When Do the Clocks Change in Mexico?
Clocks go back on Sunday, November 1, 2026. At 1:59 AM the clocks jump to 1:00 AM, putting the country on PST.
What Happens, and When
Mexico abolished daylight saving nationwide in 2022. Mexico City stays on UTC-6 year-round, so the gap between Mexico and the United States now changes twice a year purely because the US still switches.
| Zone | Next change | Clocks |
|---|---|---|
| Mexico City | no change | stays on UTC-6:00 all year |
| Tijuana | Nov 1, 2026 | 1:59 AM → 1:00 AM (back) |
| Cancun | no change | stays on UTC-5:00 all year |
Mexico City, Cancun do not change at all, so the gap between there and the rest of Mexico is different in summer and winter.
Which Time Differences Move on Nov 1, 2026
A clock change is only interesting because of what it does to the gap between you and everyone else. These are the differences from Mexico before and after the change — note that a gap only moves if the other side does not change on the same date.
| Difference to | Before | After |
|---|---|---|
| New York | +1:00 | +1:00 — unchanged |
| London | +6:00 | +6:00 — unchanged |
| UTC | +6:00 | +6:00 — unchanged |
| India | +11:30 | +11:30 — unchanged |
| Tokyo | +15:00 | +15:00 — unchanged |
| Sydney | +17:00 | +17:00 — unchanged |
| Dubai | +10:00 | +10:00 — unchanged |
0 of these 7 differences move on the day. The gap to New York, London, UTC, India, Tokyo, Sydney, Dubai stay the same, because those clocks change on the same date — or not at all.
Why Mexico Does Change Its Clocks
The 2022 law ended a practice in place since 1996, on the argument that the energy savings were negligible while the health costs were not. A strip of cities along the US border kept daylight saving to stay aligned with American trading hours.
The practical consequence is that every time difference involving Mexico shifts by an hour on Sunday, November 1, 2026. Anything recurring — a standing call, an automated report, a flight connection — is worth checking across that date, particularly against countries that change on a different day or not at all.
To see the exact gap between any two places on any date, use the time zone converter, or the meeting planner for a whole group at once.

Frequently Asked Questions
Does Mexico observe daylight saving time?
No. Clocks in Mexico do not change, so the local offset from UTC is the same every day of the year.
Why does the time difference to my country still change twice a year, then?
Because the other country moves. If you are scheduling between Mexico and somewhere that observes daylight saving, the gap between you shifts by an hour when their clocks change, not when yours do.
Will my meetings be affected?
Any recurring meeting booked across a clock change needs checking, because the two ends move at different times — or one end does not move at all. The time zone converter shows the exact gap for any pair on any date.
