Daylight saving advisory

Toronto observes daylight saving time; Buenos Aires 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 Toronto — last Sunday of March (Europe) or second Sunday of March (North America)
  • Autumn shift in Toronto — 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.
