São Paulo is 5 hours behind Barcelona
Best overlap: 1:00 PM to 6:00 PM in Barcelona is 8:00 AM to 1:00 PM in São Paulo.
Both offices are open during 1:00 PM to 6:00 PM Barcelona time, which is 8:00 AM to 1:00 PM in São Paulo. São Paulo is 5 hours behind Barcelona. That leaves about 5 hours of common time — enough for a meeting or two, so use it deliberately. Watch the DST gap — when Barcelona changes its clocks and São Paulo stays the same, this window slides by an hour.
