January the overlap is 0 hours: there is no hour when both cities are in their working day. 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 Sydney
Mexico City does not observe daylight saving, so its offset of UTC−06:00 never changes.
Sydney observes daylight saving: in 2026 the clocks go forward on 4 October 2026 and back on 5 April 2026, moving the offset from UTC+10:00 to UTC+11:00.
The difference changes on Sunday, 5 April 2026 and Sunday, 4 October 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — Mexico City DST 2026 and Sydney DST 2026 — give the exact dates for each city.
Best meeting windows
In July the best windows are 09:00–17:00 in Mexico City (01:00–09:00 in Sydney) — the same logic, with the July offsets.
Calling and travel notes
When it is 09:00 in Mexico City it is 02:00 in Sydney in January; when it is 12:00 in Mexico City it is 05:00 in Sydney; when it is 17:00 in Mexico City it is 10:00 in Sydney. 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 Sydney if Sydney 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 Oceania is the hardest case after Americas–Asia: the difference is 15 hours or more, and the two cities are on different dates for most of the day. The only workable approach is to meet at the edge of the day and to rotate the awkward hour. A meeting at 09:00 in Mexico City is late evening or night in Sydney — check the tables above before you propose a time, and always state the date as well as the time.

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 Sydney — explain each city's time zone, and the DST pages — Mexico City DST 2026 and Sydney DST 2026 — give the exact change dates.
