Common questions

How many hours ahead is São Paulo of Sydney?

São Paulo is 13 hours behind Sydney right now. The gap is not fixed: it moves whenever either side changes its clocks.

What is the best time to call between Sydney and São Paulo?

There is no hour inside working hours in both cities. 06:00–07:00 your time (17:00 there) is the cheapest compromise, and one side is taking a shoulder hour.

Do Sydney and São Paulo change clocks on the same date?

Only one of them does, so the gap between them changes twice a year even though neither city moved relative to the sun.
