São Paulo to San Francisco Meeting Time & Timezone Overlap

Working across São Paulo and San Francisco means designing the day around a 5-hour offset — America/Sao_Paulo sits 5 hours from America/Los_Angeles. The two cities share 4 hours of business time, which is enough for one daily check-in but not enough to run two synchronous meetings back-to-back. The page below shows the live hour-by-hour comparison, the cleanest meeting windows, and the DST shifts that change the overlap on specific dates in 2026.

São Paulo–San Francisco working-hour overlap window

The shared working window is 2:00 PM – 6:00 PM in São Paulo (America/Sao_Paulo), which lines up with 9:00 AM – 1:00 PM in San Francisco (America/Los_Angeles).

For recurring meetings the most attendance-friendly start time is 2:00 PM São Paulo time. Booking inside the shared window means neither side has to take the call before breakfast or after dinner.

Daylight saving advisory

San Francisco 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 San Francisco — last Sunday of March (Europe) or second Sunday of March (North America)
  • Autumn shift in San Francisco — 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.

Business-hours context for São Paulo and San Francisco
