Best time to call Chicago from São Paulo
Chicago is 2 hours behind São Paulo. Calling Chicago from São Paulo works best between 11:00–17:00 São Paulo time, which lands at 09:00–15:00 for Chicago. The shared window opens in the São Paulo morning, which is the easier half of the day to protect.
With 6 hours in common there is room for a real conversation rather than a status round-up, and enough slack to move a call by half an hour without losing the window entirely.
Avoid the first and last fifteen minutes of that range. Those edges are where one side is either still settling in or already packing up, and a call that runs five minutes over pushes someone past the end of their day.

Cross-timezone workday overlap and collaboration
6 hours of shared time is enough to run one dependable synchronous block a day. Put anything that needs discussion inside it and let everything else happen in writing.
Treat the gap as a handoff rather than a delay. Whoever finishes first should leave the next step written down and unambiguous; 2 hours later the other side picks it up without needing to ask a question that would cost another full day.
Watch for fatigue on recurring meetings. A weekly call that sits at the very edge of someone's evening is tolerable once and corrosive after a month. If the only workable slot is uncomfortable for one side, rotate it, or accept that the meeting should be a document instead.
Practical rules for this pairing
- Book recurring meetings inside 11:00–17:00 São Paulo time and leave the rest of the day for focused work.
- Keep the first hour after Chicago comes online free of meetings, so anything blocking overnight gets picked up immediately.
- Leave at least thirty minutes of the window unbooked as a buffer for anything urgent.
