Taichung is 11 hours ahead of São Paulo on the clock today, but the lived version is that Taichung is wrapping up the working day while São Paulo is still in the morning, and the overlap people actually use is narrow. That gap, more than the raw offset, is what teams have to design around.
In São Paulo, the working day picks up earliest in the financial districts — São Paulo's downtown core wakes early and breaks for lunch at the usual hour. The mood in Taichung is its own story: Taichung settles into the evening at the usual hour, with the local commuter pattern setting the pace. If you are scheduling between the two, the heatmap above marks the rows where both patterns line up.
Daylight saving is the other thing to keep an eye on. Brazil either observes DST or holds a fixed offset year-round; Taiwan either follows its region's DST pattern or stays put all year. When the two changes are weeks apart, the offset between São Paulo and Taichung is one hour off the usual for that stretch — a cliff that catches recurring calendar invites unless your calendar app rebases them automatically. Pin the meeting to a city, not an offset, and the tool handles the rest.
For travellers, the 23h 02m flight is the short version of the story. The longer one is jet lag: roughly one day of adjustment per timezone crossed, which means a trip across the 11-hour gap costs about 11 groggy days on each side. Pilots and cabin crew swear by morning sunlight and an early walk; whatever your routine, the wall-clock numbers above are the source of truth for your first morning in the new city.
