Daylight saving advisory
Mexico City observes daylight saving time; São Paulo does not. The effective time difference between the two cities therefore shifts by one hour twice a year. In 2026, the change dates that matter for this pair are:
- Spring shift in Mexico City — last Sunday of March (Europe) or second Sunday of March (North America)
- Autumn shift in Mexico City — last Sunday of October (Europe) or first Sunday of November (North America)
If you book a recurring meeting that already sits at the edge of the overlap window, expect it to drop out for roughly four weeks each spring and autumn when the windows realign.
